Basic overview of insulators
- Dec 28, 2016 -

Insulator is a special insulation control plays an important role in overhead transmission lines. Early insulators used for poles, slowly developed in the high-voltage wires hang up one end of a lot of disk-shaped insulator, it is in order to increase the Creepage distance, usually made from glass or ceramic, called insulators.

Insulators for overhead transmission lines plays two roles, supporting current and prevent the wire back, which must be guaranteed, insulators should not environmental-load conditions change and various electrical and mechanical stresses caused by failure or insulators would not have a significant role, it will damage the use and life of the whole line.
