Metal Oxide Arrester

This series of MOA applies to the over voltage protection of AC transmitting, power distribution equipments. The technical quality satisfies the requirements of GB11032-2010、JB/T8952-2005.

YH10CX series of line MOA with series gap
This series of products is used to avoid the over voltage of lightening for insulator in AC transmitting line. Lightning arrester and insulator are series-parallel installed. When lightening over voltage happens, the lightning arrester will work at first to absorb the energy of over voltage. It will raise the lightning withstand level. It applies for the area where the lightening is strong and earth resistivity is high. The advantage of this product is that when there is no lightening, it can be part with the system because the gap, so there will be no problem of lightning arrester aging.

YH10WX series of line MOA with no gap
This series of products is used to avoid the over voltage of insulator in AC transmitting line. When influenced by distance and lightning arrester of series gap can not be used, line MOA with no gap is suggested. The feature of this product is good dispersion of residual voltage, good response. The main parameter is given in the next table.

YH2.5WD MOA for protecting motors
This series of products applies for the over voltage protection of AC motors

YH5W series of MOA for protecting electric generator
This series of products applies to the over voltage protection of AC motors.

YH1.5W series of MOA for protecting the neutral spot of transformer.
This series of products applies to the over voltage protection of neutral spot of transformer

YH5WT series of MOA for electric railway tracks
This series of products applies to the over voltage protection of electric railway tracks.
