Usage characteristics: The allowable working temperature of the control cable conductor for coal mines is 70 ℃, and the cable laying temperature should not be lower than 0 ℃. The allowable bending radius for control cables used in coal mines: For cables with armor or copper tape shielding structures, it should not be less than 12 times the outer diameter of the cable. For flexible cables with shielding layer structures, they should not be small
Six times the outer diameter of the cable. For unarmored cables, the diameter should not be less than 6 times the outer diameter of the cable.
