32
Engineering, manufacturing,
and assembly
Our main solutions are oriented towards High Voltage (HV) substation telecontrol, Medium Voltage (MV)
primary and secondary distribution telecontrol (or
transformer stations), as well as towards hydroelectric
power stations telecontrol.
In hardware, these solutions are based on our Remote Terminal Units (RTU), Setis and Idacs, and on
several communications equipment which allow the
implementation of multi-medium distributed architecture networks (RTC, Ethernet, analog radio, digital radio TETRA, ADSL, PLC, GSM/GPRS, etc.), and
multi-protocol (IEC 60870-5-101, IEC 60870-104,
IEC 60870-5-103, DNP3.0, IEC 61850, MODBUS,
PROCOME, m-Link, SPABUS, etc.).
In software, SEMI completes its offer with its tools
Control Suite (stand-alone or multi-site SCADA work-
• Hamlet, a configuration and maintenance tool.
• Dr. Sam, a web server-based remote consulting
tool.
This type of architecture allows adaptation to the
available communication media (RTC; GSM/GPRS;
Ethernet or PPP for tetra radio, ADSL modem or PLC
connections) and the communication with different
IED (Intelligent Electronic Devices), through different
field protocols (IEC 60870-5-103, Procome, Modbus,
etc.)
ing either as local or remote terminal in a control
center); Dr. SAM, a web-server-based supervision and
monitoring tool; and several setup and simulation telecontrol system tools.
Over the years, we have put together the efforts of
our R&D, Engineering, After-Sales and Maintenance
departments to offer an all-in-one solution to the market: design, installation and commissioning of turnkey
telecontrol solutions.
Distributed Architecture RTU
Our goal is to automate, monitor and control electrical installations, both local and remote, effectively and
efficiently. This is why through the distributed architecture RTU we are able to offer a comprehensive, scalable, open and secure solution that minimizes costs.
The distributed architecture network is based on the
following components:
• RTU (Telecontrol Remote Units) of the Idacs family, conceived for the control and supervision of
large-scaled industrial facilities.
Medium-Voltage Secondary
Distribution
With its RTU (Remote Telecontrol Unit), SEMI offers a
flexible and low-cost solution for monitoring and controlling medium-voltage grids.
This solution allows distributing companies to improve
service quality. This is a significant challenge, given
the large volume of points to be controlled and the
typical varied communication media in medium-voltage grids.
This solution allows to establish real-time telecontrol
networks, with proprietary infrastructure (analog radio, Tetra, etc.), or third-party infrastructure (GPRS,
RTC), adaptable to the needs of each utility.
The proposed architecture is based on the Setis family RTU, and especially designed for MV grid, IdacsGW101104 and Idacs-PRX104 concentrators, and
SCADA Control Suite.
Mimetizations and
Designer Structures
Mimetizations
With the aim of reducing the visual impact of the radiating systems of mobile telephone base stations, SEMI
currently designs, manufactures and installs masts that
can be camouflaged with non-metallic structures, permeable to the radiofrequency of these services (GSM/
DCS/UMTS). So far we’ve imitated chimneys with the
same color and shape as the ones in their surroundings, but others similar to any type of structure could
also be built. All the accessories, cables, antennas,
stairs, platforms, fall arrest systems, etc. are contained
within such structures.
Billboards
• Setis telecontrol devices that act within an installation as RTU capture/action modules.
• Control Suite, a SCADA especially designed for
the telecontrol of electrical networks, with communication over the IEC 61850, IEC 60870-5101/104 or DNP3 protocols.
A particular case of synergies with advertising is the
shared use of towers supporting billboards. In such
cases, the inside is used to place hidden antennas behind panels with material transparent to radio waves.
Designer Structures
Occasionally and mainly in urban areas, the solution
adopted has been to build exclusive designer struc-
33
Reinforcement of existing
structures
The shared use of telecommunications structures, the
increase in the number of radio systems and opera-
tures. This option is based in proposals from architecture firms, but adapted and scaled up by SEMI to be
used as antenna support towers.
