Product Description

Composite insulator is consist of insulation core, silicon rubber sheds and end fittings at both terminals.
As the main structure, insulation core is made of epoxy resin, supporting housing, inside insulation and end fittings at both ends and withstanding mechanical load. The core has good tension strength usually over 600Mpa, which is 2 times than ordinary steel,5 to 8 times than ceramic material, at the same time, the core has good performance at dielectric property, erosion resistance, bending fatigue resistance, creepage resistance and impulse resistance. Silicon rubber sheds mainly protect the core, shield rain and snow, and widen the creepage distance and outside distance
It's made of high molecular polymer silicon rubber, with fire resistant, inhibitor and coupling agent as auxiliaries, the high temperature and pressure vulcanized process provides good hydrophobicity, migratory aptitude, erosion resistance, aging resistance and electric insulation properties. When flashover occurs, it performance good at fracture resistance, distributing voltage averagely and has 2 times electric voltage than ceramic insulator at the same flashover situation.
Composite insulators produced by our Shanghai Powery Industries Co., Lid. Is made of reinforced steel end  fittings with maze design, multilayer protection and good sealing , which have solved (the main problem Insulator that is Interface electric puncture. Connection of core and fittings uses the most advanced coaxial constant pressure crimping  technology, assisted by automatic sound control damage inspection system, assuring the reliability and stability of core and fitting connection. Using ERC high temperature acid-resist bar, surface of the core and silicon rubber is applied with specified coupling agent. The high temperature and pressure disposable molding inspection technology confirms all technical regulations meet domestic and
international standards, making the housing and sheds the newest generation insulator unit in high voltage transmission line.
