Polymer Post Insulator

This new generation of Polymer Insulator characterized with: Small Light High mechanical strength High performance against pollution No need zero value detection Easy installation Less maintenance The polymer insulator produced by our company has applied whole injection technique, the combination of hardware fittings and glass-fiber core are employed compression technique, which is equipped with fully-automatic detection damage inspection system. The terminals of hardware fitting have four layer sealing to eliminate the key-problem influencing the reliability of composite insulator-interface brittle fracture. Therefore, advanced equipment and strict production procedure ensure our polymer insulator meet the technical requirements of GB/T19519-2004 and IEC61109. Suspention type end fittings: O types, Ball & Socket type, clevis type tec weather aging test: 5000 hours type tested Post type insulator for switch, with material of silicone rubber. Small and light. Rated voltage from 11kV to 38kV. Application: for high voltage switches
