8.7 / 15 KV Rubber Flexible Cable MYPTJ Eco Friendly For Heavy Equipment
Powering the Depths Sustainably: Shenghua’s MYPTJ Eco-Cables for Extreme Mining Operations
In mining environments where heavy equipment faces crushing loads, high-voltage surges, and toxic fire risks, traditional cables fail catastrophically—causing 40% of unplanned downtime and safety hazards. Shanghai Shenghua Power Group Cable redefines reliability with its MYPTJ 8.7/15KV Eco-Friendly Rubber Cables, engineered to deliver flame-retardant safety, ultra-flexible durability, and EMI-shielded precision for draglines, tunnel borers, and coal cutters operating at 8.7/15KV.
Triple-Shielded Engineering for Heavy-Duty Applications
-
Eco-Safe Fire Resistance:
- Zero-Halogen Rubber Sheath eliminates toxic chlorine/bromine emissions during short circuits, reducing lethal fume release by 90% versus PVC cables—critical for confined underground evacuations
- GB12972-Compliant Flame Retardancy restricts fire spread to <1.5 meters, maintaining circuit integrity for 180+ minutes at 1,000°C (validated in coal mine simulations)
-
Crush-Proof Flexibility:
- Class 5 Copper Conductors (e.g., 276 strands for 35mm²) endure 20,000+ bends at -40°C, resisting cracking in Arctic mines where standard cables fail below -15°C 6× Bending Radius (e.g., 74.3mm OD for 3x185mm²) enables tight routing in excavator joints, reducing snag risks by 50%
-
High-Voltage Reliability:
- Triple-Layer Metallic Shielding (MCPTJ series) neutralizes EMI from 10,000V equipment, preventing arc flashes in methane-rich shafts
- Insulation Resistance up to 1,150 MΩ·km (16mm² cores) minimizes leakage currents, extending lifespan to 10+ years in humid Colombian coal mines
Certified for Global Mining Standards
Shenghua’s MYPTJ series complies with:
- GB12972 & MT818: Flame-retardant and tensile strength testing (3,000V/mm dielectric strength).
- ISO 9001/OHSAS 18001: Safety management for underground deployments.
- RoHS: Halogen-free verification (Cl <50ppm).
