BZMJ Series Self-healing Low Voltage Parallel Capacitor
The BZMJ series self-healing low voltage parallel capacitor is designed for power factor improvement and voltage quality enhancement in AC power systems with a rated voltage of 1000V and below. It features a metalized polypropylene film dielectric and rapeseed oil impregnation. The capacitors are suitable for use in environments with ambient air temperatures from -25 to +50 (customizable for -40 to +50), relative humidity up to 90% at 20, and an altitude of up to 2000m. They are designed for environments free of harmful gases, conductive or explosive dust, and severe mechanical vibration. Key advantages include a smaller volume, higher reliability due to imported production equipment and materials, adaptability to higher ambient temperatures and voltage fluctuations, improved sealing, convenient and reliable wiring, and a durable, corrosion-resistant metal casing.
