I. Overview
ZY-TBP series combined overvoltage protector adopts three-phase four-column combined structure, which is suitable for 35KV and below power systems. It is an advanced protective electrical appliance for limiting lightning overvoltage and operating overvoltage. Mainly used to protect the insulation of electrical equipment such as generators, transformers, switches, buses and motors from over-voltage damage.
