Polymer Insulator
General
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.
