- Product Introduction
Engineered for reliable reactive power compensation, the Jinneng BKMJ Series is a fully dry, self-healing low-voltage shunt capacitor. Constructed from premium metallized polypropylene film, each internal capacitor unit features a built-in fuse protection structure. The entire assembly is housed in a robust cold-rolled steel enclosure and filled with non-toxic, fire-resistant vermiculite, ensuring superior safety, zero leakage risk, and long-term operational stability in harsh industrial environments.
Products Feature
100% Dry & Eco-Friendly Design: Eliminates the risk of oil leakage and environmental pollution. The enclosure is filled with inorganic, inert, and flame-retardant vermiculite, which safely absorbs any internal arc energy in the event of a failure.
Built-in Fuse Protection: Every capacitor unit is equipped with an internal overpressure fuse. In the rare event of a dielectric breakdown, the faulty unit is instantly and safely isolated without affecting the rest of the system or causing catastrophic failures.
- Advanced Self-Healing Technology: Utilizing high-quality metallized film as the dielectric, the capacitor can automatically heal minor dielectric breakdowns. This ensures continuous operation, stable capacitance, and an extended service life.

FAQ
Q1: What is the difference between a "Dry-Type" capacitor and a traditional "Oil-Filled" capacitor?
A: The BKMJ Dry-Type Capacitor uses a solid, non-toxic filling material (vermiculite) instead of insulating oil. This eliminates the risk of oil leakage, which can damage equipment and create environmental hazards. Dry-type capacitors are safer for indoor installations and require less maintenance.
Q2: Is this capacitor suitable for harmonic-rich environments?
A: While the BKMJ series is designed for fundamental frequency (50Hz) compensation, we recommend pairing it with a detuned reactor (anti-harmonic filter) if your system has significant harmonic distortion (e.g., from VFDs or transformers). Please consult our engineering team for harmonic analysis.
Q3: What certifications does this product have?
A: Our capacitors are manufactured in accordance with IEC 60831-1/2 standards. We can provide test reports and certificates of conformity upon request.
