Why Choose JNCN Power for SC(B)10-35kV Series?
- Precision Engineering for High-Voltage Reliability At the 35kV level, insulation integrity is critical. Our SC(B) series utilizes advanced thin-insulation technology and a specialized filling process that ensures consistent dielectric strength, making it the most reliable choice for demanding high-voltage grids.
- World-Class German Casting Technology We utilize a new generation of German HEDRICH vacuum casting equipment. This system’s vacuum film degassing and automated metering pumps ensure an ultra-precise epoxy mixture, resulting in a void-free, solid-cast winding that is virtually impervious to cracking.
- Industry-Leading Low Partial Discharge Through our rigorous manufacturing control, we maintain partial discharge levels at ≤ 10pC (and even lower for specific models). This significantly exceeds international standards, drastically reducing the risk of insulation breakdown and extending the transformer’s service life.
- Optimized "Airway Bar" Thermal Management Our proprietary axial airway technology creates dedicated cooling channels within the winding’s heat center. This design achieves the best-in-class heat dissipation effect, allowing the unit to handle high loads safely while enhancing overall mechanical strength.
- Extreme Environmental Resilience The epoxy resin encapsulation provides a total seal against moisture, salt spray, and dust. This "Immediate Power-up" design means the transformer can be energized directly after long periods of inactivity or storage in high-humidity coastal and industrial zones.
- Eco-Friendly and Fire-Safe JNCN Power is committed to sustainability. Our cast resin transformers are flame-retardant, self-extinguishing, and non-toxic. In the event of an external fire, they produce almost no smoke, ensuring the safety of personnel in high-rise buildings, hospitals, and underground facilities.
- Modernized 2026 Production Standards Operating from our 2026-standard modernized facility, every 35kV unit undergoes a comprehensive suite of Factory Acceptance Tests (FAT) in our specialized labs to guarantee that your infrastructure receives nothing but peak performance.
