Product Introduction
This four-core mine dedicated power cable (MYJV 3×70+1×35) is rated at 0.6/1kV, designed for fixed low-voltage power transmission in non-high-gas underground coal mine roadways and mine ground plants. It adopts solid oxygen-free copper conductors, cross-linked polyethylene (XLPE) mine flame-retardant insulation, elastic filling wrapping and anti-coal-dust PVC outer sheath. Compared with rubber flexible MY cables, this rigid XLPE mine cable features higher temperature resistance, larger ampacity and longer service life, specially for static power supply circuits of underground fans, water pumps and belt conveyors without frequent dragging movement. It fully complies with national coal mine safety industry standards.
product key technologies
1.Solid high-purity oxygen-free copper conductors: 3×70mm² main phase cores + 1×35mm² protective earth core
2.Mine flame-retardant XLPE cross-linked insulation for each single core
3.Elastic filling materials + binding isolation wrapping tape
4.Black anti-abrasion, dust-proof PVC outer protective sheath
- Solid Copper Conductors：High-density solid oxygen-free copper delivers ultra-low DC resistance and large load-carrying capacity to match heavy-power mining equipment. The matched 3-phase+1-earth integrated layout realizes power transmission and equipment grounding protection in one cable, eliminating scattered wiring inside mine roadways. Rigid conductor structure adapts to long-distance fixed laying in cable trays and underground pipelines.
- Mine-Specific XLPE Flame-Retardant Insulation Layer：Cross-linked polyethylene can continuously operate at 90℃, far superior to PVC insulation in heat resistance and overload tolerance. Special coal mine flame-retardant formula restricts flame spread when short-circuit ignition occurs underground, reducing mine fire risks, while maintaining stable insulation performance under damp mine air.
- Fillers & Wrapping Tape：Elastic fillers round out the cable body to buffer minor extrusion from underground rock and coal debris; wrapping tape locks internal core layout to prevent dislocation deformation during laying.
- PVC Mine Outer Sheath：Thickened modified PVC outer layer resists coal dust accumulation, underground mine water damp corrosion and light mechanical abrasion, isolating internal insulation cores from harsh underground roadway environments.
Key Advantages
- High-Temperature XLPE Insulation: Long-term allowable working temperature up to 90℃, higher ampacity and stronger overload resistance than PVC insulated mine cables.
- Coal Mine Flame-Retardant Safety Formula: Meets mine fire protection standards to inhibit flame propagation, critical for underground safety operation.
- Integrated 3P+E Four-Core Layout: Combines three live phases and protective earth wire into a single cable, simplifying underground roadway wiring and cutting construction costs.
- Harsh Underground Environment Adaptability: Resists coal dust, mine water moisture and light rock abrasion, suitable for long-term fixed laying in damp underground tunnels.
- Long Service Life Anti-Aging Performance: XLPE insulation effectively slows thermal aging, with stable service life over 30 years under standard mine laying conditions.
- Mine Standard Compliance: Passes coal mine safety performance tests, eligible for bidding of underground non-explosion-proof fixed power supply projects.

FAQ
Q1: What does MYJV stand for?
A: M = Mine dedicated cable; YJ = XLPE cross-linked insulation; V = PVC outer sheath.
Q2: What is the difference between rigid MYJV and flexible MY mine cables?
A: MY uses multi-strand soft copper + rubber insulation, for frequently dragged mobile mining equipment; MYJV uses solid hard copper + XLPE insulation, only for fixed static laying without repeated bending and dragging.
Q3: Can MYJV be used in high-gas explosive-risk coal mine working faces?
A: Not recommended; MYP shielded mine cables are required for high-gas underground areas with explosion hazards. MYJV is only applicable to low-gas fixed roadway circuits.
Q4: What is the maximum short-circuit withstand temperature of XLPE insulation?
A: It can withstand instantaneous short-circuit high temperature up to 250℃ within 5 seconds without insulation breakdown.
Q5: Can we supply armored MYJV22 for direct underground burial in mine soil?
A: Yes, MYJV22 with double steel tape armor is available for underground direct-buried mine roadway laying with mechanical impact risks.
Q6: What is the rated voltage applicable to this mine cable?
A: 0.6/1kV, exclusively for low-voltage three-phase power distribution circuits of mining equipment, not for medium/high-voltage power transmission.
