Product introduction - mine control cable MKVV mine control cable MKVVR mine control cable shielding control cable MKVV32 MKVVP mining mine control cable MKVVRP mine shielding control cable for mine control cable MKVV22 mine flame-retardant control cable for mine monitoring control cable for mine cable type MKVV, MKVV22, MKVV32, MKVVR, MKVVP, MKVVRP 1, mine control cable standards and specifications: MT818-1999-2, flame-retardant control cable for mine purposes: This product is suitable for the control and monitoring circuit with rated ac voltage u0/u of 450/750v or below and the connecting line of the protection circuit and the electrical instrument in the distribution device. 3. 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.

Flame-retardant cables are characterized by a delay in the spread of flame along the cable so that the fire does not expand. Because of its low cost, it is a kind of cable widely used in fireproof cable. Under the condition of single cable or into a bunch of laying, cable to know when the spread of flame can be controlled within a certain range, so it can avoid fire spreading combustion and lining major disasters, which cable line of fire prevention level.

  这种区别是由历史原因造成的,而不是由于技术原因或生产厂家。同轴电缆的这种结构,使它具有高带宽和极好的噪声抑制特性。同轴电缆的带宽取决于电缆长度。1km的电缆可以达到1Gb/s~2Gb/s的数据传输速率。

对含有大电容的设备,测量前应先进行放电,测量后也应及时放电,放电时间不得小于2min,以保证将电放完。测量前,应将被测电气设备和兆欧表的测量处擦拭干净,并保持被测物表面的清洁,尽量减少接触电阻,确保测量结果的准确性。兆欧表的接线。兆欧表有三个接线端钮,分别标有L(线路)、E(接地)和G(屏蔽),使用时应按测量对象的不同来选用。当测量电气设备对地的绝缘电阻时,应将L接到被测设备上,E可靠接地即可。
