Application explanation of mining rubber sheathed cables in power transmission in mines
Date: 2025-11-24Read: 0
The mining production environment is complex, with narrow underground spaces, high humidity, and large dust, as well as safety hazards such as gas and roof falling. This places high demands on the reliability, durability, and safety of power transmission cables.Mining rubber sheathed cableWith its material properties and structural design, it has become the core carrier of mining power transmission, providing stable power support for key links such as mining equipment, ventilation systems, drainage devices, and lighting facilities. 
1、 Protective armor adapted to harsh environments
Mining rubber sheathed cableIt is characterized by a special rubber sheath for its outer layer, which has natural wear resistance, tear resistance and aging resistance. In underground tunnels, cables often need to be moved and dragged with equipment, or subjected to rock collisions and ore compression. Ordinary plastic sheaths are prone to cracking and damage, while the elasticity and toughness of rubber sheaths can effectively buffer mechanical stress and avoid short circuits caused by external force damage to internal conductors. At the same time, the rubber sheath also has moisture-proof and anti-corrosion properties, which can resist the infiltration of moisture in the high humidity environment underground, as well as the erosion of mineral dust and chemical gases, prevent the insulation layer from being affected by moisture, leakage or aging, and extend the service life of the cable.
2、 Flexible transmission power bridge
Mining equipment often requires frequent movement or adjustment of position, which places high demands on the flexibility and bendability of cables. Conductors are usually made by twisting multiple strands of thin copper wire, which is softer than a single thick wire and can easily adapt to the twisting and winding actions of equipment; The soft rubber material of the insulation layer and sheath further enhances the overall bending performance, ensuring that the cable can maintain its insulation performance after repeated bending, avoiding power outages caused by conductor breakage or insulation layer damage. In addition, the lightweight design of rubber sheathed cables also reduces the load on equipment movement and improves operational flexibility.
3、 Safe and reliable power guarantee
The underground environment contains flammable and explosive substances such as gas and coal dust, and the safety of power transmission is crucial. The insulation layer and sheath material are both made of flame-retardant formula, which is not easy to burn when encountering open flames or high temperatures. Even if locally ignited, it will extinguish on its own, avoiding the spread of fire along the cable and causing greater accidents. Some cables are also designed with grounding core wires to promptly introduce static electricity or leakage current generated during equipment operation into the ground, reducing the risk of electric shock; In special scenarios, shielded rubber sheathed cables will also be used to isolate electromagnetic interference through a metal shielding layer, further ensuring the stability of power transmission and personnel safety.
Mining rubber sheathed cables are the "lifeline" of mining power systems, and their characteristics such as wear resistance, bending resistance, and flame retardancy are suitable for complex underground working conditions. From the power supply of mining equipment to the continuous operation of ventilation and drainage systems, it supports every aspect of mining production with reliable performance and is an important basic equipment to ensure safe and efficient mining operations.
