2022 wholesale price 3 Phase Switch Disconnector - Fuse Cutout Switch Hrw-15-100(200)10kv,15kv,25kv,27kv,33kv,38kv Iec&Ansi Standard Medium And High Voltage Dropout Fuse Cutout – EC Insulators

Description

Drop fuse cutouts and load switching fuse cutouts are for outdoor used high voltage protective device. To be connected with in coming feeder of distributing transformer lines it mainly protect transformers or lines from short circuit and overload, and on/off loading current.
Drop out fuse cutout is composed of insulator supports and fuse tube, static contacts is fixed on two sides of insulator support and moving contact is installed on two ends of fuse tube. Fuse tube is composed of inside arc-extinguishing tube,outer phenolic compound paper tube or epoxy glass tube.
At normally working via fuse link tightened the fuse tube is fixed to form up of close position. In case system current faults, faults current result in fuse melt immediately and take place electric arc, which let arc-extinguishing tube being heated and explode a lot of gas. This will produce high pressure and blow off the arc along the tube.After fuse link melt, moving contact has no lightened strength again, mechanism is locked and fuse tube drop out.cutout now is open position.

Features

1.Fuse holders are interchangeable with most other manufacturers within the same voltage class
2.Inner core is made from Epoxy Impregnated fiber Glass Rod
3.All hardware is made from non-corrosive stainless steel components silicone rubber for the housing with its excellent Hydrophobisity helps ensure the switch does not accumulate contamination. High resistance to Ozone and UV.
4.Larger leakage distances add longer life to the switches
