The system Voltage of composite hollow insulator is 33kV, 66kV (69kV), 132kV, and 230kV. The mechanical tensile load of composite hollow insulator is 4-20 kN.
The color of composite hollow insulator can be Brown, Gray, Grey or according to customer’s requirement. 
We have full test reports, such as IEC, ANSI, GB, SB.
Composite insulator has strong adaptability of environment ,  the temperature can be from -50℃ to +50℃, altitude from 0 ~ 4000 meters above sea level, and medium & heavy pollution area, or heavy earthquake areas. 
Features of composite hollow insulator:
1) Light weight, small size, easy for transportation and installation
2)  High cantilever strength, good performance for seismic shock resistance, and brittle fracture resistance
3)  Super performance for anti-pollution
4) Low maintenance cost  
Advanced production technology of composite  insulator
Injection process, which keep the core and housing strongly bonded without any space, with best internal insulating performance.
