Composite insulator

Gegeral

Composite insulator composed of three parts of an insulating rod, silicone rubber polymer-housing and connecting fittings on both ends.

Insulator core rod is the short form of epoxy resin glass fiber core, it is the skeleton of composite insulator, plays multiple roles in supporting housing, endothelium insulation, connecting the fittings of both ends, as wehemical resistance, and good resistance to bending fatigue, creep and impact. Silicone rubber mainly plays a role in protecting rod, shielding rain and snow, increasing the cree page distances and external insulation of the products, it is made from the main part of polymer s ilicone rubber, with fire retardant, inhibitor, coupling agent and so on, through high temperature an d pressure, then vulcanization. It has good hydrophobicity and migration, as well as good corrosio n resistance, aging resistall as withstand mechanical loads ect., with very high tensile strength, us ually above 600Mpa,it’s twice of common steel, 5 to 8 times of the porcelain material and has go od dielectric properties and cnce, electrical insulation properties. And it has high pollution flashover voltage and resistance to crushing performance, voltage well-distributed, compared with porcelain kinds under the same condition, its flashover voltage is more than twice of porcelain kinds.

The composite insulators which manufactured our company using the fittings made from special st eel, both ends of the fittings designed based on the principles of labyrinth, multilayer protection, g ood sealability, solved the most critical issue of insulator --- Interface electrical breakdown. Connec tion between fittings and the core rod using the computer-controlled coaxiality constant pressure cri mping process the most advanced in the world, and equipped with fully-automatic acoustic emissio n crack detection system, ensured the reliability and stability of the connection between fittings and the core rod. The core rod using ERC high temperature acid-resisting rod, the interface of core r od and the silicone rubber coated with special coupling agent. The silicone housing using disposab le integral shaping process under high temperature and pressure. with the second-stage vulcanizati on of computer monitoring, extending the service life of the product. Advanced production equipme nt and manufacturing technology, complete testing equipment and testing methods, ensured that th e various technical indexes have reached the relevant standards of national and international, to b e a new generation of insulators of high-voltage power transmission line.
