Wire: annealed bare copper wire with diameter of, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9; Color the insulation line according to the full chromatographic standard. A single insulated wire is twisted in pairs at different pitch to minimize crosstalk and a specified chromatographic combination is used to identify pairs of wires. Cable core: the cable core structure is based on 25 pairs of cables. More than 25 pairs of cables are assembled according to the unit. Each unit is wrapped with the unit of specified chromatogram to identify different units. More than 100 pairs of cables plus 1% of the reserve pair. Shielding: the shielding layer is made of corrugated metal tape which is wrapped vertically on the outside of the cable core wrap belt and firmly bonded on both sides. The metal strip of the shielding layer is coated with plastic film to facilitate bonding with the sheath to prevent corrosion of the shielding layer. Protective sleeve: protective sleeve is black low density polyethylene, can use double protective sleeve according to the need.

万幸没有砸到人，但该事故也足以让人冷汗冒一身。就事故本身来说，不合规范处太多：没有正确记录相位顺序，没有通知相关人员整改情况，没有改后试运营，等等等等。但对“限位”的过分相信也是很重要的原因，确实，当时包括塔吊操作人员在内的许多人都说：“塔吊上装有限位啊。”虽然过份依赖“限位”可能会出问题，但话说回来，“限位”毕竟还是很重要的安全保护手段。那我们能不能让这份保护更加坚固呢？笔者思来想去，也只有应付的一个笨方法：加“保护限位”。
本厂主要生产自承式电缆适用于本地电信网的城市与乡镇电信线路，也适用于接入公用网的专用网线路。吊线和电缆用同一外护层，经济实用，安装敷设方便。在一31~C一61~C的环境条件下，自承式电缆的机械和电气性能保持不变。

MHYBV型弯曲半径不小于电缆直径的10倍。MHYVP型弯曲半径不小于电缆直径的10倍。MHY32型弯曲半径不小于电缆直径的15倍。煤矿用控制电缆允许的弯曲半径：对有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。
以380伏电动机为例说明。为了使电动机不过电流，就要维持磁通密度不变。在50HZ电源条件下，维持磁通密度不变的电压是(5O/60)X380=317伏。就是说只要把电源电压降至317伏，60HZ，380ⅴ的电动机在50HZ，380ⅴ的电源上使用不会发热。同时注意以下两个问题。电动机转速将降低17%左右。由于电压为额定电压的83%，降压后使用的功率仅为原电动机功率的83%。以上所述，在使用一些老电动机和进口设备(如美国，日本，韩国等)的电动机时希望对电工同行们有所帮助。
