CORPORATE PROFILE
Workers put the finishing
touches on insulators in the
early days.
The first tunnel kiln to be
installed at our factory at
company headquarters. (1920s)
One of the first “special high-voltage insulators”
to be produced in Japan
The electrification gradually began to gain traction at the end of
the 19th century. At the time, Japan relied on imports for
high-voltage insulators. Japanese high-voltage insulator R&D
and production began only with a desire to make a contribution
to the country by producing insulators locally and a piece of an
American insulator to study. Despite such humble beginnings,
NGK Insulators has consistently succeeded in developing
ultra-high-voltage, ultra-high-strength insulators to meet the
massive demand for electricity of rapidly evolving lifestyles and
developing industries. As a result, we have grown into the
world’s foremost manufacturer of insulators underpinning
power supply the world over.
Here at NGK Insulators, our formidable technological
strengths, honed by long years of experience in the production
of ceramic insulators, have enabled us to further develop a
range of new technologies which are now contributing to the
development of the energy, ecology and electronics sectors.
These include the world’s first large-capacity storage batteries,
which are paving the way for next-generation infrastructures;
vehicle exhaust cleaning components that provide a major
leap forward in the fight to overcome environmental issues;
industrial machinery that provide momentum for chemical
industries; and the precision machinery that underpins the
evolution of electronics.
All of us at NGK Insulators are committed to leveraging our
original ceramic technologies to advance the creation of
things that meet the needs of all society and promote the
betterment of the whole world.

The world’s first large-capacity electric energy storage system
and a major leap forward in the ability
to provide a stable supply of renewable energy.
Using original and highly advanced ceramic technologies, we at NGK were the first
in the world to commercialize a NAS battery system that had the capacity to handle
“megawatts” of electricity.
The NAS battery system boasts an array of superior features, including large
capacity, high energy density and long life. It is capable of maintaining a high output
of electric power for long periods of time despite being only one-third the size of
conventional lead batteries. NAS batteries are the ideal system for reducing peak
electricity use, charging at night when demand is low and providing power during
peak times in the day. Moreover, the NAS battery system can be used as an
emergency power supply during power outages and momentary drops in voltage.
NAS batteries can temporarily store and release energy from weather-sensitive
power sources such as wind and solar power generators, helping to stabilize the
supply. As such, they are attracting interest around the world as useful storage
components for the further spread of renewable energy and the establishment of
next-generation “smart-grid” transmission networks.
NAS battery systems already have a record of
operation in more than 190 locations worldwide.
NAS batteries have sodium (Na) negative electrodes
and sulfur (S) positive electrodes separated by a

Insulators
Uncompromising quality and advanced technology are why our
insulators are chosen to sustain power supply the world over.
Insulators play an important part in maintaining the safety and stability of our energy
lifeline by ensuring that transmission lines and steel towers and equipment are
completely isolated. Given the magnitude of their task— even the slightest defect could
have massive consequences—insulators are required to be impeccably reliable. We at
NGK Insulators are the insulator specialists; since the company’s inception in 1919, we
have consistently developed our own unique technologies and created products with the
durability and quality to perform without fail even in harsh environments that suffer from
earthquakes, typhoons and heavy snowfall. Among the world-beating products we have
developed and made are the world’s strongest insulators for UHV (1 million volts) power
transmission and the bushings using the world’s largest hollow insulators. We also boast
the world’s largest production capacity—which is just as well, because our products are
used in at least 100 countries. Backed by uncompromising quality and advanced
technology, our products continue to make power supply safe and secure.
Insulators for
power transmission
Here at NGK Insulators, we
produce an extensive line-up of
multi-functional insulators that
are resistant to dirt and lightning
damage.
We constantly seek to innovate,
and have succeeded in making
our insulators more compact
without compromising strength
or isolation capacity. Thus, our
suspension insulators for UHV
power transmission are only
40cm in diameter but can
withstand a load of 77 tons.

CORPORATE PROFILE
Insulators and equipment for substations
NGK hollow insulators, support insulators, bushings,
isolators and other transformer devices are used to isolate
power lines from equipment and the transformer building. In
fact, our technological capabilities enabled us to make UHV
gas bushings some 11.5 meters long—the largest porcelain
products in the world.
Equipment for power transmission
We manufacture devices to prevent power
outages when something happens to
transmission lines. In particular, our line
arresters, which have built-in functional
ceramic (zinc oxide elements), make a huge
contribution to blackout prevention by
selectively discharging the large fluxes in
current caused by lightning strikes.

NGK Insulators’ fine ceramic technology
Appreciated by worldwide automobile manufacturers
HONEYCERAM is a ceramic catalyst carrier, which neutralizes the harmful substances
in automobile exhaust. HONEYCERAM’s honeycomb design results in a large surface
area — the area that comes into contact with exhaust — with a very compact installation.
In fact, the coating of gas-purifying catalyst total surface on a palm-size HONEYCERAM
would cover an area equivalent to two soccer grounds.
For maximum exhaust gas cleaning efficiency, HONEYCERAM was designed with
minimum weight and wall thickness: the 0.05 mm walls minimize loss of engine power.
The remarkable properties of cordierite ceramics — of which HONEYCERAM is —
enable it to withstand the high temperatures as well as sudden and sharp temperature
changes of exhaust gas with ease.
