The cross section of the control cable is generally no more than 10 square meters, and the power cable is mainly used to transport power, which is generally large. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet (normal manufacturer can produce range), again big cross section of the general factory is relatively less, you can do and control cable section generally small, generally not more than 10 largest square, tell from some cable, power cable according to the request of power grid, most commonly for five core, and control cable transmission control signal, some more, according to the standard terms of more than 61 core, but also can produce according to user re

一位电工伙伴技能升级方向的询问，他说：“电像空气一样已然成为日常中不可或缺的东西，在炎热的酷暑不分昼夜发生停电时，你们或许不知，你们在闷热里烦躁不堪，而我汗流浃背的赶工当中。恢复用电那刻，有成就感及无奈感，摸了摸见底的裤兜，每天过着精打细算且还入不敷出的生活”。为了生活及这份成就感留存，技术层面在现下阶段已是遭遇到瓶颈，可是又不知道该往哪方面入手较为合适，所以想问问这边能给出什么建议之类的。那么针对以上问题，提点个人对这类型岗位技能升级的看法：在任一行业做到人上人，软技能与硬技能是兼备的，技能升级就是一个绕不过去的坎。

Main products are: mine cable MHYV, MHY MHYA32, MHY32, MHYVP, MHYVR, MHYVRP, MKVV, MKVV22, MKVV32, MKVVR, MKVVP etc., all kinds of products are all in the coal Ann mark certificate and complete specifications, the major products are widely used in coal mine and coal mine monitoring and control. The products are used in dozens of coal groups and mines, which have been highly praised.

Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyethylene or polyvinyl chloride thin sheath. Sheath thickness may depend on the basic cable outer diameter. 4, identification and marking: cable appearance with permanent identification mark, tag, at no more than alternate 1 m intervals between 5, sheathed communication cable tag contents are: the diameter of wire, wire on the , type of cable, length, factory name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical re of the basic cable. 7. Cable length: mechanically protected cable is manufactured according to the standard length of the corresponding basic cable

三相异步电动机的反接制动，控制电路图如下：（，电动机反接制动电路）从上图可看出，其主电路和正反转电路类似。不同的是，由于反接制动时，旋转磁场的相对速度较高，差不多为启动时的两倍，定子电流也很大，在反接制动电路中增加了限流电阻R。速度继电器的触头ks串接在控制电路中。电机反接制动过程分析：当电动机转速升高后，速度继电器的动合触点KS闭合，为反接制动接触器KM2接通做准备。停车时，按下复合按钮SB1（其动断触点断开，动合触点闭合），接触器KM1断电释放，动断辅助触点KM1闭合，接触器KM2线圈得电，KM2主触点闭合（同时KM2自锁触点闭合自锁，动断触点KM2断开，对KM1联锁），电动机反接制动。
