Product Description

20KV Polymer Housed Metal Oxide Surge Arrester Without Gaps

Product Description

PRODUCT DESCRIPTION

The introduction of function:

When there are lightning over-voltage or switching over-voltage in the system,the metal-oxide varistors have low resistance and the harmful over-voltage energy is discharged into earth, so that the over-voltage is limited to be lower than the allowable value, thereby reliably protect the electric equipment. When the system is under normal operation voltage, the metal-oxide varistors of the surge arrester have high resistance and the leakage current passing through the surge arrester is very small(Microampere level), so that the electric equipment is reliable in services.

The common parameter of the 20KV arrester:

Protective object	Type of an arrester	System nominal voltage (KV)	Rated voltage of an arrester (KV)	Continuous operating voltage of an arrester (KV)	Direct-current reference voltage at 1mA D.C. (KV)≥	Lightning current impulse residual voltage (KVP)≤	Under continuous operating voltage resistive current (μA)≤	2ms rectangular current impulse withstand (A)	High current impulse withstand (KA)
