Polymer pin insulator

5 (100%) 2 votes

Polymer pin insulator also named as composite pin insulator,is widely used in overhead transmission and distribution line constructions.

XHEinsulator is able to manufacturer a wide range of voltage insulators from 6KV to 1000KV, which is No.1 in China.

Our 750KV large-tonnage insulator jointly developed by our XHEinsulator and Tsinghua University is operated by Lanzhou UHV Transmission and Distribution Company. Ultra-high pressure 330KV, 500KV, large-tonnage composite insulators have been safely operated on 50,000 power grids. The 500kv line includes the Dawu line, the Dabao line, the Baolan line, the Baonan line, the Jinan line, the Nanjing line, and the Gansu province line. The 330KV line includes the Woodlands Line, the Lanbao Line, and the Shanghai-Nanjing Line. The 330KV composite insulator contains the Huijin line; the 220KV line includes the Nantong line, the Guanghui line, the Chengkun line and so on. With the increase in sales performance, 10KV-750KV and other voltage grade products currently have more than 1 million safe operation in major power grids across the country.
