Technical Standard
The design and test of Metal Oxide Surge Arrester is complied full with IEC99-4.
Sevice Conditions
a) Ambient air temperature within the range of -55°C to +50°C.
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 continuous between the teminals of the arrester
not exceeding its continuous operating voltage.
e) Maximum wind speed not exceeding 35m/s.
f) Earthquake intensity not exceeding 7 degrees.
Advantage
- Low residual voltage- Long protection distance- High energy input capacity- Stable U-I characteristics 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