Special Solutions
Base Stations on HV Power
Lines
The large and necessary proliferation of power lines
for energy transport requires metallic towers for their
installation. Some, especially those used in high-voltage power lines, have significant bracket supports.
Under certain restrictive conditions, they can also be
shared for use as mobile telephone base stations.
34
tors, etc., after a study or a recalculation of the load
supported by the structure, all require a higher tower
load-bearing capacity.
Instead of being replaced by other new structures,
with the subsequent cost increase and inconveniences
from total service interruption during installation, it
frequently requires a more efficient solution such as
the reinforcement of the already-existing structure.
Therefore, inconveniences derived from complete restoration would be greatly reduced.
Such reinforcements can also be applied to structures
with corrosion deterioration installed in untreated
steel with poor paint preservation, which have gradually lost section and stability. In some of these cases,
the solution has been to completely replace the structure with a new one: a parallel structure is installed
on the inside or outside, and then the deteriorated
one is disassembled with minimum or even no service
interruption.
Autonomous Mobile Stations
These stations are equivalent to a mobile rural location and adaptable to different terrains without the
need for civil works. Also, they offer the advantages
and characteristics of fixed conventional stations.
This proposal offers quick-to-implement temporary
solutions for coverage of events, new clients and/or
services, replacement of conventional stations, etc.
This type of stations entails a tower supporting structure, a standard control house and a generating set
with its storage tank. To be highlighted is its temporary
nature, allowing the obtaining of permits from correspondent authorities to be easier.
Lightning Arresting System
For lightning arresting, we have innovative solutions
through inhibiting devices that avoid direct lightning
strike on station elements (towers, buildings, etc.). This
system reduces damages on telecommunications facilities and equipment.
SEMI conducts the design and study of lightning arresting, measuring the number of inhibitors necessary,
and terrain resistivity through geoelectrical methods.
The company also carries out the design of ground
networks.

Our technical resources are among the most innovative and advanced in the market, such as the fivephase decontamination, state-of-the-art depressors
or laser particle counter.
Energy Efficiency
Our company’s multidisciplinary team can carry out
activities and projects with the highest energy efficiency. This is how it assesses the adoption of several responsible habits, measures and investments at
a technological and management level (both in R&D
projects and in sustainable building), which contribute
to reduce energy consumption without affecting our
comfort and life quality.
Environmental
Measurements
SEMI also installs facilities and infrastructures for earth
environmental data control and collecting networks.
The information collected by the sensors is sent via
satellite to a database for its subsequent analysis and
for preparation of studies on ecological footprint and
climate change.
Energy efficiency should not only be applied to our
homes. This is why SEMI has a standardized and approved energy saving system —by several operating
companies— through hot air extraction in BTS cabins, allowing the reduction of electricity consumption
as the number of times HVAC systems are ignited is
lower.

Remote Telecontrol Units
Manufacturing
The products developed by SEMI are integrated by
remote terminal units (RTU), small-sized supervisory
control and data acquisition centers (SCADA), and telecontrol and teleconfiguration applications.
The collection formed by our remote telecontrol units
and their associated tools are an independent system
oriented towards local process control and automation, both for electrical applications (demands in this
sector have justified their development), and for general-purpose industrial control applications.
Remote Telecontrol Units
The family of the so-called Remote Telecontrol Units
(RTU) Idacs/Setis was first designed for the telecontrol of medium and large-scale electrical facilities, although they can be used for more general purposes.
This range consists of a collection of devices installed
within the facilities to be controlled. They are designed
to carry out specific functions.
An Idacs is a Remote Telecontrol Unit with an input capacity of up to 10,000 control points which allows for
the telecontrol, in real time, of all kinds of industrial installations, even if they are located in particularly hostile environments. It has a large information storage
capacity and allows the installation to be controlled
either locally or remotely, managing communications
with several control centers.
