The drop fuse is composed of three parts: insulation support, dynamic and static contact and fuse tube. The static contact is installed at both ends of the insulating support, and the fuse tube is composed of the inner arc cancellation tube and the outer phenolic paper tube or the reduced glass fiber cloth tube. How it works

The drop type fuse is suitable for the power system with frequency of 50HZ and rated voltage of 35KV and below. It is installed on the high voltage side of the distribution transformer or the main line of the distribution. The main function is not high protection performance requirements, it can be used with isolation switch, instead of automatic air switch; It can also be used in conjunction with load switches to replace expensive circuit breakers. It also has short circuit protection, overload and isolation circuit.
