230KV 120KN composite Suspension insulator
230KV 120KN composite Suspension insulator use of gradient rings is required, to reduce electrical gradient along the insulator and around the end fittings. The gradient rings are made of aluminum alloy. Gradient rings do not substitute usual protection against short circuit currents. 230KV 120KN composite Suspension insulator consists of FRP core, silicone rubber shed, housing and metal hardware.
230KV 120KN Composite suspension insulator for applications up to system voltages of 230kV, providing a reliable solution for power utilities with installations in high pollution environments worldwide.
