Abstract :
The present paper reports the results of a study of mechanical and electrical properties of polymeric insulators. Silicone rubber (SIR), ethylene-propylene-diene monomer (EPDM) and alloys of silicone-EPDM are known polymers for use as high voltage insulators. The result of mechanical measurement shows that the tensile strength, modulus and elongation of blends is enhanced with increase of SIR in the formulation. It can be seen from the results of dielectric behavior measurement that the dissipation factor tan δ and capacity of silicone rubber was improved by the effects of EPDM in blends. The blends of silicone-EPDM show good dielectric behavior compare to silicone rubber at humidity ambient. The new alloy presents excellent dielectric properties in water and humidity ambient in comparison to existing EPDM, silicone and their blends.
