surge arrestor 12-42kV
Detailed Product Description
This surge arrestor is for 12-42kV include distribution type, station type, capacitive type and many other specification.
Distribution MOA are mainly used for the portion of 12-42kV distribution transformerbox type stationcable headpole switch and so on against damage from atmospheric of power.
Station MOA are mainly used for the protection of power station and transformers against damage from the atmospheric overvoltage and the transient overvoltage.
Capacitive MOA are mainly used for restraining re-burn overvoltage raised by vacuum switch or less-oil switch when switch on or off capacitors, and also for the protection of the
