High voltage parallel (series) capacitor bank

The SDrHVM shunt capacitor bank is installed in the power grid, which is mainly used to compensate the reactive power of the system, improve the power factor, and also help stabilize the voltage and reduce the network loss. Improving the power factor also means increasing the power transmission capacity and enhancing the power flow control. SDrHVM frame type capacitor bank, configurable inner fuse, outer fuse, no fuse capacitor unit. Its main advantages are compact design, small footprint and easy maintenance.

Product Description

Product overview

The SDrHVM shunt capacitor bank is installed in the power grid, which is mainly used to compensate the reactive power of the system, improve the power factor, and also help stabilize the voltage and reduce the network loss. Improving the power factor also means increasing the power transmission capacity and enhancing the power flow control.

SDrHVM frame type capacitor bank, configurable inner fuse, outer fuse, no fuse capacitor unit. Its main advantages are compact design, small footprint and easy maintenance.

 

Application areas

It is mainly used on the 3 ~ 35kV bus of the total step-down substation of large and medium-sized enterprises in petrochemical, metallurgy, mining, building materials, water supply and drainage, power grid and other industries.
