Porcelain Silicone Rubber
Clean

Polluted

Why Composite Insulator
- Anti-Pollution Flashover
Surface
of silicone rubber
is hydrophobic
and transfers this
property onto
polluted layers on
the surface.
Surface
of porcelain
is hydrophilic
the continuous wet conductive contaminating layers can be
easily formed on the surface, which can cause the flashover.

8. Why Composite Insulator
- Environment Change Influence in the Safety of Grids

The changing weather is not only affecting people heath but also affecting power grids.

The silicone rubber has excellent hot melt property and hydrophobicity. During
storms, ice slush will not formed.
Why Composite Insulator
- Anti-Ice Flashover

Bullet Shooting Test on CB
with Porcelain & Composite Hollow Core Insulator
Composite: no explosion, only with a bullet hole
Porcelain: exploded immediately
S/S after earthquake
Composite: remain normal operation
Porcelain: brittle fracture failure & damage
Note：
All Shemar supplied composite insulators (over 600Nos.) were in
safe operation during Wenchuan ,Yushu & Lushan etc. Earthquake
in China,
Why Composite Insulator
- Explosion & Brittle Fracture Failure Greatly Improved

Why Composite Insulation to be the Future
of Power Grids
New designed Composite Insulated OHTL & S/S,
 require min. ROW & Land
 more stable, reliable and economic
 minimize the influence in the environment & society
 feasible to upgrade the existing OHTL to increase the transfer capacity

Nordic TSOs in Sweden, Finland and Norway developed a compact transmission line for 400
kV. With CICA solutions, and the shield wires be replaced by polymer surge arresters. The
compact line is less than 50% of the height and width of a conventional line, as well as less
than 50% EMF radiation. In addition the reliability is increased

TSO: Austrian Power Grid AG, Austria
Different approaches can be used to
strengthen the transmission grid.
Extraordinary long procedures for
planning and authorization of new lines,
often over decades, are no exceptions in
many countries.
Upgrading of existing Overhead Lines
(OHL) could be a method to overcome
such hurdles.
Many TSOs follow the principle
“optimization before extension”.
Upgrading is one such method and
facilitates the prevention of building new
OHL.
 reconductoring
 Thermal rating
 Increasing voltage
 AC to DC

Advantages of upgrading an existing OHL are mainly observed in the following:
 use of existing routes and corridors
 use of existing structures, foundations, conductors as much as possible
 no new landowners and communities are concerned
 normally faster approach than a new line
 very little or even no influences on the environment
 in general high acceptance
 cost efficient solution compared to a new line

Spanish TSO REE decommissioned an old 132kV OHTL Mudarra-La Olma (20km) in 1985, taking
advantage of the existing right-of-way of this 132kV OHTL, to construction a new CICA designed
OHTL which upgraded up to 220kV, The new designed 220kV CICA typical tower height is just under
26 meters with 6 meters separating the left from the right conductor, the line offers excellent use of
the existing corridor.

 Project: Stevin (extension of the 380 kV grid to the coast), CICA solution OHTL is used)
 An old line (150 kV) to the left and the new line 380 kV to
the right constructed with towers of approximately the
same height.
 The existing ROW of 150kV OHTL is sufficient to the new
CICA designed 380kV OHTL.

With the development of the economy & society, new buildings &
infrastructure built near or under the OHTL, there is big risk for the normal
operation of transmission lines and dangerous to the human activity nearby
the transmission line. With the CICA solution on the existing tower, height of
conductor can be raised.
