Short Description:

Lightning arrester is an overvoltage protector, mainly for the protection of electric power system, the railway electrification systems, communicationsystems in avariety of electrical equipment ( transformer,
switch, capacitor, trapper, transformers, generators, motors, power cables ) from atmospheric over voltage, overvoltage and transient over-voltage such damage, is the foundation of power system insulation coordination.
Metal oxide surge arrester of the core components ( resistors ) with zinc oxide based advanced formulations, has very excellent nonlinear (V-A) characteristics, namely in the normal working voltage, current through the only microampere stage, when subjected to a voltage, current through the moment reached thousands of amperes, make in a lightning arrester on-state voltage, the release of energy, thus effectively limiting
over-voltage on the power transmission and transformation equipment damage.
Traditional silicon carbide surge arrester is because of steep wave discharge delay caused by the steep wave discharge voltage is high, operation wave discharge dispersity in operation wave discharge voltage
high. Zinc oxide surge arrester with good wave response of wave voltage, without delay, the operation residualdepression,no discharge dispersity etc.. The steep wave, wave protection margin is improved
greatly, but also in the insulation coordination, can be steep wave, lightning, operation wave protective margin nearly uniformly, so as to provide the best protection for electric power equipment.
Composite coated metal oxide lightning arrester, adopts integral injection molding, two sealing technology, good sealing performance, explosion proof performance, and can reduce the contamination
resistance free cleaning fog wet hair, electrical erosion resistance, aging resistance, small volume, light weight,convenient installation and maintenance. Porcelain is the set of lightning arrester for the
upgrading of products.
