Electric Thermal 15kv 25 Kv 27kv High Voltage Drop Out Fuse Cutout
In electrical distribution, a fuse cutout or cut-out fuse is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads.
Fuse Cutout is an electric current protector made using this principle.It is widely used in high and low voltage distribution systems and control systems as well as electrical equipment, as short circuit and overcurrent protector, is one of the most widely used protection devices.
Fuse cutout can be divided into high voltage fuse cutout and low voltage fuse cutout according to the service voltage. It can be divided into dropout fuse for protecting transformers and general electrical equipment, for protecting voltage transformers, for protecting power capacitors, ffor protecting semiconductor components, dropout fuse for protecting motors and dropout fuse for protecting household appliances, etc. According to the structure can be divided into open type, semi-closed type, pipe type and jet type fuse cutout
The Fuse Cutout are connected with the incoming feeder of the distribution transformer or distribution lines. These are primary used to protect transformers or lines from short circuits and overloads and switching currents. The drop out fuse unit is composed of insulator supports and a fuse tube, static contacts is fixed on two sides of insulator support and moving contact is installed on two ends of fuse tube. The interior of the fuse tube is the extinguishing tube, the exterior is made of phenolic compound paper tube or epoxy glass.
