1、 Communication signal cable

MHYV: Polyethylene insulated polyvinyl chloride sheathed communication cable, used for ordinary signal transmission (fixed laying).

MHYVP: Polyethylene insulated copper wire braided shielded polyvinyl chloride sheathed cable, suitable for strong electric field interference environments.

MHY32: Polyethylene insulated steel wire armored polyvinyl chloride sheathed cable, used for high mechanical strength scenarios such as vertical shafts and inclined shafts.

MHYSV is a communication transmission medium designed specifically for mining environments, mainly used for safe production and efficient operation of mines.

MHYSV cables have the following main characteristics:

Environmental adaptability: MHYSV cables use special insulation and sheath materials, which can effectively resist moisture, corrosion, and mechanical impact in mines, ensuring that signals remain clear and stable in complex and changing underground environments

Signal transmission stability: Its finely twisted conductor structure optimizes signal transmission efficiency, reduces signal attenuation and interference, and ensures that every instruction and data can be accurately delivered to the destination without error

Flame retardant and explosion-proof performance: MHYSV cables have excellent flame retardant and explosion-proof performance. Even in the event of sudden fires or explosions in mines, they can effectively isolate the source of fire, prevent the situation from escalating, and win valuable time for the safe evacuation and rescue operations of mine personnel

Multiple specifications: MHYSV cables have multiple specifications, such as MHYSV 10x2x0.8, 20x2x0.8, and MHYSV 100x2x1/0.8, which represent the number of copper wires inside the cable, the twisting method of wire pairs, and the shielding structure

For example, the MHYSV 100x2x1/0.8 cable consists of 100 pairs of precision twisted copper wires inside, each pair of copper wires is protected by a double insulation layer and further shielded from external electromagnetic interference through a high-density metal shielding layer to ensure signal purity

These characteristics make MHYSV cables play an important role in modern mine communication systems, providing strong support for intelligent management, remote monitoring, and emergency command of mines.

Strong interference environment: Priority should be given to cables with shielding layers (such as MHYVP, MKVVRP) or armor (such as MHY32).

Mobile devices: require flexible cables (such as MYP, MYQ) with a bending radius of ≥ 6 times the outer diameter.

Safety certification: All mining cables must be certified with the MA mark.