Setis (Intelligent Scalable Telecontrol System)
The Setis RTU (Remote Telecontrol Unit) is a modular device endowed with a certain degree of intelli-
52
gence that captures and processes information about
an installation and manages communications with
a control centre, transmitting this information over a
communications network. In this way, it is possible to
remotely control the installation.
ModGP
Communications Equipment
ModCOM
Our equipments have been designed to allow communication between remote devices, adapting the data
transmission to the already-existing different media.
Communications can basically be established as follows:
Device for use with GPS (Global Positioning System)
antenna which acts as a transmitter of configuration
data and a receiver of antenna data and PPS (Pulse
Per Second) signals.

HISTORIC MILESTONES
1919
SEMI is created
The company is created with the aim of designing and
building industrial facilities. During its first years, it
shapes its innovative and pioneer vocation, specializing in the development and commissioning of the
national energy transmission network, including highvoltage electric power lines and substations.
construction of communications infrastructures: TV,
radio, mobile telephone, and GSM-R repeaters; radar
and maritime rescue stations; optical fiber networks,
real-time data weather stations, etc.
1969
Impulse to the National Radio Shortwave
Broadcasting Station
Project for the construction of a National
Power Grid
SEMI builds the antenna field for the Noblejas Shortwave Broadcasting Station, from where the emissions
for Radio Nacional de España (RNE) are transmitted
to Eastern Europe, the Middle East, Australia, northern
Africa, Equatorial Africa and America.
SEMI presents the “Project for a National Power Grid
in Spain”, which implies the creation of a Body, the
precursor of the current Red Eléctrica de España (REE).
1970-1979
1928
1935
Precursors of the change of energy transmission network to 400 Kv.
Railway Electrification Madrid-Ávila-Segovia
In the 70s, SEMI designs and builds the first transformation carried out in Spain for a duplex 220 Kv to a
triplex 400 Kv line, Madrid-La Mudarra.
SEMI has been present in the railway field since 1929.
The company started its activities with the electrification of the Madrid-Ávila-Segovia line, the first one to
be carried out by a Spanish company in Spain.
1982
This project was started for the Compañía de los
Caminos de Hierro del Norte de España, after integrated in RENFE.
Works were interrupted by the Spanish Civil War.
Therefore, electrification could not be concluded until
1946. It was then concluded for RENFE (created in
1941).
1940
SEMI: Pioneer in Spain for very high-voltage power lines
SEMI designs and builds for Endesa the PonferradaValladolid line, the first one in Spain for 220 Kv voltage.
1950
Pioneers in the emergent telecommunications infrastructure
The will of advancing and settling in new scenarios
helped the company to establish itself in the telecommunications field. Since then, SEMI has maintained
great activity in all operations linked to the design and
Infrastructure deployment for the 1982
FIFA World Cup TV rebroadcasting network
Held in Spain with “Naranjito” as mascot, the “82 FIFA
World Cup” implied the previous necessity of upgrading the infrastructures for the Spanish television (TVE),
and Spanish National Radio (RNE) stations covering
the information. A very relevant project awarded to
SEMI, who was responsible for the building, reinforcement and enlargement of many broadcasting stations.
Among them were the ones at Pozo de las Nieves (Las
Palmas), Arguís (Huesca), El Viso (Zamora), Torrente
(Valencia), Jaizquíbel (Guipúzcoa), as well as the 46m
metallic Tower installed on the Pirulí de Torrespaña
(Madrid).
1990-1999
Participation in the new network infrastructures for mobile and fixed communications operators
In the 90s many telephony licenses were awarded
in Spain to different telecommunications operators.
These dealerships allowed SEMI to actively participate
in the deployment of new mobile or fixed networks, at
national and international level.
