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​​

1. ​​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)
     
     

2. ​​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%

3. ​​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).

​​Technical Specifications: Shenghua MYPTJ Cable Range​​

Insulation: Eco-Rubber | Shielding: Tinned Copper Braid | Min. Bending Radius: 6× diameter

​​Critical Mining Applications​​

• ​​Dragline Excavators​​: MYPTJ-8.7/10kV’s 185mm² cores power Siberian coal mines, withstanding -40°C winds and 8-ton mechanical stress.
• ​​Tunnel Boring Machines​​: MCPTJ-1.9/3.3kV survives rock impacts in Swiss Alps projects, with Kevlar-reinforced jacketing.
• ​​Coal Cutters​​: MZ-0.3/0.5kV enables agile drilling in Chilean copper seams, leveraging 15,000+ bend cycles.

​​Why Shanghai Shenghua Leads Heavy-Duty Cable Innovation​​

• ​​Top 10 Chinese Manufacturer​​: Supplied 1,200km+ cables for Glencore’s Kazakh mines, reducing downtime by ​​65%​​
  
  
• ​​Zero-Compromise Production​​:
  • ​​AI-Powered Defect Detection​​: 99.97% accuracy in identifying sheath impurities, cutting waste by 30%.
  • ​​CNAS-Certified Testing​​: Vibration fatigue (10M+ cycles), -40°C flexibility validation, and 1,000°C flame tests.
• ​​Rapid Customization​​: 15-day delivery for bespoke voltages (0.38/0.66kV–8.7/15kV) and shielding configurations
