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.
The Arrester Wildlife Protection Cap, also known as a bird-proof cap, rainproof cap, or cover, is a specialized protective device designed to prevent wildlife from making accidental contact with the top end hardware of surge arresters. This crucial safety measure helps protect both wildlife and electrical infrastructure from potential harm and disruptions.
Overvoltage protection is essential for various applications in low voltage lines, including electricity distribution, consumer in-house supplies, and distribution transformers. This protection is crucial to guard against lightning strikes and switching actions. The most effective method for safeguarding electrical equipment is the installation of surge arresters. These devices, placed close to the electrical equipment, provide reliable protection and ensure the longevity and safety of the system.
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.

A Surge Arrester Disconnector is a device designed to disconnect an arrester from the system in the event of arrester failure. Its purpose is to prevent a persistent fault on the system and provide a visible indication of the failed arrester. The thermal explode disconnector complies with IEC 60099-4 standards. The thermal explode type disconnector operates only if a power frequency fault current flows through the device during a failure. It does not activate from surge currents.
