Overview

Description:

It is used for overhead power lines with DC or power frequency AC rated voltage below 1000V. It is used for insulation and fixed wire. The insulator used to support the wire can be connected to the wire and the cross-bar tower insulation, which can avoid the sun and rain. Change and corrosion of chemicals

According to its structural type, it is divided into low-voltage pin insulators, low-voltage butterfly insulators, low-voltage bobbin insulators, etc. The ambient temperature of the installation and use location is -40 ° C ~ + 40 ° C, the height does not exceed 1000 m
