FSC-12 High Voltage Outdoor Expulsion Dropout Fuse Cutout
Description
Fuse cutouts are connected with incoming feeders of distribution transformers or other distribution equipments. It is primary applied to protect transformers or lines from short circuits and overload when there is a lightning impluse. It can reponse in a rapid and in time status and realize protection of whole system.
This dropoout is composed of insulator supports and a fuse tube, static contacts are fixed on two sides of insulator support and moving contact on two end of fuse tube. The interior of fuse tube is the extinguishing tube, and exterior is made of phenolic compound paper tube or epoxy glass.
We produce the fuse cutout up to 38kV with both polymer and porcelain housing. Strict inspection shall be made during every process of the fuse cutout assembly and complete routine test according to applicable IEC standards shall be performed on the fuse cutout before ex-works to ensure its quality.
Environmental Conditions
1. Ambient temperature: not higher than +40 ºC, not less than -40 ºC
2. Altitude: not exceed 2000M
3. Earthquake intensity: not more than 8 degree.
4. Wind pressure:≤700pa
5. No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration
Product Features
1.Low minimum breaking current,low power losses and low arc-voltage.
2.High breaking capacity and effective short-circuit prospective current limitation.
3.Fuses are the fatest overload protection devices for high short-circuit currents.
4.Applying the superior insulating material,large creepage distance and suitable for different environments.
