Product overview

RW12 series high-voltage outdoor drop fuses are suitable for power systems with a frequency of 50HZ, rated voltage of 35KV or below, mounted on the high-voltage side of the distribution transformer or on the main distribution line.Used for short circuit, overload protection and load current sharing of transformer and line.The product adopts the arc extinguishing principle of self-produced gas longitudinal arc blowing and spring strong arc pulling.The single-end exhaust structure ensures reliable opening of fault current from overload to short circuit.Stable performance, high closing success rate, can significantly reduce the line trip rate and distribution transformer failure rate, reduce the workload of maintenance personnel
