Polystyrene Power Shunt Low Voltage Electric Polypropylene Film Capacitor with High Quality Bsmj

Product Description

Product Description

  BSMJ series Low-voltage self-healing parallel capacitors are reactive power compensation devices used in low-voltage power systems of 1kV and below. They achieve rapid self-recovery of insulation performance after dielectric breakdown through metallized thin-film dielectric. Their main functions are to improve power factor, power quality, and grid reliability. They are characterized by excellent self-healing properties, strong overvoltage and overcurrent capabilities, built-in discharge resistors, and explosion-proof design. They can effectively compensate for reactive power and reduce losses.
