MKVVR Mine Cable MKVVR 7 * 1.5 Soft Core Control Cable for Coal Mines

🔢 Model meaning disassembly

• MSpecialized for coal mines (Marine corresponds to mining mines)

• KControl cable

• VPolyvinyl chloride (PVC) insulation

• VPolyvinyl chloride (PVC) sheath

• RFlexible structure (corresponding to GB/T 3956 Class 5/6 soft conductor)

• Specific specifications of parameter itemsrated voltage450/750V (underground low voltage control standard)Operating TemperatureThe conductor can withstand 70 ℃ in the long term and 90 ℃ in the short termLaying temperature≥ -20 ℃ (cold resistant and suitable for underground low temperature)conductor specification0.5-6 mm ² (Control circuit mainstream 1.0-2.5 mm ²)Core count range2-61 cores (commonly used 4/6/8/10/12/16 cores)bend radiusNo armor ≥ 6 x outer diameter (soft core suitable for narrow spaces)flame retardant standardOxygen index ≥ 32%, self extinguishing upon ignition, MT 386 single combustion meets the standardanti-staticSurface resistivity ≤ 1 × 10 ΩΩ (anti gas electrostatic spark)

• conductorMulti strand oxygen free copper/tin plated copper wire twisted (Class 5 soft core), vibration resistant, easy to bend, suitable for equipment movement and dragging.

• insulationFlame retardant PVC, insulation resistance ≥ 60 M Ω· km (20 ℃), oil and moisture resistance.

• cablingTwist the core wire, distinguish by color code (such as red/blue/black/yellow), and wrap it with flame-retardant tape after cable formation.

• sheathFlame retardant and anti-static PVC, wear-resistant and oil resistant, suitable for underground gravel friction and humid environments.

• Optional armor：

• Type 22Steel belt armor, for direct burial/cable trench, resistant to mechanical compression;

• Type 32Thin round steel wire armor for high tensile/high impact scenarios (such as vertical shafts).

• ✅ Core Features

• Mobile adaptationSoft conductor design, long bending life, compatible with control wiring of mobile equipment such as coal mining machines, tunneling machines, and conveyors.

• safety complianceMandatory MA certification, compliant with MT818 mining standards, low smoke and no dripping, self extinguishing upon ignition, eliminating the risk of underground fire spread.

• environmental toleranceAnti static, oil resistant, moisture resistant, low temperature resistant, suitable for harsh working conditions such as high gas, high dust, and strong corrosion underground.

• Easy constructionSoft and easy to wear tube, multi-core integration, reducing wiring workload and minimizing on-site losses.
