Polymeric

Insulators

ENERGY PRODUCTS DIVISION

Insulators

Insulators are devices which are used on electricity supply networks to support, separate or contain

conductors at high voltages.

Insulators have the dual functions of mechanically supporting aerial conductors while also providing

adequate electrical insulation between the energised conductor and the supporting pole or structure.

Insulators are used in electrical systems and are designed to accept Cantilever or Tension loading.

Polymeric Insulators

Polymeric Insulators consists of:

A glass fibre reinforced resin core to provide the

mechanical strength, while resisting the electrical stress

Elastomer sheds to provide the required creepage and

stress reduction to with stand the stresses prevailing on the

system. Two commonly used material are silicone rubber

and Ethylene Vinyl Acetate(EVA)

A major advantage of polymeric insulators is an upto 70%

reduction in weight when compared to porcelain insulators

which can be used to redesign and bring down the weight of

the entire structure ensuring cost reductions.

Hollow Core Insulators

Raychem's Hollow Core Insulators consist of a glass fiber-reinforced epoxy tube,

aluminum-casted flanges and silicone rubber housing.

Application:

Bushings for Transformers, Walls and Dead Tank Breakers

Grading capacitors, chamber and support insulators for life tank breaker

Current and Voltage Transformers in oil and SF6

Cable Terminations

Surge Arresters

Features Benefits

Low weight Easy handling during installation on site and in the factory,

simple support structures, low transportation cost

Composite structure Provides explosion safety for personnel and equipment in case of

internal fault ( power arc & overpressure) & high safety in seismic areas

Silicone housing Improves insulating behaviour at simultaneous stress of both, moisture

and pollution . High UV resisitance. No maintenance - no cleaning or

greasing - due to the hydrophobicity transfer.

Flexible sheds Reduces risk of breakage during transport and assembly makes

equipment vandalism proof
