Biref history of GW's composite long rod insulator
Xiangyang Guowang Composite Insulators Co., Ltd. (GW) is located in Xiangyang, China, and has been serving the field of composite long rod insulators for more than forty (20) years throughout world and other countries. In the 1980s GW was the first company who use silicone rubber composite materials for insulators’ housing and sheds. The extensive experience in composite long rod insulator has made GW become the market leader in China and many other countries.
