33kv Polymeric Zinc Oxide Gapless Surge Arrester/Lighting Arrester for Distribution

Product Description

SURGE ARRESTERSApplication:
Massive productions of surge arrester (MOA), either with porcelain or polymeric housing, are suitable in the systems of power generation, power transmission, power transformation, and power distribution under AC 220kV and below. They are mainly used to keep the amplitude of lighting impulse withstand voltage and switching impulse withstand voltage to the prescribed level.
Keystone:
Surge arrester is the most advanced over-voltage protector in the world. Its core element, metal oxide varistor (MOV).
Under the circumstance of normal operating voltage, the current through the surge arrester is just on microampere degree. When suffered from over-voltage, the surge arrester' s excellent non-linear characteristic will make the current through the surge arrester increase to several thousand amperes. And the surge arrester will be under the circulating state and release over-voltage energy so as to protecting the power transmission equipment against the damage caused by the over-voltage.
Condition of Use:
1. Ambient air temperature within the range of -40ºC to +40ºC;
2. Altitude above sea level not exceeding 2,000m;
3. Frequency of the A.C. power supply being 50Hz or 60Hz;
4. Power frequency voltage applied continuously between the terminals of the arrester not exceeding its continuous operating voltage:
5. Maximum wind speed not exceeding 35m/s:
6. The earthquake intensity not exceeding 7 degrees.
Characteristics:
-Low residual voltage
-Long protection distance
-High energy input capacity
-Stable volt-ampere characteristic even after multiple strokes
-Proof against ageing
-Explosion and shatter-resistant design
-Pollution resistant and UV-stable
-Housing resistant to rough handling
-Maintenance free
-Stable against shock and vibration
-High mechanical resistance
Technical Standard:
The technical performance of the products is in confirmed to IEC60099-4.
