Feature

Compared with traditional ceramic insulators, the use of polymer/silicon rubber-based insulators has several advantages, such as light weight, non-brittleness, hydrophobicity, resistance to ozone and UV radiation, seismic shock resistance, self-cleaning properties, and damage resistance.

The exterior shed is moulded in rubber using the latest state-of-the-art injection moulding machines from .

End fittings for connection to support structures or conductors are made of malleable cast iron and are suitably hot IP galvanized. O Metal end fittings are crimped on a microprocessor controlled automatic hydraulic crimping machine. O Various types of long rod insulators available with voltage ratings from 11 kV to 33 kV ball and socket; tongue and clevis type end fittings.

Structural Features

The core wire is the insulating part of the composite insulator, made of fiberglass rods and designed to ensure the necessary mechanical properties. The fiberglass rod used to make silicone rubber insulators is a core material manufactured through a protruding process using boron-free ECR grade fiberglass with the required mechanical and electrical properties.
