Outdoor Type High Voltage Polymer Electrical Expulsion Dropout Fuse Cutout

Product Description

Principle and Function of T Bar type Fuse Cut Out

The high-voltage drop-out fuse consists of three parts: insulating support, dynamic and static contacts, and fuse tube. The static contacts are installed at both ends of the insulating support, and the fuse tube is composed of an inner arc suppression tube and an outer phenolic paper tube or epoxy glass fiber cloth tube.
Drop-out fuses are suitable for power systems with a frequency of 50/60Hz and a rated voltage of 35KV and below, and are installed on the high-voltage side of distribution transformers or on the main lines of distribution. The main function is where the protection performance is not high, it can be used in conjunction with the isolating switch to replace the automatic air switch; it can also be used in conjunction with the load switch to replace the expensive circuit breaker. It also has short circuit protection, overload and isolation circuits.
Basic Parameter

Description	Fuse cutout is to provide reliable protection for the 10-35KV power distribution line and distribution transformers, it also protects the overload and short circuit, switching on/off the rated load current.
