Yuanky Metal-Oxide Low Voltage Arresters

Yuanky Metal-Oxide Low Voltage Arresters

Short Description:

The integral disconnector disconnects the arrester from the net work if an overload occurs, caused, for example, by a lightning strike in the vicinity impermissible voltage excursion in the systerm.  If this happens the rating plate on the underside of the arrester dislocates and remains dangling from a holding wire.  The ground connection itself remains securely in position. This arrangement ensures that when the arrester disconnects, the ground connection line cannot penetrate or dangerous parts of the overhead system.  The rating plate is large and is reflective on the reverse, so the defective arrester is easily spotted.  All terminals are made of high-grade steel and connect to aluminum or copper without corrosion problems.
