33kv Station Class Surge Arrester Gapless Metal Oxide Zinc Disc Arrestor

Product Description

Superior Characteristics of Metal-oxide Zinc Arresters

1. Large discharge capacity 
It mainly embodies at the capacity of absorbing various lightning overvoltage, power frequency transient
overvoltage and switching overvoltage. Line discharge level, energy absorption ability, 4/10μs high current
impulse withstand, 2ms rectangular current impulse withstand all achieve to the international lever. 

2. Reliable protective feature
It has a good non-line volt-ampere characteristic with metal-oxide zinc core, under normal working voltage,
there is only a few hundred microamperes of current passing through, which decides it's easy to build the
gapless structure to get a good protective capacity. The current of passing the metal-oxide zinc core rapidly
expands when overvoltage immerses, processing overvoltage amplitude firstly, release overvoltage energy.
Then metal-oxide zinc core recovers high resistance to ensure the electric system working normally.

3. High sealing and anti-pollution performance
Utilize premium gas tightness composite material, compacted sealing circle, increasing sealant to guarantee
metal-oxide zinc arrester working stably. Otherwise, metal-oxide zinc arresters have good anti-pollution
capacity, being more and more popular in the market.
