The main fuse from the melt, housing and bearing three parts, which are key components to control the melt fuse characteristics. Material, size and shape determine the melt fusing characteristics. The melt material is divided into two types of low melting point and high melting point. Low melting point materials such as lead and lead alloys, low melting point easily blown, due to its greater resistance Chengdu high-voltage fuse, it made a larger cross-sectional dimensions of the melt, fuse metal vapor produced when more is only applicable to low breaking capacity fuses. Refractory material such as copper, silver high voltage fuse, its high melting point, is not easy to fuse, but because of its low resistivity, can be made smaller than the cross-sectional dimension melt the low melting point, is blown to produce a high pressure metal vapor less Lanzhou fuses for high breaking capacity fuses. The shape of the melt into filaments and two ribbon. Variable cross-section shape change can significantly alter the characteristics of the fuse. There are various fuses fusing characteristic curve, can be applied to the needs of different types of protected objects. Chongqing simple structure open high-voltage fuse fuse, melt completely exposed to the air, from ceramic column for support, no bearing, suitable for low-voltage outdoor use. Have a greater voice breaking current when light in the atmosphere. Jieyang high voltage fuses, Huayi Electric Power (certified), high voltage fuses provided by the Xi'an Huayi power plant.
