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
High strength pultruded
fibre glass rod
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.

Polymeric Insulator Construction
Composite design
• Lightweight – easy installation
• Vandal and break resistant
• Impact resistant
EVA housing
• High tracking and erosion resistance
• Excellent performance under polluted conditions
• Reduced maintenance costs
Crimp technology
• Maximum mechanical strength without
damaging the fibre glass rod
• Patented crimp
Direct bonding to end fitting
• Ideal moisture barrier, avoids moisture ingress to the
fibre glass rod

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
Easy handling during installation on site and in the factory,
simple support structures, low transportation cost
Provides explosion safety for personnel and equipment in case of
internal fault ( power arc & overpressure) & high safety in seismic areas
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.
Reduces risk of breakage during transport and assembly makes
equipment vandalism proof
