Zinc Oxide Blocks, Metal Oxide Varistor

We are offering zinc oxide blocks, metal oxide varistor.
metal oxide varistor is a ceramic semiconductor component made of zinc oxide as the main material. Its resistance value varies with applied voltage and presents nonlinear. metal oxide varistor is mainly used to assemble surge arrester of various types and rates and it is the core component of metal oxide arrester. Its quality directly determines the performance of surge arrester.
our company�s metal oxide varistor is characterized by strong galvanization capacity, high protective performance, good nonlinear characteristic, fine appearance, various specifications and so on. the common voltage gradient range is 200-230v/mm. Its diameter and height can be determined neatly according to the customer�s requirements. the varistor�s maximum diameter can reach 138mm and the maximum height can reach 41mm.
