Mining the use of power cables:
This product is for use in mines rated voltage 1KV and below fixed laying cables, power transmission applicable to coal mine.
Mine conditions of use with power cables:
Wire core long-term allowable working temperature to 65 ° C, cable laying temperature of not less than 0 ° C, the cable allows the minimum bend radius of 15 (D + d) ± 5%.
The MVV cable, cable MVV22, MYJV cable, cable MYJV22, MYJV32 mine apply to use of power cable products rated voltage 0.6/1KV and the following transmission and distribution lines in the coal mine.
The MVV PVC insulated PVC sheathed mine power cables for use: Energy transmission line, but can not bear external mechanical forces
MVV22 coal with PVC insulated, steel tape armored PVC sheathed power cable use: Energy transmission lines, able to bear external mechanical forces
MVV32 coal with PVC insulated steel wire armored PVC sheathed power cable Usage: Energy transmission lines, can withstand a certain force
MVV42 PVC insulated thick steel wire armored, PVC sheathed mine power cables for use: Energy transmission lines, able to withstand greater pull

MYJV42 cross-linked polyethylene insulation, thick steel wire armored, PVC sheathed mine power cables use: Energy transmission lines, able to withstand greater pull
Mine power cable conductor outsourcing high-quality insulating materials, and a variety of cables of the protective layer. Mining the function of the power cable is long-term safe and reliable transmission capacity of electricity. Mine power cable has the following characteristics:
(1) should be able to long withstand high or even very high, high operating voltage, the cable should have very good electrical insulation properties;
(2) is able to carry a lot of current (hundreds or even thousands of amperes), this cable should have good thermal aging resistance (heat resistance) and heat dissipation;
(3) The cable sheath should have a variety of structures to protect the insulating layer to adapt to the needs of a variety of laying environment (underground water pipe trench tunnels);
(4) due to changes in the electrical systems and electrical equipment, cables have a lot of varieties, specifications, and to adapt to different transmission capacity, number of phases, voltage, and laying environment. There are DC-DC transmission system used in mine power cable.
