In the deep, damp mines, mining rubber-sheathed cables act like a resilient blood vessel,
continuously supplying power to underground equipment, becoming a "lifeline" ensuring
operational safety and efficiency. Their unique performance design makes them
irreplaceable in harsh environments.
I. Core Performance Advantages
Perfect Combination of Mechanical Protection and Flexibility
The mine environment is complex and changeable. Mechanical stresses such as rock
friction and equipment dragging constantly threaten cable safety. Mining rubber-
sheathed cables use a high-strength rubber sheath, exhibiting excellent tensile,
compressive, and impact resistance. The internal cores are tightly arranged,
providing excellent flexibility. Whether it's the frequent movement of coal mining
machines or the continuous operation of tunneling machines, the cable can maintain
a stable power supply, avoiding the risk of breakage due to bending or compression.
Dual Protection of Electrical Safety and Flame Retardant Protection
Underground operation safety is paramount, and the electrical stability of cables directly
impacts personnel lives. Mining rubber-sheathed cables feature high-voltage resistant
insulation and low-resistance conductive cores, effectively reducing transmission losses
and ensuring efficient power delivery.Simultaneously, their flame-retardant properties
meet stringent standards, producing low smoke and no toxicity during combustion,
buying valuable time for underground escape and rescue.
Dual Support from Technical Standards and Maintenance Specifications
Mining rubber-sheathed cables must pass rigorous bending and torsion tests, compression
tests, and other mandatory certifications. During installation, they must be kept in a natural
hanging state, with a bending radius no less than six times the cable diameter to avoid
mechanical damage. These standards and specifications provide a solid guarantee for the
long-term reliable operation of the cables.Mining rubber-sheathed cables, this "lifeline" of
underground operations, protect every inch of space in the mine with their superior
performance and stringent standards, safeguarding the safety of miners and the efficient
extraction of minerals.
II. Application Scenarios
Power Supply for Mobile Equipment: Provides power to large equipment such as coal
mining machines, conveyors, and ventilation fans.
Lighting and Control Systems: Provides stable power to critical equipment such as mine
lamps and ventilation systems, reducing wiring complexity.
Safety-Sensitive Areas: Flame-retardant and shielded cables are prioritized for use in
mining faces with the risk of gas or coal dust explosions.
III. Technical Standards and Maintenance
Testing Requirements: Mandatory certifications must be passed, including bending and
torsion tests (≥5000 cycles) and compression tests (≥2500N).
Installation Specifications: Maintain a natural hanging state; the bending radius should not
be less than 6 times the cable diameter to avoid mechanical damage.
Mining rubber-sheathed cables, with their multiple protective designs, have become a key
infrastructure ensuring the continuity and safety of underground operations.
