what is"Composite Station Post Insulator"?

Composite Station Post Insulator,Silicone Rubber Station Post Insulator,Polymer Station Post Insulator   

Usage:
Used for outdoor substation, distribution device as well as electrical equipments.
System Voltage: 11kV, 33kV, 66kV(69kV), 132kV, 230kV, 400kV, 500kV,800KV
Specified Cantilever Load (SCL): 2-20 kN
Color: Brown, Gray, or Customer’s requirement
Applicable Standard: IEC, ANSI, or Customer requirement
Applicable Condition: environment temperature from -50℃ to +50℃, altitude from 0 ~ 4000 meters above sea level, and medium & heavy pollution area, especially for heavy earthquake areas.

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.
