Insulators are a special type of insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used in utility poles. Later, one end of the high-voltage high-voltage wire connection tower was hung with a large number of disk-shaped insulators. In order to increase the creepage distance, usually made of glass or ceramic, it is called an insulator.

Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulators will not have a significant effect and will damage the use and operating life of the entire line.

Note: High voltage danger! Before performing any work, the current must be cut off, the operating procedures must be strictly observed, and various customized measures should be taken to prevent electric shock and fire accidents.
