D42 Series MOV Block for Substation Arrester
The D42 Series MOV for Substation Arrester is designed for heavy-load surge protection in 35kV substations. It utilizes a robust MOV varistor material to absorb and dissipate over-voltage transients, ensuring the safety of your equipment and personnel. It also features a dielectric withstand voltage of up to 50kV, a current rating of up to 100A, and a life expectancy of up to 20 years. As a professional zinc oxide varistor manufacturer, we are sure that with its easy installation and maintenance features, it is the perfect solution for your surge protection needs.
The nouns, parameters and corresponding test methods in this parameter list conform to the standards of IEC60099-4:2014 and GB11032-2020.
The rated voltage, power frequency reference current and power frequency reference voltage are reference values.
The 2ms square wave tolerance value is based on the declared current/2ms repetitive charge transfer charge Qrs=423, if the actual test waveform 2ms current/2mS repetitive charge transfer charge Qrs is not equal to 423, it should be corrected according to the actual 2ms current waveform and Qrs value.
The charging rate of the aging test was 90%.
The number of pulses for the high current withstand value is two.
