FAQs

 

When should I use the BKMJ Dry Type Low-voltage Shunt Capacitor?

This capacitor is best suited for low-voltage AC networks (≤1000V) requiring reactive power compensation to improve power factor and reduce line losses. It’s particularly effective in industrial workshops, substations, and high fire-safety environments due to its oil-free dry design.

 

What makes the BKMJ capacitor safer than traditional oil-filled types?

It uses a dry flame-retardant filling and includes self-healing polypropylene film, over-pressure disconnection, and self-discharge circuits. This eliminates the risk of oil leakage, explosion, or fire, ensuring eco-friendly and maintenance-free operation.

 

Can this capacitor operate in environments with harmonics?

Yes, the BKMJ series can tolerate moderate harmonics. For THDu >5%, CHINT recommends using series reactors (CKSG) with 7% or 14% reactance to suppress harmonics and extend capacitor lifespan.

 

How should I install the BKMJ capacitor for best performance?

Install vertically or horizontally using the plastic mounting feet and 7×10 mm holes. Maintain at least 30 mm spacing between units for ventilation, and 80 mm at altitudes above 2000 m. Ensure good ventilation and tight conductor connections.

 

What precautions should be taken in high-altitude or high-temperature regions?

When used above 2000 m or in ambient temperatures exceeding +50°C, select a higher voltage-rated model to compensate for derating and avoid overheating. Proper spacing and airflow must be ensured for reliable operation.
