The 7.4KV capacitor from Alpes Technologies delivers a nominal power of 558 kvar at a nominal voltage of 7.4 KV and 50 Hz. Engineered for reliability, this indoor unit operates within a temperature class of -15 to +45 °C and features a robust stainless steel bowl with 3 isolated terminals. It utilizes an "all film" dielectric and a biodegradable impregnator, achieving reduced losses of 0.1 W/kvar. Safety and operational longevity are supported by internal discharge resistors that reduce voltage to 75V within 10 minutes, along with a booster and phase-to-ground isolation of 12kV (28 kV 50 Hz / 75 kV shock). The 7.4KV model operates without internal fuses and handles an allowable overvoltage of +10% (12 / 24h) and a permanent allowable overcurrent of +30%. It fully complies with IEC 60871-1 and 2 standards.
