Medium Voltage, Single-Phase, Unfused Capacitors

Single-Phase_Capacitors.jpg

Cooper Power Systems all-film, unfused capacitors feature extended-foil elements, solderless connections, and laser-cut aluminum foil in a high stacking factor design. Designed, manufactured, and tested to meet or exceed the requirements of applicable IEEE Std C18™-2002 standard (Heavy-Duty and Extreme-Duty capacitors are tested to IEEE Std C18™-2012 standard) these capacitors are a simple, economical, and reliable source of reactive power on outdoor or indoor electric power systems for: improved power factor, system capacitor release, reduced losses, improved power flow capability, voltage support, harmonic filtering and surge suppression. Power capacitors can be installed singly or in factory-assembled switched or unswitched banks in: pole-mounted racks, substation banks, metal enclosures, and mobile capacitor banks.

Catalog Number CEP

Features

All-film, extended-foil, solderless capacitors with a high stacking factor provide:

  • Low dielectric losses (0.05 watt/kvar)
  • Personnel safety through a superior definite tank-rupture characteristic
  • Low capacitance change with respect to temperature
  • Tank rupture curves defined through 10 kA for Standard- and Heavy-Duty and 15 kA for Extreme-Duty
  • Superior electrical performance and reliability
  • Proprietary Edisol™ VI dielectric fluid that provides the best balance between low and high ambient temperature operation
