Composite Suspension Insulators are electrical components designed specifically for suspension applications in high-voltage electrical systems. They consist of a core material made of insulating silicone rubber or other polymer materials, surrounded by a weather-resistant, flexible outer shell. The suspension insulators are suspended from overhead power lines and provide electrical insulation between the conductor and the support structure.
Composite Suspension Insulator voltage class:
11kV, 12kV,15kV,24kV, 33kV, 36kV,69kV, 110kV, 132kV, 138kV,169kV, 220kV, 245kV, 330kV, 400kV, 420kV, 500kV 750kV
