The long-term operating temperature of cable conductors is 65 ℃
The bending radius of the cable is 6 times the diameter of the cable
Mining mobile cable 3 * 6+1 * 6-MY mining cable 380V
The MYP cable consists of three main cores with insulation shielding and a ground wire wrapped in a semi conductive rubber layer, which is twisted around the semi conductive rubber layer to form a cable.
It is safer to squeeze black chlorinated polyethylene rubber sheath or thick black chloroprene rubber sheath outside.
Conductive core: Made of soft copper wire, its performance complies with GB/T3956-1997.
Insulation: XJ-00A rubber according to GB7594.2-1987 is used.
Core identification: Insulation color separation identification is used, with the main core being red, green, and white.
Ground wire: covered with a semi conductive rubber.
Insulation shielding: Cover the insulation surface with a semi conductive tape.
Cabling: Three main cores and one ground wire are twisted in the right direction around a semi conductive rubber pad core to form a cable.
Sheath: XH-03A rubber according to GB7594.7-1987 is used. The oxygen index of the sheath rubber is ≥ 40.
The flame retardant performance of the finished cable meets the requirements of MT386-1995.
Cable marking: The surface of the cable is printed with the model, voltage, specifications, and manufacturer
