AIRCRAFT WARNING SPHERES
STANDARD MODEL (WARNING SPHERES)
FOR TRANSMISSION LINES
AERIAL DAYLIGHT WARNING SPHERES for electrical networks are recommended for
visual signaling for helicopters, airplanes, balloons and others, preventing the collision of
these flying objects with the electrical transmission and distribution lines.
Due to the specific installation conditions, different models have been designed, aiming at
minimizing the inconveniences caused by hard-to-reach locations, uneven relief, road
crossing, etc.
Ref.: ESR-500 and ESR-600
Specific for transmission lines, the AERIAL DAYLIGHT
WARNING SPHERES - Standard Model are recommeded
for use on steel lightning conductors. They are provided
with a conductor fitting system, composed of aluminum
alloy brackets and hexagonal head screws, hot dip
galvanized steel washers and nuts and rubber supports
which are previously adjusted for fixation on conductors of
diameters from 6,35mm to 22,22mm (1/4” to 7/8”).

the installation
mechanism
Due to screws with different lengths, such system
permits to open and assemble the sphere on the
conductor, without removing it completely.

TECHNICAL DETAILS
- Manufactured with poliester resin
- Fiberglass reinforced
-Iso-Aliphatic GEL-COAT Surface
Finishing
- Aliphatic polyurethane painting
-Meets all Brazilian Electrical Utilities
requirements and ABNT-03:011.11-008
standard requirements.

The WARNING SPHERES for installation from
helicopter have a special counter-weight fixation
system, developed by RITZ DO BRASIL S.A. (Patent
Pending), with an opening and coupling mechanism
operated by a single eye-screw, using a specific
RITZGLAS® grip-all clamp stick. This allows for a quick
and safe installation of the sphere on the transmission
line, directly from the helicopter.

FOR OPGW CONDUCTORS
Ref.: ESRR-600
Ref.: ESRO-600
Revolutionary conception that permits the remote installation of the WARNING SPHERE using remote
control, shielded against electromagnetic field interference of transmission lines.
Note: Upon request, the installation robot can also be supplied.

The WARNING SPHERES for OPGW conductors have been
developed to prevent possible damages to the conductor,
either for OPGW conductors or guard-conductors.
FITTING SYSTEM
Holes for
water drainage
Fitting System with
wire formed shield
and grip
The ESRO-600 WARNING SPHERES are provided with a
fitting system, using special aluminum alloy brackets, rubber
conductors support and hot dip galvanized screws, nuts and
washers.
Aluminum alloy wire formed shield and grip are part of the
fitting system as well, to prevent the OPGW conductors from
being damaged.
Installation Robot developed in cooperation with Furnas.
