The shunt capacitor is composed of a pack, a case, an outlet porcelain busing, etc. The two sides of stainless steel case are welded with hanging brackets for installation, and one hanging bracket is equipped with a grounding bolt. In order to adapt to various voltages, the pack is composed of several small elements connected in parallel and series. The capacitor is equipped with a discharge resistor.
High-voltage shunt capacitors are suitable for 50Hz or 60Hz AC power systems to improve the power factor of the power frequency power system, reduce line losses, improve the quality of the power supply voltage, and increase the active output of the transformer.

The capacitor unit is designed and manufactured with advanced technology at home and abroad.
The components are made of aluminum foil and polypropylene film.
The fully insulated core is housed in a stainless steel shell, which is vacuum treated and impregnated with C101 liquid medium.
The internal fuse also adopts the most advanced 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 core is connected in parallel with discharge resistance.
The use of a new type of rolling bushing, and the box shell adopts automatic argon 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.
