Model and meaning
Functions and Features
Full insulation, full sealing, less maintenance, reliable to ensure personal safety;
Compact structure, volume is only 1/3-1/5 of the same capacity eurovariable, low height;
Can use separate box structure, avoid oil pollution in transformer tank;

Fuse technical parameters (recommended table for selection and configuration of oil-immersed fuse of our company)
American box variable high pressure side by the backup protection fuse and plug fuse series to provide full range of protection, simple principle, economic and reliable; The backup protection fuse is oil-immersed high-voltage current limiting fuse, which has a large breaking capacity and can only operate when the transformer is in internal failure. The plug-in fuse is equipped with double-sensitive fuse, which can provide dual protection of current and temperature. After the double-sensitive fuse is broken, the fuse can be easily replaced on site.
