The capacitor unit is designed and manufactured with advanced technology.
The components are made of aluminum foil and polypropylene film.
The fully insulated pack is housed in a stainless steel case, which is vacuum treated and impregnated with liquid medium.
The internal fuse also adopts state of art fuse structure in the world, and the fuses of each component are completely isolated, which fundamentally eliminates the problem of fuse group explosion. It adopts aluminum foil folding and convex structure, and each serial section of the pack is connected in parallel with discharge resistance.
The use of a new type of rolling bushing, and the case adopts automatic TIG arc welding, which effectively solves the problem of capacitor oil leakage.
Through the above measures, the capacitor unit has low loss, small partial discharge and long life.
Before leaving the factory, the products are tested one by one.

3.1 Casing: Cold-pressed, anti-fouling type casing is adopted, and the creepage distance is not less than 31mm/kV.
3.2 Mature internal fuse technology.
3.3 Liquid medium: 100% benzyltoluene (M/DBT) is used. This liquid has excellent low temperature performance and partial discharge performance.
3.4 The main insulation adopts a composite insulation structure, which not only guarantees excellent electrical performance, but also has a certain degree of mechanical strength, which ensures that the insulation of the capacitor complete set of devices is 100% reliable without protection.
