Main technical data

Voltage: 1kV~25kV

Capacitor capacitance: 100kvar~800kvar

Variation of capacitor: 0~±5%

Loss angle(tanδ) at rated voltage ≤0.002

Long_term operation at 1.05 times of rated voltage can be allowed and it also can operate at 1.15 times of voltage for less than 30min. every 24hrs.

It can operate at 1.30In steady over-current caused by higher harmonic and steady over-voltage. Steady over_current can be allowed to reach 1.5In for capacitor with extremely plus variation.

It is complying with GB/T11024_2001 hunt capacitor for AC power system of nominal voltage 1KV and above and IEC 60871-1:1997 HV shunt capacitor technical condition.

Structure characteristics

It uses double_piece coarsening polypropylene film to keep good impregnation. Components do edge fold convex structure to reduce partial discharge and improve polarity board insulation’s electric field distribution.

Crimping high-strength porcelain bushing with high hermetically sealed performance is applied to capacitor bushing. The welding between bushing and case is with argon arc welding with higher mechanical strength and hermetically sealed characteristics.

Case is made of stainless steel plate, treated through shot blasting and then painting by robots. Surfaces are beautiful with strong anti-corrosion feature.

High reliable inner fuse , good ampere-time characteristics and reliable action.
