Composite Insulators

In the past, insulators were mostly used for telephone poles. With the development of science and technology, they gradually developed to the point where a lot of disc-like insulators are hung at the end of the high-voltage wire connection tower, which is to increase the creepage distance. They are usually made of glass or ceramic and are called insulators.Insulators play two basic roles in overhead transmission lines, that is, supporting wires and preventing current from returning to the ground. These two roles must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise, the service and operating life of the whole line will be damaged.

Insulator in overhead transmission lines with two basic role, namely support wire and prevent the current back, these two functions must be guaranteed, insulator should not change due to environmental and electrical load conditions lead to various electrical and mechanical stress and failure, or else there won't have a significant role in the insulator, will damage the whole line of use and operating life.

Composite insulator this product adopts the overall rod design, compact structure, high quality, weight is 1/10 of the same grade of porcelain and glass insulator, transportation and installation is very convenient. Suitable for dirty areas, high mechanical tensile load, long span and compact lines. The pollution lightning voltage is 30%-50% higher than that of porcelain and glass insulators of the same grade, and the performance is stable at -60℃~+200℃. The use of non-breakdown design, operation without measuring the zero value.
