仲春KVVRP37X0.75控制电缆格西工
电动葫芦电缆-电动葫芦专用电缆-电动葫芦带丝绳专用电缆用途：本产品具有柔软、耐磨、防油等特性，线旁附钢丝绳，增强抗拉力。适用于交流额定电压0.6/1KV及以下的行车、台车、传输机械等移动电器用动力传输线及控制、照明、通讯线路，本产品已广泛应用于冶金、电力、船舶、港口等行业。
电缆导体的充许长期高工作温度为70℃。电缆敷设时环境温度应不低于0℃，若环境温度低于0℃时，应对电缆进行预热。电缆的推荐充许弯曲半径如下：无铠装电缆，应不低于电缆外径的6倍；铠装或铜带屏蔽电缆，应不低于电缆外径的12倍；屏蔽软电缆，应不低于电缆外径的6倍。
所谓的差分信号是指一根线以正电平方式传输信号，另外一根线以负电平方式传输同一信号，当线路中出现干扰信号时，其对两根线的影响是相同的，因而在接收端还原差分信号时就可以屏蔽掉该干扰信号（可以理解为差分的两路信号执行减运算）。
生产规格：对数2对—300对，导体直径为：0.4、0.5、0.6、0.7、0.8（mm）电缆对数型号（0.5）型号（0.5）5对HPVV5x2x0.5HPVVP5x2x0.510对HPVV10x2x0.5HPVVP10x2x0.520对HPVV20x2x0.5HPVVP20x2x0.。
适用于市内、近郊及局部地区架空或管道敷设线路中，也可直埋。3、对绞：把二根不同颜色的绝缘单线按照不同的节距扭绞成对，以大限度地减少串音，并采用规定的色谱组合以便识别线对。4、缆芯：由苦干个基本单位或超单位绞合而成，每个单位都用规定色谱扎带绕扎，以便识别不同单位。
一位LED数码显示单元电路如所示。WR与A8(P2.0)相或提供74LS273的时钟信号，当执行“MOVX@DPTR，A”指令时，地址信息由DPTR寄存器确定，会出现有效的写信号WR，只有当地址A8为满足“0”时，写信号才可以作为74LS273的时钟信号输入，完成数据锁存。P2口为A8～A15的8位地址线，很容易扩展到8只LED数码管，WR信号分别与A8～A15按或关系连接，每位地址线均为低电平有效，即可实现8个有效地址。
把单根绝缘线按不同节距扭绞成对，以大限度地减少串音，并采用规定的色谱组合，以便识别线对。缆芯：:缆芯结构以25对为基本位，超过25对的电缆按单位组合，每个单位用规定色谱的单位扎带包扎，以便识别不同单位。
Computer cable sheath: one, the scope of application: this product is fit for ac rated voltage up to and including 300/500 v or 1000 v dc electronic computer network and automation control system of signal transmission, high anti-jamming performance re of the detection device and instrument connections. Second, implement standard SPTL/ three, use features: 1. The cable conductor of long term working temperature should be allowed no more than 70 ℃, in the process of using cable should prevent high temperature radiation or contact; Ambient temperature under installation should not below 0 ℃. 2. Allowable bending radius of cable laying and installation: non-armoured layer cables shall be no less than 6 times the outer diameter of the cable; The armoured or shielded cable shall not be less than 12 times the outer diameter of the cable. The soft cable of shield layer structure should not be less than 6 times the outer diameter of the cable.
20世纪30年代中后期始有标志飞行场地或跑道边界的灯具。1953年以后，大型快速的涡轮螺旋桨飞机和喷气式飞机相继问世，驾驶员需要在更远的地方发现跑道，航空运量的不断增长也对飞行安全和航班正常提出了更高的要求。
Main characteristics of the mine cable fire with fire temperature in 600 ℃ ~ 8000 ℃, the fire cases, the cable will soon lose insulating ability, thus cause the secondary electrical accidents such as short circuit, causing a greater loss. The wire and cable have greater overload capacity under the specified allowable load flow. In a short circuit, the wire and cable will instantly cause the insulation to melt and ignite the surrounding area.

6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible.
