Mining cable MCP3 * 6+1 * 6

MYPTypeMYPCType cable is a local communication cable designed for telephone exchange areas and trunk lines, which can be used to transmit audio signals and integrated business digital networks2B+DDigital signals with speeds and below can also be used for transmission2048Kbit/sThe digital signal or150KHThe following analog signals.

MYPType series cables are mainly used for pipeline laying and can also be used for overhead, but they require hanging wires and are suitable for underground (pipeline, direct burial) and overhead laying.

MYP53The type cable improves the mechanical strength and corrosion resistance of the cable, and can be laid in any way, making it more suitable for direct burial in rocky areas. The operating temperature is:-30℃～60℃.

Structural characteristics:MYPThe communication cable in the city adopts full spectrum insulation and aluminum-plastic composite sheath (i.e. the longitudinal shielding aluminum tape of the cable is bonded to the sheath to form a sealed protective layer)Mining cable MCP3 * 6+1 * 6

Structural characteristics of mining rubber sheathed cables:

one:The flexibility requirements for conductive wire cores are for drill cables and mining machine cables; The following measures are taken for the wire structure:

1.Using softer small-diameter copper single wires, bundled and twisted at small intervals. The bending and twisting properties of the entire cable are also affected by the insulation and sheath structure, so it cannot be assumed that the finer the single wire, the smaller the pitch, the better.

2.The use of co directional bundle twisting and compound twisting can improve flexibility.

3.In order to facilitate the relative sliding of wires in the insulation layer and facilitate installation and maintenance. The single wire of drill cables and small section mining machine cables should be tinned, and the large section mining machine cables should be insulated with paper tape outside the wire.

two:insulating layer Require sufficient electrical insulation performanceMining cable MCP3 * 6+1 * 6

1.Adopting a glue content of not less than one percent35The rubber

2.The insulation thickness is thicker than that of general rubber sheathed cables

3.Using rubber with good electrical properties and adopting good extrusion technology (such as extrusion vulcanization continuous production line)

The use of semiconducting rubber as a layer should ensure that its transition resistance meets the standard requirements to ensure reliable operation of the relay protection system in case of accidents.
