Wear Resistant Rubber Sheath Tinned Copper Conductor Waterproof
Underground Mining Power Cable Flexible Electric Wire
High Voltage 6/10KV Tinned Copper Core Metal Shield Monitoring-type
Mining Cable
MYPTJ cable is composed of twisted tinned copper cores, rubber
insulation, rubber sheathing, and metal shielding. This mobile
metal shielded monitoring type rubber-coated flexible cable is
designed for underground coal mines, primarily used for power
transmission in mobile equipment underground.Capable of long-term
stable operation in the humid, dusty, and corrosive gas
environments of coal mine shafts, with a typical operating
temperature range of -30°C to 65°C.
Product Features
- Rated voltage U0/U: 6/10Kv,8.7/10KV
- Conductor:Made from high-quality oxygen-free copper with high
electrical conductivity, it significantly reduces electrical energy
loss.
- Insulation:Insulating compounds based on high-quality ethylene
propylene rubber can withstand higher voltages, enhancing the
protective performance of cables in harsh environments
- Shield:The internal metal shielding layer effectively isolates
external interference, enhancing signal stability
- Outer Sheath:Constructed from rubber material, it offers excellent
wear resistance and corrosion resistance, effectively withstanding
various chemical corrosions and abrasions encountered in mining
environments.
- Operating temperature range: -35°C to 65°C
- Minimum bending radius exceeds 6 times cable diameter
- Maximum conductor temperature: 65°C
- Tinned copper conductor prevents oxidation and improves
conductivity
- Features: Flexible, waterproof, tensile resistant, explosion-proof,
wear-resistant, oil-resistant, and corrosion-resistant
- Metal shielding layer protects against electromagnetic interference
and provides grounding protection

Applications
This cable is primarily used for power transmission between mobile
substations or mobile transformers in underground coal mines and
equipment at the working face. It connects mobile transformers,
roadheaders, shearer loaders and other large equipment. Suitable
for underground coal mines with flammable and explosive
environments such as gas and coal dust.

Product Features
This cable utilizes tinned copper conductors. The tin coating acts
as a protective layer, isolating the copper from contact with air,
moisture, and corrosive media. This effectively prevents oxidation
and corrosion of the copper, maintaining low resistance at
conductor connection points. It ensures stable current
transmission, avoids increased energy consumption or equipment
failures caused by excessive contact resistance, and delivers more
stable electrical performance.
