  • SMICO

Availability:

The gapless metal-oxide surge arrester (MOSA) is the most advanced overvoltage protector in the word. Due to the varistor of core component 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 over voltage,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.

Advantage

1、Low residual voltage

2、Long protection distance

3、High energy input capacity

4、Stable U-I characteristic even after multiple strokes

5、Proof against ageing

6、Explosion and shatter-resistant design

7、Pollution resistant and UV-stable

8、Housing resistant to rough handling

9、Maintenance free

10、Stable against shock and vibration

11、High mechanical resistance
