Power capacitors - Circutor

Power capacitors, LVCVLow voltage three-phase power capacitorsDescriptionFeaturesThe CV dry-type prismatic capacitor rangecovers all power and voltage requirements,from 50 to 60 Hz.The design, manufacturing and testing processesof tubular capacitors guarantee theproduction of top quality and long lasting capacitors.The 4 internal protection levels (self-regulationof the internal fuse, protection cover andvermiculite) make prismatic capacitors thesafest units in the market.ApplicationIts application is based on the compensationin installations with fixed and variable loads(capacitor banks).FeaturesOvercurrentOvervoltageInsulation level1.3 times the rated current permanently10 % 8 over 24 hours15 % up to 15 minutes over 24 hours20 % up to 5 minutes over 24 hours30 % up to 1 minute over 24 hours3 / 15 kVPower tolerance -5...+15 %Discharge resistanceFrequencyLosses:Protections••Dielectric••Total75 V / 3 minutes50 or 60 Hz< 0.2 W / kvar< 0.5 W / kvar••Dielectric regeneration••Internal fuse••Overpressure system••VermiculiteConstruction featuresEnclosure Treated and painted steel, colour RAL 3005Terminals:Torque valueDegree of protectionAmbient conditionsClass C temperature:••Power rating••EarthDaily meanAnnual meanMaximumMinimum••M6 for CV, M10 for CQ, CSB,CSB-6B, CFB, CFB-6B••M6••CV 5 Nm••CQ, CSB, CSB-6B, CFB, CFB-6B: 15 NmIP 42 with terminal cover40 o C30 o C55 o C-40 o CHumidity 80 %Altitude2,000 mAssembly conditionsType of assembly VerticalVentilationNatural or forced, dependingon the cabinet designDistance between capacitors Minimum, 4 cmWeight0.4 kgStandardsCEI 60831-1, CEI 70/7, UNE 20827, UNE 20010, BS 1650, VDE 560R2-15
