Henan Jingwei Electric Power Technology Co.,Ltd.

Description
Features:
- Light weight, small size, easy for transportation and installation
- High cantilever strength, good performance for seismic shoc  resistance, and brittle fracture resistance
- Super performance for anti pollution
- Low maintenance cost  

Structure:
Consist of silicone rubber housing, fiberglass rod and end-fittings. For system voltage 220kV and above, recommend corona rings for one or both ends. Also it’s available if some applications required corona rings for lower system voltage. 
 
Production Process: 
Injection process, which keep the core and housing strongly bonded without any space, with best internal insulating performance, and could avoid the puncture occurred on interface.
