Composite 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 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.
