| Rated voltage | 36kV |
| Rated capacity | 2500kVA |
| Series | Qpole Series |
Qpole pole mount capacitor system is an economical solution for shunt reactive compensation on overhead distribution networks. The Qpole is suitable for use in networks up to 36 kV.
● Power factor correction close to customer loads
● Voltage stability
● Increased network capacity
● Cost savings through lower losses
The Qpole is available as a fixed or switched system depending on the network profile. Fixed systems are preferred in networks with constant loading, whilst switched systems are more suited toward networks with variable loading.
The fixed and switched systems utilize single phase capacitors arranged in grounded Y, un-grounded Y or delta configurations. Three phase capac-itors are also available.
The switched system utilizes the complete range of components including capacitors, vac-uum switches and controller. Optional equipment in-cluding current sensors, surge arrestors and fuse cut-outs are also available.
The Qpole is factory assembled in a galvanised steel or aluminium frame which is suitable for pole mounting. All high voltage wiring and outdoor bushing terminals are provided with protective bird guards for increased safety and reliability.
The Qpole is unique as it offers customers a complete ‘one stop shop’ solution which has all major components manufactured. Each compo- nent is manufactured to a relevant international standard.
