220KV composite disc suspension insulator for high voltage
220KV composite disc suspension insulator for high voltage is one of the elemental insulators of Orient Power, which is an insulator supplier. Except 220KV composite disc suspension insulator, we also produce composite station post insulator, Silicone Rubber Insulator for Electrical Railways, composite tie top line post insulator.
The structure of the 220KV composite disc suspension insulator for high voltage:
220KV composite disc suspension insulator is composed by core, insulator trunk, housing, and end fitting.
220KV composite disc suspension insulator
The material of each part of the 220KV composite disc suspension insulator:
The core of a composite insulator: internal insulating part of a composite insulator which is designed to ensure the mechanical characteristics. The core usually consists of either fibers (e.g. glass) which are positioned in a resin-based matrix or a homogeneous insulating material (e.g. porcelain or resin).
Insulator trunk: Central insulating part of an insulator from which the sheds project (also known as shank on smaller insulators).
Insulator housing: External insulating part of a composite insulator providing the necessary creepage distance and protecting core from the environment
Shed of an insulator: Insulating part, projecting from the insulator trunk, intended to increase the creepage distance (The shed can be with or without ribs).
Interfaces: There are different kind of materials of interfaces, Various interfaces occur in most composite insulators, e.g. between housing and fixing devices, between various parts of the housing, e.g. between sheds, or between sheath and sheds, between core and housing.
End fitting: Integral component or formed part of an insulator intended to connect it to a supporting structure, or to a conductor, or to an item of equipment, or to another insulator
Orient Power focusing on the quality of the high voltage insulators, so we also have all kind of test for insulators: type tests for composite post insulator and we also have the sample tests for HV porcelain station post insulator and design tests for ceramic station post insulator.
