Product Description
The NH-YJV (8.7/15kV) is a fire-resistant medium-voltage (MV) power cable designed for mission-critical circuits with extremely high circuit integrity requirements. It features high-purity copper conductors, XLPE insulation (rated temperature 90°C), a mica tape fire-retardant layer, and a PVC/LSZH sheath. It provides stable power at 8.7/15kV (U₀/U, 50Hz) and complies with IEC 60331 / GB/T 19216.21 standards, and can operate energized for over 90 minutes at temperatures of 750–800°C. This product is designed and tested to comply with IEC 60228, IEC 60502-2, CE, RoHS, and ISO standards, meeting the primary needs of engineers and purchasing professionals worldwide: fire safety, electrical reliability, thermal stability, mechanical durability, and regulatory compliance.
Material: Bare copper, Class 2 (IEC 60228), round, stranded, compacted.
Performance: High conductivity (≤0.022 Ω·mm²/m at 20°C), low resistance, optimal current carrying capacity, and excellent short-circuit withstand capability (≤5 seconds at 250°C).
Value: Reduces I²R losses, improves energy efficiency, and ensures thermal stability under peak loads.
Layer: Conductor shielding layer wrapped with high-temperature mica tape.
Performance: Withstands fire for 90 minutes at 750–800°C (compliant with IEC 60331 standard), ensuring electrical continuity of emergency systems.
Value: Meets life safety standards for high-rise buildings, tunnels, subways, and data centers; reduces power outages caused by fire.
Material: Cross-linked polyethylene (XLPE), extruded in a single process, forming a three-layer structure (conductor shielding layer/XLPE/insulation layer).
Performance: Continuous operation at 90°C, short-circuit rated temperature of 250°C, low dielectric loss (tan δ < 0.001)**, high insulation resistance (>500 MΩ·km at 20°C), and excellent partial discharge (PD) resistance.
Value: Long service life (over 10 years), stable performance under high humidity/chemical exposure, and low maintenance costs.
