Shunt Capacitors: 15kV, 25kV & 35kV

Shunt Capacitors: 15kV, 25kV & 35kV

Power Factor Correction Capacitors

Trinetics capacitors are robust and reliable; the standard design is rated for an operating ambient temperature range of -40C to +55C, which is a heavy duty rating for other manufacturers.

Trinetics medium voltage capacitors are available in the following configurations:

  • 1 bushing or 2 bushing
  • 50, 100, 150, 200, 300, or 400 kVAr standard sizes
  • 500kVAr, 600 kVAr, and other sizes available*
  • 95, 110, or 125kV BIL (150kV BIL upon request)

*Note: Contact factory for custom kVAr ratings for power factor correction and harmonic filter bank applications.


  • 409 series stainless steel case finish allows superior heat dissipation and offers excellent protection against corrosion in outdoor environments.
  • Capacitors are sandblasted prior to painting.
  • Epoxy primer and two coats of polyurethane top coat are applied.
  • Paint thickness exceeds 85 microns.
  • Welded terminals are mechanically stronger and provide more consistent mounting than soldered terminals.
  • Heavy duty bolted connections provide superior performance to tab-and-crimp.
  • Solid studs eliminate the inconsistencies associated with solder-filled studs.

Trinetics power factor correction equipment is compliant with IEEE 18 and IEC60871-1. 


  • Capacitor kVAr ratings: 50, 100, 150, 200, 300, and 400 (optional:  500 and 600 kVAr)
  • Bushings:  1 or 2 bushings (2-bushings typical)
  • Bushings (creep): 14.95” (380mm), 23.6” (600mm), 30” (762mm)
  • Temperature category: -40C to +55C
  • Case: 409 series stainless steel
  • Dielectric type: All polypropylene film
