 ZRMKVVMKVV MKVVP Mining control cable 1. Implementation standard for mining control cables: MT818-1999 2. Application of coal mine control cables: This product is suitable for connecting electrical instruments in control monitoring circuits, protection circuits, and distribution devices with AC rated voltage U0/U of 450/750V and below. 3. The application of control cables for coal mines is MKVV MKVVP MKVVRP MKVVR 0.5-10mm 22-61 core, which is suitable for weak current control systems or strong electromagnetic field interference areas. MKVV22 MKVV32 0.5-10mm 22-61 core is suitable for strong electromagnetic field interference areas. 4. Main technical performance and indicators: DC resistance of the conductor at 20 ℃ is Ω/km 0.75mm ² ≤ 24.5 1.0mm ² ≤ 18.1 1.5mm ² ≤ 12.1 2.5 mm ² ≤ 7.41. The insulation resistance of the cable core at 20 ℃ is M Ω. km ≥ 60. It can withstand AC power frequency voltage of 3.0KV/5min. The long-term allowable working temperature of the conductor is -40~+50 ℃; When the average maximum relative humidity is ≤ 95 (+25 ℃), the allowable temperature for attachment and installation should not exceed -10 ℃. Usage characteristics: The long-term allowable working temperature of the control cable conductor used in 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 a shielding layer structure, it should not be less than 6 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. |
