BSMJ0.4-25-3 Power Capacitor Product Introduction (English Version)
The BSMJ0.4-25-3 is a three-phase shunt power capacitor specifically designed for reactive power compensation in 0.4kV low-voltage distribution systems. With a rated capacity of 25kvar and compatible with 50Hz AC power networks, this product effectively improves power factor, optimizes power quality, and reduces line losses in electrical grids.
Featuring modular construction, the capacitor integrates over-voltage disconnection protection that rapidly isolates faulty circuits during abnormal operation. The flame-retardant engineering plastic enclosure provides excellent heat resistance and moisture protection (IP20 rating). Its compact cubic design (typical dimensions 245×85×165mm) allows flexible vertical or horizontal installation in various distribution cabinets.
Advanced metallized polypropylene film technology forms the core of this capacitor. The self-healing dielectric layer, created through vacuum metallization, features nanometer-grade conductive coating that vaporizes instantaneously at defect points to prevent fault propagation. Dry-type internal components eliminate liquid leakage risks associated with traditional capacitors. Optimized cooling channels combined with aluminum alloy heat sinks ensure stable thermal performance during continuous operation.
This product is ideal for power system upgrades in industrial plants, commercial buildings, and renewable energy stations. When paired with reactors, it forms harmonic filtering compensation systems. In applications with inductive loads such as motors, transformers, and frequency converters, it effectively suppresses harmonic interference and extends equipment service life. Recommended operating conditions include ambient temperature range of -25℃ to +55℃, altitude below 2000 meters, and relative humidity ≤85%RH.
The BSMJ0.4-25-3 demonstrates low operational losses, minimal temperature rise, and slow capacitance degradation, delivering over 100,000 hours of service life. Enhanced internal connection structures and terminal designs reduce contact resistance, maintaining three-phase imbalance within ±1.5%. Rigorous 72-hour aging tests and partial discharge inspections ensure batch-to-batch consistency before shipment.
