A surge arrester is a protective device for limiting voltage on equipment by discharging or bypassing surge current. MOA ceramic or polymer shell is applicable to power generation, transmission, power conversion, and distribution of AC 220kV and below. They are mainly used to maintain the amplitude voltage of lightning impulse and the specified level of switching impulse withstand voltage.
The Drop Out Type Surge Arrester is an innovative and essential lightning protection device designed to safeguard electrical distribution systems. This type of surge arrester is distinctively installed on a drop-out mechanism, following the modification of a distribution type zinc oxide arrester.
Surge arrester is the most advanced over-voltage protector in the world.lts core element, metal oxide varistor (MOV).Massive productions of surge arrester(MOA),either with porcelain or polymeric housing, are suitable in the systems ofpower generation, power transmission, power transformation,and power distribution under AC 220kV and below.
