Mining flame-retardant and explosion-proof network cable MHYV4 * 2 * 0.5, mining network cable, coal mine monitoring network cable, mining shielded network cable Product structure:

Conductor: Single solid bare copper conductor (0.5mm)

Insulation: Solid polyethylene, colors: blue * white/blue, orange * white/orange, green * white/green, brown * white/brown

Twisted pair: Two insulated core wires are twisted in pairs, with each pair using a different twist pitch to ensure good near end crosstalk (NEXT) characteristics

Cabling: 4 twisted pairs to ensure good near end crosstalk (NEXT) characteristics

Shielding: Aluminum foil and copper wire weaving, weaving density ≥ 60%

Outer sheath: flame retardant blue polyvinyl chloride PVC

The installation of flame-retardant network cables for coal mines must be strictly sealed according to the construction process. The intermediate joint must adopt a sealing structure with a metal copper shell and PE or PVC insulation anti-corrosion layer to ensure the compactness of the lead seal during on-site construction, which effectively ensures the sealing and waterproof performance of the joint.

Mining network cables can also be customized according to user requirements (such as steel belt armor, steel wire armor)

Mining flame-retardant and explosion-proof network cable MHYV4 * 2 * 0.5, mining network cable, coal mine monitoring network cable, mining shielded network cable standard 568A:

Green white -1, green -2, orange white -3, blue -4, blue white -5, orange -6, brown white -7, brown -8

Standard 568B:

Orange white -1, orange -2, green white -3, blue -4, blue white -5, green -6, brown white -7, brown -8

In order to maintain compatibility, the EIA/TIA568B standard is commonly used to make mining network cables. Applying a wiring method in the entire network cabling, but with RJ-45 sockets at both ends of the network connection, whether using 568A or 568B standards, is feasible in the network. The order of twisted pair cables corresponds to the pin numbers of RJ45 connectors. A 10M Ethernet cable uses core wires numbered 1, 2, 3, and 6 to transmit data, while a 100M network card requires four pairs of wires. Due to the 10M network card being able to use Ethernet cables made in 100M format; Moreover, twisted pair cables provide four pairs of wires, so even if a 10M network card is used, the network cable is generally made in a 100M manner.

The standard requires that wires 1, 2, 3, 6, 4, 5, 7, and 8 must be twisted in pairs. This is because in the transmission of data, in order to reduce and alleviate external interference, the data sent and received are transmitted in a differential manner, that is, each pair of wires is twisted together to transmit a differential signal
