Composite Station Post Insulator

Composite Station Post Insulator


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.
