Fuse action is achieved by melt blown Yichang high voltage fuses, fuse has a very distinct characteristics, is safe second feature. The melt, its operating current and the operating time of the fuse safety feature that is characteristic of seconds, also called the anti-high-voltage fuse Huzhou delay characteristics, namely: overload current hours, long time fuse; overcurrent large, time is short fuse . Melt tube fuse installed in the fuse body. Then inserted in the holder or directly used on the circuit. Fuse is set at both ends of a metal cap or completely sealed with a touch of insulated pipe cutter. This fuse inside an insulating tube if filled with quartz sand, it has the effect of limiting fuses when breaking current, can greatly improve the breaking capacity, it is also known as high breaking capacity fuses. If the inner tube is evacuated Wuhan high-voltage fuse, the fuse is called vacuum. If the inner tube is filled with SF6 gas, SF6 is known fuse, which aims to improve the arc extinguishing performance. Because of quartz sand, vacuum and SF6 gas has better insulation properties, so this is not only suitable for low voltage fuses are also suitable for high pressure. Xiangfan high-voltage fuse | Huayi Electric Power (certified) | fuses provided by Xian Huayi power plant.
