Abstract

Abstract: In this paper, the factory-composited insulators developed by combining the conventional porcelain or glass insulators with high quality RTV coating is proposed to change the RTV coating as a temporary anti-pollution-flashover measure into a permanent one. A new mature external-insulation selection at the design and construction stage of power transmission project is provided, which breaks through the application limit of porcelain and glass insulators used in heavy pollution area as to eventually improve the comprehensive quality of UHV grid. Based on the application experience and test data, the product parameters and design principles of factory-composited insulators are put forward, and the distrust of RTV is clarified.

Key words: UHV, porcelain insulator, glass insulator, anti-contamination-flashover coating(RTV), factory-composited, self-cleaning property, small arc explosion, steep front impulse voltage
