Metal Oxide Varistors

TGE is a leading high-performance energy block (also called a metal oxide varistor, zinc oxide varistor, MOV blocks, MOV disks) manufacturer, zinc oxide varistor manufacturer TGE was founded in 2002, and the metal oxide varistors can meet the requirements of arresters that cover all voltage levels (3kV-1100kV) in station and distribution system. The MOV's diameter range from 30mm to 128mm and its height range from 6.4mm-44mm. Our technical research and development team has more than 30 years of valuable experience in MOV. We are constantly improving the performance of MOV on the basis of researching IEC60099-4-2014 and IEEE Std C62.11™-2020 standards.

Different Types of Metal Oxide Varistor

MOV Block for Distribution Arrester

MOV Block for Line Surge Arrester

MOV Blocks

The MOV blocks are designed to take excess energy to ground to protect the expensive equipment in distribution and station electric power system, an easier explanation of MOV is that collection of millions of microscopic switches, which is a disk of crystalline semiconductor material made from zinc oxide and the others.

PBT Arrester Core

Arrester Epoxy Glass Wound Core

Arrester Core

In order to meet the needs of different customers, we have developed epoxy glass filament winding cores, which can currently be used as 3kV-72kV arrester cores. We have already OEM 10kV surge arrester bodies for our customers.

What is The Zinc Oxide Varistor Function?

Metal Oxide Varistor

MOV blocks are designed to take excess energy to ground to protect critical equipment in the distribution and station power system, MOV is composed of many small semiconductor switches, MOV can instantly change its resistance to the voltage from high resistance to low resistance if a lightning strike threatens. The high-performance MOV can survive lightning strikes over and over so that it protects power grid equipment for effective long-term operation.

Working of Metal Oxide Varistor

Usually our customers will comment that MOV from zinc oxide varistor manufacturer TGE has good consistency and reliability, we have our own R&D laboratory and R&D team, constantly improving from the details, so we have that really close touch with our R&D team, that allows us to work back and forth to improve our MOV and look at the long-term reliability and long-term longevity of this products. The internal crystalline structure of the MOV is what gives the MOV its electrical characteristics, metal oxide varistor manufacturer TGE controls according to the different needs of customers.

As a metal oxide varistor manufacturer, we will do our best to meet all the needs of customers.
