Zinc Oxide Blcok for Lightning Arrester

Zinc Oxide Blcok for Lightning Arrester
Product Detailed
Zinc Oxide Block is the main core of Lightning Arrester.We supply the diameter from 28mm to 88mm.

Zinc oxide Block for Lightning arrester is non-linear resistor utilizing as semiconductor electrocnic ceramic element mainly composed of zinc oxide and its resistance change as a function of applied voltage.It's called varistor or mental oxide varistor, just as it is sensitive to voltage's change.
