Safety Features: Integrated discharge resistors, independent over-voltage protection
Design: Dry-type, leak-proof construction with low-loss materials

3.Key Features & Advantages

1. Built for Extreme Conditions

The BKMJ0.4KV capacitor handles ambient temperatures up to 60°C and voltage fluctuations of ±10%, making it ideal for steel mills and foundries. Its explosion-proof design prioritizes safety in high-risk environments.

2. Energy Efficiency You Can Trust

With a loss factor below 0.2W/kVar, this capacitor cuts energy costs by minimizing reactive power waste. Its modular design allows seamless integration into existing systems, reducing downtime during upgrades.

3. Smart Self-Healing Technology

Micro-damage from voltage surges? The self-healing dielectric layer automatically repairs minor faults, extending service life to over 100,000 hours—even in 24/7 operations.

4. Global Compliance, Local Reliability

Certified to IEC 60831, UL, CE, and CCC standards, our capacitors meet regional requirements from North America to Asia-Pacific. Optional GOST and RoHS certifications ensure adaptability to niche markets.

4.Real-World Applications

Be used in a wide range of industries.

Industrial Plants

Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.

Substation

Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.

Commercial Buildings
