Advantages Of Adding High Purity Electronic Grade Zinc Oxide Powder To The Arrester

1. Adding high purity electronic grade zinc oxide powder to the arrester will make the arrester more protective.

The silicon carbide surge arrester starts to operate from the gap discharge, so there is a discharge delay phenomenon for the intrusive impulse voltage. Adding electrical stimulation zinc oxide to the surge arrester will prevent the surge arrester from responding without gaps, and can quickly suppress the high voltage. It has good nonlinear resistance characteristics, that is, the resistance is large at normal system voltage, and the resistance becomes very small when lightning strikes or instantaneous inrush current, and the current is quickly led to the ground.

Adding High purity electronic grade zinc oxide powder to the arrester will make the arrester's power handling capability more excellent.

2. High purity electronic grade zinc oxide powder surge arresters have sufficient handling capacity for multiple lightning strikes or shock waves, and zinc oxide components can be connected in parallel to increase the discharge capacity, while silicon carbide surge arresters are difficult to connect in parallel because of the series air gap.

3. Addinghigh purity electronic grade zinc oxide powder to the arrester will improve the pollution resistance.

Because there is no series gap in the zinc oxide surge arrester, there is no uneven distribution of potential on the surface of the insulator. Even if the insulator surface is not damaged, only a small amount of current flows through the stray capacitance between the surface of the bushing and the zinc oxide element, which only increases the leakage current. , So you can improve the non-destructive performance. The silicon carbide surge arrester caused spark discharge due to the contamination of the shell, because it reduced its reliability and shortened its service life.

MST chemical coating grade zinc oxide powder is made by indirect method with high purity and low impurities. It can meet all the requirement of arrester, And keep customers' product quality stable.
