Pole-mounted capacitor banks QPole

Cost-effective way to apply capacitors to a distribution feeder system

Hitachi Energy's pole-mounted capacitor banks provide an economical way to apply capacitors to a distribution feeder system to provide voltage support, lower system losses, release system capacity and eliminate power factor penalties. They are factory pre-wired and assembled, ready for installation.


  • In-line aluminum or galvanized steel rack
  • Oil or vacuum switches 
  • Junction box
  • Switching controller
  • Wildlife guards
  • Insulated conductor
  • Control power transformer
  • Distribution class arresters
  • Fused cutout
  • Current limiting reactors


The QPole can be used for voltage stability applications, reactive compensation or volt-var management.

QPole is available in two configurations: fixed or switched. Fixed banks are preferred for networks with less varying load profiles, while switched banks are more suited to networks with highly varying load profiles.
