Model specifications and scope of mine control cable products: Model specifications of the control cable for mining use: MKVV,MKVVP, mkvvvvvvvvvvp2-10mm2,2-61 cores are applicable to the weak current control system or mkvvvv22 of the strong electromagnetic field interference area. MKVV20 0.5-10mm2,4-61 core mkvvv32, mkvvvvv30 0.5-10mm2,7-61 core MKVVR 0.5-6mm2,2-61 core MKVRP 0.5-4mm2,2-61 core mkvvvvvvp22, mkvp2-221.5-10mm2, 4-22 core mkvp2, 1.5-10mm2 Is mainly used for 500 kv substation and power distribution device and strong electromagnetic interference zone MKVV - 1, MKVV22 0.5 was 10-1, 4, 2-61 core features: coal mine with control cable conductor long-term allowed working temperature is 70 ℃, the cable temperature under installation should not below 0 ℃. Permissible bending radius of control cables used in coal mines: for cables with armored or copper band shielding structures, the bending radius should not be less than 12 times of the outer diameter of the cables. For soft cable with shield layer structure, it should be no less than 6 times the outer diameter of the cable. The cable without armor layer should not be less than 6 times the outer diameter of the cable.
