Step 2
Features
01
High safety
Mining cables usually have good fire resistance and are made of fireproof, flame-retardant or fire-resistant materials to ensure that the cables can effectively prevent the spread of fire and ensure the safety of miners when a fire occurs.
02
Anti-mechanical damage
Mining cables are usually designed with strong compression, tension and wear resistance to adapt to the complex working environment in mines, especially in environments such as high pressure, high humidity, dust and chemical corrosion, where cables need to withstand greater mechanical impact.
03
Anti-electromagnetic interference
Mining cables are often equipped with metal shielding layers to effectively prevent electromagnetic interference and ensure the normal operation of the power system and the stable operation of equipment.
04
High and low temperature resistance
Mining cable materials can adapt to severe cold or high temperature environments, and are particularly suitable for use in places with large temperature differences such as mines to ensure the reliability of power supply.
05
Moisture and corrosion resistance
The outer sheath and insulation materials of mining cables usually have good moisture resistance, can work stably for a long time in a humid environment, and have strong corrosion resistance.
06
Explosion-proof performance
In flammable and explosive environments such as coal mines, some mining cables adopt explosion-proof design and comply with relevant national standards. For example, cables for coal mines are usually required to comply with the "Technical Regulations for Safety of Power Cables for Coal Mines".
07
High reliability
Mining cables have a long service life and often need to be used for a long time in extremely harsh environments. Therefore, the structural design and material selection of cables pay great attention to long-term stability and high reliability.
