Do You Know Composite Insulators?
- Sep 07, 2018 -

Composite insulator is a special insulation control, which can play an important role in overhead transmission lines.

Composite insulators can be divided into: line composite insulators and power station and electrical appliance composite insulators. It can also be divided into rod suspension composite insulator, needle composite insulator, cross-bearing composite insulator, post composite insulator, wind-proof composite insulator, etc.

Insulators play two basic roles in overhead transmission lines: supporting conductors and preventing current from returning to the ground. These two roles must be guaranteed. Insulators should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions. Otherwise, insulators will not play a major role and will damage the use and operation life of the whole system.
