HY5WS

Product Features

1. Strong are extinguishing ability, reduce the damage of arc to equipment
2. that structure is simple and mainly consist of an insulator, a contact, a fuse tube and other components,
Relatively simple, easy to manufacture, install and maintain.
3. convenient and safe operation

Product Advantages

1. Reliable short-circuit protection function: When overload or short trouble occurs in the circuit and the current through the fusible cutout exceeds the fusing current of the fuse, the fuse will fuse quickly to cut off the circuit and protect the electrical equipment from overload.
Load and short circuit current damage.
2. Good environmental adaptability, able to adapt to various outdoor harsh climatic conditions, such as high temperature, low temperature, humidity, sandstorm and other environments, to ensure the positive power system Constant operation.

Functional Features

1. Power line protection: It is widely used in the overhead distribution transmission line of 10 kV and below as the short circuit and overload protection equipment of the line. When the line fails, the drop-out fuse will cut off the fault current quickly to prevent the expansion of the fault range and ensure the normal power supply of the non-fault part of the line.
2. Distribution transformer protection: It is installed at the high voltage side of the distribution transformer. When the short trouble occurs inside the transformer or the external circuit fault affects the transformer, the fuse will be blown in time to cut off the power supply and protect the transformer from damage.
3. Protection of small electrical equipment: For some small high-voltage electrical equipment, such as capacitor banks, pole-mounted switches, etc., the drop-out fuse can also be used as a short-circuit and overload protection device to ensure the safe operation of the equipment.
