BAMH集合式电容器中英文简介

Assembled Capacitor

1.General Description

Assembled shunt capacitors are mainly used in 6kV, 10kV, 35kV, 66kV frequency power syst em for reactive power compensation, which could improves the power factor of a power grid, redu ce power loss and stabilize voltage. Thus the eciency of power generation, supply and equipment a re improved.

The advantages of shunt capacitor are: anti-explosion, antire, safe & reliable, small footprint, easy installation and maintenance, high commissioning rate and low operation cost.It is especially suitable for updating urban power grid and compensation for large scale transformer substation.
