Cut out fuse

The cut out fuse is installed on the branch line of the 10kV distribution line, which can reduce the power outage range. Our fuse tube for dropout fuse is used to manufacture this product.

Medium voltage fuses

The product can be used in system with AC50Hz and rated voltage of 10KV,used together with other protection facilities(such as loading switches).It can protect electric transformers and other electric facilities against overloading or circuit break.

Lightning arrester

This product is a high-voltage full-range current-limiting fuse, suitable for indoor AC 50Hz, rated voltage 40.5kV power system, as the overload and short circuit protection of power transformers and other power equipment.

40.5KV fuse

for wind power protection

Epoxy wound pipe is used to make this product. Lightning arresters are used to protect the insulation of AC power transmission and transformation equipment from lightning overvoltage and operating overvoltage damage.

Fuse Link

The fuse link is characterized by perfect time current characteristics, high mechanical strength, and reliable arc-extinguishing performance, etc. The vulcanized fiber tube has good electrical insulation properties, arc resistance and arc extinguishing properties.

Car fuse

Photovoltaic fuse

Melamine glass cloth laminated tube has excellent arc extinguishin performance, high temperature resistance.Widely used in automotive fuses, photovoltaic fuses, etc.

On-load tap changer

The characteristics of the on-load tap changer are small size, light weight, simple structure and convenient maintenance, which reduces the operating cost of the transformer.

Melamine glass cloth laminated tube has excellent arc extinguishin performance, high temperature resistance.Widely used in automotive fuses, photovoltaic fuses, etc.
