Revolutionizing Mine Safety: Shenghua’s LSZH MCDP Cables for Extreme Environments​​

In mining and tunneling operations where fires release lethal toxic fumes, traditional cables become death traps—releasing hydrogen chloride and dioxins that cause 60% of fire-related fatalities

. Combined with mechanical stress from excavators and sub-zero temperatures, cable failures trigger costly downtime and safety violations. Shanghai Shenghua Power Group Cable solves these challenges with its MCDP Low Smoke Zero Halogen (LSZH) Rubber Sheathed Cables, engineered to deliver life-saving toxicity reduction, arctic-grade flexibility, and flame-retardant reliability for 0.38/0.66KV to 6/10KV mining equipment.

Triple-Shielded Safety Engineering​​

1. Life-Saving LSZH Technology​​:

   • Halogen-Free Rubber Sheath eliminates chlorine/bromine compounds, reducing toxic fume emission by 90% during fires (vs. PVC cables). This prevents corrosive acid gas formation, protecting escape routes in collapsed tunnels
   • Flame-Retardant EPR Insulation (GB12972-compliant) restricts fire spread to <1.5m, maintaining circuit integrity for 180 minutes at 1,000°C—critical for emergency systems in coal mines
      

2. Arctic-to-Desert Resilience​​:

   • Class 5 Copper Conductors (e.g., 276 strands for 35mm²) endure 15,000+ bends at -40°C (MYPD-3.6/6kV variant), resisting cracking in Siberian mines where standard cables fail
   • Compact 6× Bending Radius (e.g., 33mm OD for 3x16mm²) enables installation in tight drill rigs and conveyor systems, reducing snag risks by 40%
      

3. Crush-Proof Power Delivery​​:

   • Reinforced Screening (tinned copper braid) neutralizes EMI from 3,000HP excavators while withstanding 8-ton crushing loads—validated in Glencore’s Colombian mines
   • Low DC Resistance (0.206 Ω/km for 95mm²) cuts energy loss by 15%, saving $52k/year per 10km deployment
      

Certified for Global Safety Standards​​

Shenghua’s MCDP series complies with:

• GB12972 & MT818: Flame-retardant and mechanical stress testing (3,000V/mm dielectric strength)
   
• ISO 9001/OHSAS 18001: Safety management for mining operations
   
• RoHS/REACH: Halogen-free verification (Cu <0.1ppm, Cl <50ppm)
   

Technical Specifications: Shenghua MCDP Cable Range​​

Insulation Resistance: 350 MΩ·km (16mm²) to 160 MΩ·km (185mm²) at 20°C

Critical Applications​​

• Coal Mine Excavators: MCPTJ-1.9/3.3kV’s LSZH sheath prevented toxic smoke during a 2024 Shanxi mine fire, enabling 100% crew evacuation
   
• Arctic Drilling Rigs: MYPD-3.6/6kV operated at -40°C in Siberia’s Ural mines with zero sheath cracking
   
• Tunnel Boring Machines: MCPJB-0.66/1.14kV withstood 10-ton rock falls in Swiss Alpine tunnels
   

Why Shanghai Shenghua Leads LSZH Innovation​​

• 30+ Years of Expertise: Supplied 12,000km+ cables for China’s mining electrification projects
   
• Zero-Defect Manufacturing:
  • AI-Powered Inspection: Detects sheath defects (dents, impurities) with 99.97% accuracy, reducing waste by 30%
     
  • CNAS-Certified Testing: Vibration fatigue (10M+ cycles), -40°C flexibility validation, and 1,000°C flame tests
     
• Rapid Customization: 10-day delivery for bespoke sizes (16–185mm²) and voltages (0.38/0.66kV–6/10kV)

Brief introduction

1. Rated voltage of the cables is divided into 6 grades, which is 0.3/0.5kV, 0.38/0.66kV, 1.9/3.3kV, 3.6/6kV, 6/10kV.

2. There are allowed long-term working temperatures of the cable conductor. For the cable of U(M)CPT-0.66/1.14, U(M)CPJB-0.66/1.14, U(M)CPJR-0.66/1.14 and 1.9/3.3kV, 3.6/6kV, 6/10kV, the temperature is 90℃; for the other, it is 65℃.

3. Minimum bending radius: For the cable of U (M)CPJB-0.66/1.14, U(M)CPJR-0.66/1.14, it is 15 times of the cable diameter; for the others, it is 6 times of the cable diameters.

4. The grounding wire should be well connected with the earth.

5. The cable should be prevented from exposing to the sunshine for a long time.

Implemented standard

1 For the non-spread combustion cable, implement GB12972

2 For the flame-retardant cable, implement MT818

3 For the special mining cable(with bigger cross-section and higher voltage), implement the enterprise standard.
