MOA of special structure

YH5W-L series MOA with disconnecting devices

This series of products applied to the protection of the over voltage of AC transmitting line, especially in the ungrounded system. When over voltage happens, the lightning arrester runs normally to protect it. After a long time of operation, the varistor shows signs of deterioration or for one-phase grounded, the lightning arrester deteriorates rapidly after a long time of operation at over voltage, the disconnecting device will work to make the lightning arrester stop working.

YH5CB series of series gap over voltage protector for insulating line

This predictor applies for protecting the electric system insulating transmission systems to avoid the atmosphere and operating over voltage. When the appeared lightening voltage is over withstand voltage, the gap discharges electricity, the ZnO varistor absorbs the over voltage energy and limits the voltage of insulator and insulating wire to avoid the flashover of the insulating wire.

YH10W-H series of horizontal MOA (patented product)

This series of products applied to the protection of the over voltage of AC transmitting line. The product adds strengthening coat to raise the flexural strength to avoid the electric change. It applies for areas where the system should be horizontally installed. It is especially suitable to protect the wires of 110kv.

YH5W-D series of overhaul with electricity MOA

This product can be used to electriferous examine and repair of substation feed-in line and overvoltage protection. It can realize electriferous overhaul, replacing and pretest and reduce economic loss because of power cutting.
