69kv Composite Polymer Line Post Insulator for High Voltage Power Transmission
Product Description
Insulators are used to support and fix the bus and the live conductor, and make the live conductor or conductor and the earth have enough distance and
Insulation.Insulators shall have sufficient electrical insulation strength and moisture resistance.
In order to prevent pollution such as floating dust from attaching to the insulator surface, a path is formed to be broken down by the voltage at both ends of the insulator, namely creepage. Therefore, increasing the surface distance is creep distance, and the discharge distance along the insulation surface is leakage distance, which is creep distance.
Technology characteristics:
Silicone Rubber Housing
Better hydrophobicity
Better hydrophobicity migration performance
Better pollution resistance
Excellent electrical insulation properties
Excellent aging resistance
