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.

基带传输与频带传输基带传输是按照数字信号原有的波形（以脉冲形式）在信道上直接传输，它要求信道具有较宽的通频带。基带传输不需要调制解调，设备花费少，适用于较小范围的数据传输。基带传输时，通常对数字信号进行一定的编码，常用数据编码方法有非归零码NRZ、曼彻斯特编码和差动曼彻斯特编码等。后两种编码不含直流分量、包含时钟脉冲、便于双方自同步，所以应用广泛。频带传输是一种采用调制解调技术的传输形式。发送端采用调制手段，对数字信号进行某种变换，将代表数据的二进制“1”和“0”，变换成具有一定频带范围的模拟信号，以适应在模拟信道上传输；接收端通过解调手段进行相反变换，把模拟的调制信号复原为“1”或“0”。

Flame retardant cable, is refers to under specified test conditions, specimen was, after removed test of ignition, flame spread only in a limited range, residual sheep and burning in the finite cable to self extinguishing in the course of time. The fundamental characteristic is that it may burn out and not run in the case of fire, but it can spread fire. Generally speaking, in case of electric wire fire, it can be put in the local scope, not to produce spread, keep other kinds of equipment, avoid causing greater loss. The meaning of the flame retardant cable: under specified test conditions, samples were, in is removed after the fire, the spread of flame on the sample only in a limited range and the characteristic of self extinguishing, which has the ability of or delay the outbreak or spread of flame.
