What is an insulator?

Insulators commonly known as porcelain, it is used to support the wire insulator, the general overhead line power engineering will be used, insulators are also a special insulation control, can be in the overhead transmission lines play an important role. In the early years, insulators were used for utility poles and slowly developed at the end of a high-voltage wire connecting tower. A lot of disc-shaped inserts were made. It was designed to increase the creepage distance, usually made of glass or ceramic. Insulators should not be due to changes in environmental and electrical load conditions caused by a variety of electromechanical stress failure, otherwise the insulator will not have a significant role, it will damage the entire line of use and operating life.

In the early years, insulators were used for utility poles and slowly developed at the end of a high-voltage wire connecting tower. A lot of disc-shaped inserts were made. It was designed to increase the creepage distance, usually made of glass or ceramic. Insulators play two basic roles in overhead transmission lines, namely, supporting the wires and preventing the current from returning to the ground. These two functions must be ensured that the insulators should not fail due to various electromechanical stresses due to changes in environmental and electrical load conditions, Otherwise the insulator will not have a significant role, it will damage the use of the entire line and operating life.
