Table 8-Main Technical Parameter of Metal-oxide Surge Arrester
(Nominal Discharge Current:10kA)
Application
Protection of medium/ high voltage AC networks against both, multiple atmospheric and switching overvoltages as well as Very Fast Transients (VFT). Suitable for the protection of transformers, transformers in arc furnace applications, cables,generators,parallel to capacitor banks,and railway vehicles.Can be used mechanically as support insulator or as suspension insulator in case of application as line arrester. For indoor and outdoor installation.
Keystone
The metal-oxide surge arrester (MOSA) is the most advanced overvoltage protector in the word.Due to make the varistor of core com-ponent mainly adopt MOSA. Compared with the conventional silicone carbide arrester, this prescription of the product improves greatly the Voltage-Current(U-I)characteristic of the metal-oxide varistor and increased through-current capability at over- voltage so as to bring a radical-changes for the characteristic of the MOSA.
Under the circumstance of normal operating voltage, the current through the MOSA just on microampere degree. When suffered from overvoltage,the MOSA's excellent non-linear characteristic will make the current through the MOSA increase to several thousand ampere,While the MOSA will be under the circulating state and release overvoltage energy so as to protecting the power transmission equipments against the damage caused by the overvoltage.
Usual service condition
a) Ambient air temperature within the range of -55℃ to +50℃.
b) Altitude not exceeding 2000m.
c) Frequency of the A.C. Power supply not less than 48Hz and not exceeding 62Hz.
d) Power frequency voltage applied continuously between the terminals of the arrester not exceeding its continuous operating voltage.
e) Maximum wind speed not exceeding 35m/s.
f) Earthquake intensity not exceeding 7 degrees.

Metal-oxide Varistor
Application
Metal-oxide varistor(MOV) are the core component of an arrester,which are sintering mainly of ZnO powder with addition of Bi2O3, Co2O3,Cr2O3,Sb2O3 and other insition.
As one of the biggest exportor of MOV, XIYA company is a professional manufacturer of MOV of metal-oxide surge arrester.
Adopting the Japanese HITACHI protective technology, we can produce 700 tons ZnO powder ( more than 5 million pieses of D3524MOV)by our full automatic production lines.XIYA company has single passed the KEMA certificate for 27 types metal-oxide surge arrester with our own MOV.
