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.
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.
