Specifications Zinc Oxide Varistor for Arrester
Dimension:D3,D4,D5,D6,D7,D8.
Used in the zinc oxide arrester
with best price and quality

this Zinc Oxide Varistor is mainly used as the core of metal oxide arrester with the wonderful property.

as A leading manufacturer of the zinc oxide varistor in China, we have Acquired much manufacturing and processing experience. the zinc oxide Varistor is characterized by high level of over-voltage protection due To its low residual voltage and large current passing capacity and is Now widely used in all kinds of surge arresters to provide secure Protection.

the technical data of metal oxide varistor of our company is as below
