4 Core XLPE Power Cable 50mm2 YJV32 SWA Arnoured Copper Power Cable
XLPE Power Cable 4 Core 50mm² YJV32 SWA Arnoured Copper Power Cable
4x50mm² YJV32 series is engineered for primary feeder circuits in environments where high current loads meet extreme mechanical stress. Utilizing heavy-gauge Galvanized Steel Wire Armor (SWA), this cable is the gold standard for direct burial in rocky soil and high-rise power shafts. It provides 360° crush resistance and superior longitudinal strength (14,000 N), ensuring zero-interruption power for critical industrial machinery.

Differentiated Technical Advantages
High-Impact Earth Protection
Designed for "Direct Burial" without additional conduits. The 1.6mm steel wire armor protects the 50mm² cores from heavy equipment vibration and ground shifting.
Balanced Phase Thermal Management
The 4-core 50mm² symmetry ensures uniform heat dissipation, critical for 24/7 industrial feeder operations at a continuous 90°C rating.
Seismic & Subsidence Resilience
The SWA layer provides a "flexible backbone," allowing the cable to adapt to soil subsidence and seismic activity without fracturing the copper conductors.
