Application
Mine trailing cables are designed for various uses, including main feeder cable for continuous miners, pump cable, and power supply cable. Overall semiconductive screen provides protective earth contact for any object breaching the sheath prior to contact with power conductors.
Certification
Mine trailing cable is SAA certified. The cable is specially designed with reinforced outer sheath and metal armor layer, which has extremely high pressure resistance and wear resistance. Whether in the harsh working environment of the mine or when the cable is dragged by mechanical equipment, its outer layer material can effectively resist mechanical damage and extend the service life of the cable. The outer sheath and armor materials are specially treated to make them extremely impact resistant. Even when encountering equipment collision or other external force impact in the mine, the cable can maintain stable electrical performance and avoid the risk of power outage or equipment failure. The cable needs to bend frequently or pass through narrow spaces. The SAA-certified traction cable adopts an optimized design to ensure that the cable can still maintain stable electrical performance at a small bending radius and avoid internal damage caused by excessive bending.

FAQ
Q: What are the common types of mining cables?
1. Mining power cables are mainly used to provide power in dangerous environments such as mines. Their insulation materials are generally flame-retardant materials to prevent the spread of fire. Common types are:
1.1PVC power cable: suitable for power transmission in ordinary coal mines and non-coal mines.
1.2 Rubber sheathed power cable: has stronger wear resistance and corrosion resistance, suitable for use in harsh environments.
2. Mining control cables are used to transmit control signals and information, and are usually used in the automation control system of mine equipment. Its outer layer usually has strong anti-electromagnetic interference ability. Common types are:
2.1 Shielded control cable: multiple strands inside, with strong anti-interference ability, suitable for complex electromagnetic environments.
2.2 Plastic control cable: suitable for places with high requirements for electrical performance, with strong corrosion resistance.
3. Mining signal cables are mainly used for signal transmission in mines, including alarm signals, communication signals, etc. Signal cables usually have high insulation and anti-interference capabilities.
3.1 Telephone cable: dedicated to mine communication system to ensure smooth communication.
3.2 Fire alarm cable: used for fire alarm system, with fireproof function.
4. Mine explosion-proof cable is specially designed for the environment with explosive gas or dust in the mine, which can prevent electrical equipment from causing explosion.
4.1 Explosion-proof power cable: used in flammable and explosive environments such as coal mines, with special explosion-proof structure design.
4.2 Explosion-proof control cable: used for signal transmission of mine automation control system to prevent explosion caused by sparks or arcs.
