Insulator introduction
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, it is usually made of glass or ceramic, which is called an insulator.
Insulators play two fundamental roles in overhead transmission lines, namely supporting the conductors and preventing current from returning to the ground. These two functions must be ensured. The insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulator will not have a major effect, which will damage the use and operating life of the entire line.
