Economic and useful


HRW12 series drop fuses are widely used in the primary side of 15-36kV distribution line transformer as backup protection and for system and equipment switching operation. These series are installed on the 15-36kV distribution line branch line, which can reduce the power outage range, because it has an obvious disconnection point and has the function of isolation switch, which creates a safe working environment for the maintenance section of the line and equipment.

Shutdown and power transmission operations are allowed even in the case of load.

   Our products are reasonable in design, safe and reliable, easy to use, and its performance conforms to the national standard IEC 60282-2.
