Drop Fuse Cutouts
HGW Series Disconnectors
If cooperated with load break tool, it can be used as simple load break switch to break small loading current.
HGW series new designed disconnectors adopted double support insulators, simple, solid, dual-copper contact plates of silver coating, their terminals made of forging brass with coating, composed of two insulators, steel base, contacting copper plate, manual tripping device and etc, all parts made by use of precise molds and machine, strict assembly and adjustment. As the disconnectors are outdoor operating, all parts have been treated fully with corrosion proof, acid and alkali resistant, anti-aging methods. The insulators can be porcelain type, polymer type or epoxy resin type.
The disconnectors are used in the 3~24KV distribution lines, to switch off/on the lines without loading current, to perform the function of electric safe isolation, it is one of main electric switching devices.
The disconnectors comply with GB1985 and IEC 62271-102 standards.
