3kV 5kA Metal Oxide Rheostat Mov Block Surge Arrester For Overvoltage protection

3kV 5kA Metal Oxide Rheostat Mov Block Surge Arrester For Overvoltage protection

A complex structure of micro varistors consisting of Zinc oxide grains and surrounding high-resistance grain boundary layers, connected in series and parallel. Therefore, if the size of the Zinc oxide grains is the same, the varistor voltage is proportional to the thickness and the surge withstand capability is proportional to the cross-section area of the MOV

Compared to ordinary resistive elements, MOVs have a very large non-linear voltage-current characteristic, so they act as insulators in areas where the applied voltage is small, and as conductors in areas where the voltage is large, such as in lightning surges. This makes it possible to safely protect equipment from lightning surges.

Features

The MOVs used in surge arresters and surge protective devices (SPD) are manufactured under strict quality control and have excellent non-ohmic properties, high surge withstand capability and longer service life.

Excellent non-ohmic propertyWhen an excessive surge is applied to a MOV, the terminal voltage of the MOV is kept as low as possible to protect electronic equipment and power facilities. High surge withstand capabilityUniformly current flow in an MOV due to high homogeneity of daily improved ZnO ceramics and high collaring materials having high insulation are realized. Long service lifeHigh reliability under the condition that system voltage is constantly applied. Wide range of products A wide range of AC and DC products, from low to high voltage, are available to meet a wide range of needs. Our MOVs satisfy international standards related to surge arresters, SPDs and MOVs(IEC, IEEE, UL etc..)
