Metal oxide varistor MOV is the heart of an arrester. Metal oxide varistors MOVs produced by metal oxide varistor manufacturer TGE have advanced technical parameters and stable quality, E.g. Residual voltage change is within 1% after 2 impulses 100kA 4/10 µs test for TGE D36 MOV, And Residual voltage change is within 3% and Ure's change is within 1% after Qrs 0.4C charge test with 8/20 µs waveshape for TGE D36 MOV.
TGE's MOV should be widely used in Distribution, Station, and Line surge arresters to protect the stability of power energy, It is also widely used in new energy fields, such as photovoltaic power stations, wind power stations, etc.
