AC single-phase wet-type capacitors
Single-phase capacitors for reactive power compensation and filtering applications ABB AC wet-type capacitors are available in sizes up to 1,200 kvar per unit (at 50 Hz), and are characterized by negligible losses and high reliability. They consist of thin dielectric polypropylene film wound together with electrodes of aluminum foils. Fusing technologies available for these capacitors include internally fused (CHDB), externally fused (CHDE) and fuseless (CHDF) executions. A bio-degradable hydrocarbon compound with excellent electrical properties is used as the impregnation fluid. The container is made of surface-treated high-quality steel - the bushings and terminals are of highest quality and reliability. Applications: Shunt reactive power compensation banks Harmonic filters Series capacitor solutions SVC applications HVDC applications CHDB internally fused - CHDE externally fused - CHDF fuseless Power (50 Hz) 100 - 1,200 kvar 100 - 500 kvar 300 - 1,200 kvar Power (60 Hz) 100 - 1,400 kvar 100 - 600 kvar 300 - 1,400 kvar Voltage 1 - 15 kV 1 - 20 kV 1 - 20 kV Max current 180 A 60 A 180 A |

Three-phase capacitors CHDTP
Three-phase capacitors for reactive power factor requirements in medium-voltage networks The three-phase capacitor CHDTP is a cost-effective solution for reactive power requirements in medium-voltage networks. The capacitors consist of a thin dielectric polypropylene film wound together with electrodes of aluminum foil. Discharge resistors are built-in. A bio-degradable hydrocarbon compound with excellent electrical properties is used as the impregnation fluid. The container is made of surface-treated high-quality steel and the bushings and terminals are of the highest quality and reliability. Applications Open-rack, metal enclosed or pole mounted capacitor banks Power factor correction for motors and load centers Suitable for heavy-duty operation in all climatic conditions Power: Up to 500 kvar Voltage range: 1-20 kV Frequency: 50-60 Hz Current: Maximum 110 A Dielectric: Polypropylene film Impregnant: Non-PCB Discharge resistors: Built-in Losses: ≤ 0.2 W/kvar including resistors Operating temperature: -10/+50°C Location: Indoor or outdoor Altitude: ≤ 1,000 m above sea level |

Medium Voltage Capacitors Units
Medium Voltage Capacitors Three-Phases Units have all-film dielectric and are impregnated with dielectric liquid which is now PCB-free. In addition each capacitor is provided with an internal discharge resistor. All capacitors have low losses and are constructed to be light in weight. The medium voltage power capacitors comply with most national and international capacitor standards. The 3-phases capacitors HVCB 25 kVAR to 300 kVAR externally fused and QYLP 50 to 400 kVAR internally fused designs are available. High voltage single phase units complete with 1 or 2 bushings are also available. |