55
On the one hand, the company was the favored bidder of the construction of Base Stations by the four
mobile telephone operators in Spain, as well as in
Portugal, Morocco, Mexico, Central America, and
Venezuela. At the same time, optical fiber networks
were deployed both for cable operators and for electric companies using energy transmission networks.
Another milestone for the company occurred at the
EXPO’92 and the Olympic Games, which represented
a significant improvement of Spain’s image at an international scale. They showed the rest of the world
the technical capacity of the companies participating
in the large transport and communications infrastructures built for the two events.
On the same year, design and construction of the rail
catenary for 350 km/h are performed.
2000
Storm and Solidarity with France
The company starts in France building and rebuilding
works for EDF, after the storms occurred in the neighboring country in December 1999.
For such occasion, SEMI built the Tower for the Telephone Station in the Cartuja island. It also carried
out many works for communications stations at the
Olympic Villa that would guarantee the coverage of
both events.
Upon request for international collaboration launched
by EDF, SEMI cooperated by sending specialized personnel in high and very high voltage works for the
quick reestablishing of service and reconstruction of
the French electric power grid.
In addition, SEMI participated in the electric infrastructure of the NAFA Project (New Railway Access to
Andalusia), and in the mobile telephone coverage of
the new rail layout, on which the Madrid-Sevilla AVE
runs. In collaboration with the Japanese company
NEC Corporation, SEMI installed the antennae for
the Telefónica Satellite Communications Stations in
Armuña de Tajuña (Guadalajara) and Agüimes (Canarias).
Over the years, SEMI was certified by SDF and was
permanently established in France through the creation of our subsidiary SEMI France.
1997
Beginning of building activities and turnkey projects for renewable energy generation
Being anticipated to the present challenge of renewable energies, SEMI has been executing “turnkey
projects” regarding wind power, PV and solar thermal
power for many years. The company’s commitment to
renewable sources and the environment.
1998
Design and construction of 350km/h railway catenary
The company gives a step forward with the design of
the EAC-350 catenary. Such project was funded by
the MINER and the CDTI. It was performed with the
collaboration of the Pontificia de Comillas University,
and the Mining Engineering Superior School of the
UPM.
The result of this research was fulfilled with the catenary prototype for alternating current and 350 km/h
speed, named C-350, accepted and installed in three
kilometers of the Madrid-Sevilla AVE line to undergo
real tests.
56
On December 15th 1998, tests were carried out with
AVE trains which successfully reached and surpassed
the speed for which the new catenary had been designed.
2002
SEMI, a company with international dedication
In 2002, the company starts implementing its international expansion plan. After executing several projects
in different countries, SEMI decides to definitely establish itself in Morocco, Mexico and Costa Rica.
2003
Development of new railway electrification systems
In 2003, the Railway Infrastructure Manager (GIF)
awards SEMI the “Project, installation and maintenance of the LAC (GIF Polyvalent Catenary, called
Dual Current CPG) on the test stretch of the three-rail
track between Olmedo and Medina del Campo”.
This was the first project in which hybrid technologies
are applied to satisfy the necessity of mixed passenger
and freight corridors; they are also susceptible to being operated in 3 KV DC and 25 KV AC. The goal
is for all the corridors to be certified for any type of
European operator.
SEMI’s engineering development to solve this problem
will be the design chosen for the implementation of
mixed-traffic lines in the Spanish network.
2004
SEMI France
In 2004, SEMI France becomes a reality. It is formed
as an independent company with great potential, and
as the support for expansion throughout Europe.
2009
SEDMIVE is created
Usually known as “SEMI Venezuela”, in 2009 SEMI’s
activities are expanded through SEDMIVE.
2010
Exporting technology for rail transport
The high-speed system developed by SEMI, with European interoperability certificate since 2008, becomes
state-of-the-art technology and engineering, suitable
for its international implementation and export in any
similar project.
2010
Italy and Panama
Following the international strategic plan, SEMI establishes itself in Italy and Panama through two new
companies: SEMI Italia and SEMI Panama.
