TUV Rheinland Certification: Jinneng Electric Power Capacitors Fully Pass IEC 60831-1&2 Tests
Apr 20, 2026| Jinneng Electric Power Technology (Hubei) Co., Ltd. recently announced that its BKMJ 440V / 525V cylindrical dry-type self-healing shunt power capacitors have successfully passed all tests in accordance with IEC 60831-1&2:2014.
The stringent testing was performed by Suzhou Electrical Apparatus Science Research Institute, and the authoritative test report (No. CN25NIQL 003) was issued by TÜV Rheinland. Both routine and type tests achieved 100% compliance, certifying that Jinneng's capacitors meet international top-level quality standards.
Full Test Scope Covered:
- Routine Tests 60831-1: Capacitance measurement, dissipation factor (tanδ) test, voltage withstand tests between terminals and to earth, internal discharge device test, and sealing test.
- Type Tests 60831-2:Thermal stability, high-temperature loss measurement, lightning impulse voltage test, discharge test, ageing test, self-healing test, and destruction test.
Key Product Advantages:
✅ 1,500 Hours of Ultra-Strict Ageing Test Passed in One Run
Completed the full ageing sequence: 1.25× rated voltage for 750h + 1,000 charge-discharge cycles + 1.25× rated voltage for another 750h. Stable operation throughout, with capacitance variation limited to only 0.22%, far better than the standard requirement of ±3%, ensuring long service life.
✅ Ultra-Low Loss & Temperature Rise, Leading in Energy Saving & Reliability
Measured dissipation factor (tanδ) ≤ 0.0012, with extremely low temperature rise during long-term operation. Effectively reduces grid reactive power loss and improves power factor, delivering both high efficiency and strong reliability ideal for PV, industrial and grid applications requiring continuous duty.
✅ Insulation & Impact Resistance Far Exceeding Standards
Indoor capacitors feature 6/15kV insulation level between terminals and enclosure. Power-frequency withstand voltage and lightning impulse voltage values both exceed IEC requirements, delivering stronger overvoltage and lightning protection for stable operation in harsh conditions.
✅ Full Series Fully Qualified, Consistent & Stable Quality
All models in the BKMJ 440V / 525V series have passed complete routine and type tests. Unified control in design, materials and production ensures high consistency in mass production, supporting large-scale global deployment.
About the Product:
