33kV Polymeric Insulator is frequently employed as an insulator in electrical applications because of its remarkable electrical, mechanical, chemical, and thermal characteristics. Electric insulators made of polymers have good mechanical qualities, high resistivity, low dielectric loss, and high dielectric strength. 33kV Polymeric Insulator includes a screw that is used to secure the insulator to the cross-arm, located on the bottom side of the fitting. In order to secure conductors, header fittings often have a groove form. This is safe to use.
