surge arrester is a kind of voltage limiter, which is used to protect transmission & distribution equipment ( such as transformer, switch, capacitor, voltage transformer, generator, motor and power cable etc.) from being damaged by over-voltage. As main components of metal surge arrester, our resistors feature non-linear characteristics, good steep slope response, strong current-flow capacity and anti-ageing ability and so on. They greatly improve the protection ability and reliability of surge arrester.
