Metal Oxide Varistors Used in Industrial Components

TGE can provide MOV with excellent protection characteristics for arrester products used in high temperature and high humidity environments such as cable joints, photovoltaics, and wind power.
TGE can be used as a heavy-duty surge arrester MOV for overvoltage protection in petrochemical and metallurgical industries
The metal oxide varistor manufacturer TGE can provide large-capacity MOV for surge arresters for motor and shunt capacitor overvoltage protection. Correct metal oxide varistor sizing is essential for these applications to ensure reliability.

What does a metal oxide varistor do ?

A metal oxide varistor, also known as MOV blocks, is an electrical component used to protect electronic devices from overvoltage surges. It acts like a voltage-controlled switch, instantly changing its resistance depending on the applied voltage. When a surge occurs, the MOV absorbs the excess energy and diverts it to the ground, safeguarding sensitive equipment and preventing damage. MOV blocks are widely used in power supply systems, electrical distribution networks, and electronic devices to ensure reliable and safe operation. Metal oxide varistors (MOVs) are commonly used in industrial components as a type of surge protection device. They work by limiting the amount of voltage passing through a circuit, protecting it from damage caused by power surges or voltage spikes. The varistors are made from zinc oxide and other metal oxides, and when the voltage rises above their rated level, the varistors quickly reduce the voltage to a safe level, providing surge protection and circuit stability. MOVs are available in many different sizes, voltages, and current ratings, allowing them to be used in a variety of industrial applications.
