This product is suitable for AC rated voltage u0/u 450/750V and below control monitoring circuit, protection circuit and power distribution equipment as connection line.
The long-term use of conductor temperature 70°C allowed to work, cables temperature shall not be lower than 0 °C. With control cable allowed coal mine bending radius of armoured or copper tape screened structure of cable should be no less than 12 times of cable diameter. For screened flexible cable, should be not less than 6 times of cable diameter. For those without armoured layer of cable should be no less than 6 times of cable diameter.
Mine armoured control cable specification and scope:
MKVV, MKVVP, MKVVP2 (0.5, 10, 2-61 was the core) apply to weak current control system or strong electromagnetic interference area
MKVV22, MKVV32 (0.5, 10) 4-61, was the core
MKVVR (0.5-6) 2-61 was the core
MKVVRP (0.5 to 4) 2-61 was the core
MKVVP22, MKVVP2-22 (1.5, 10) 4-61 was the core
MKVVP2-22 (1.5, 10) 4-61 core was mainly used for substation of 500 KV power plant and power distribution equipment and strong electromagnetic interference area.
