Product Description

Product Description

Zinc-Oxide arrester is used for protection of outdoor distribution overhead line, transformer, cable connector and electric equipment from being damaged by lightning Impulse voltage and operated over-voltage.
How does ZnO varistor work? ZnO has good non-linear Volt-Ampere characteristics which flowing current is tiny when working under normal voltage. However, when there's over-voltage, its non-linear Volt-Ampere characteristics takes protection effect on leakage and breaking current, as the resistance will decrease rapidly and leak the energy of over-voltage.
Products are completely in accordance with IEC60099-4 standard.
 

 

 

Normal service 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.
