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.

三相电机六个引出线头分不清首尾端，首先必须先判断别三相绕组的首尾端，才能进行电动机的Y形和三角形联结，定子绕组首尾端判别方法如下：用万用表判别一种方法是：首先用摇表或万用表欧姆档找出三相绕组每相绕组的两个引出线头。做三相绕组的假设编号UUVVWW2.再将三相绕组假设的三首三尾分别连接在一起，用上万用表，用毫安档或微安档测量，1。用手转动电动机转子，若万用表指针不动，则假设的首尾端均正确。若万用表指针摆动（如所示），说明假设编号的首尾有误，应逐相对调重调，直到万用表指针不动为止，此时连在一起的三首三尾正确。

　　电缆的阻燃性能符合国家标准GB 12666.5的要求。耐火BV线在导体和绝缘层之间有一层耐火云母带，耐火BV线在着火的时候仍然可以正常使用一段时间啊，电缆缆的耐火性符合国家标准GB 12666.6的要求。

This is the General Pure Cable in UL for the UL1581. The experiment required several samples to be laid on a vertical 8 foot high bracket and 20 minutes with the specified 20KW ribbon spray lamp (70,000 BTU/Hr). for flame not to spread to the upper end of the cable and self-extinguishing. UL1581 is similar to iec 60332-3c except that the number of cable roots is different. There is no smoke concentration specification for commercial grade cables, which is generally only used for horizontal running of the same floor, but not for vertical wiring of the floor.
　　理论上RS485的传输距离能达到1200米，但实际应用中传输距离要小于1200米，具体长度受周围的环境影响。RVVP屏蔽电缆执行标准JBRVVP屏蔽电缆产品介绍：RVVP屏蔽电缆，额定电压300V/300V。

The total shielding structure can adopt copper wire and copper band combination shielding, copper wire braid shielding, copper wire braid shielding, copper wire braid shielding, etc. The shielded cable of this structure can resist electromagnetic induction, poor grounding and power line, reduce inductance and prevent the induction electromotive force from being too large.

伺服驱动器主要有三种控制方式；1.转矩控制：转矩控制方式是通过外部模拟量的输入或直接的地址的赋值来设定电机轴对外的输出转矩的大小，具体表现为10V对应5Nm的话，当外部模拟量设定为5V时电机轴输出为2.5Nm：如果电机轴负载低于2.5Nm时电机正转，外部负载等于2.5Nm时电机不转，大于2.5Nm时电机反转（通常在有重力负载情况下产生）。可以通过即时的改变模拟量的设定来改变设定的力矩大小，也可通过通讯方式改变对应的地址的数值来实现。

HYAT23 armoured communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and vulnerable to erosion area and design of telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. 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 polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter.
