当采用阿拉伯数字 编码时， 4芯电缆动力线芯为1、 2、 3， 地线芯为0 2、 电缆识别标志： 井下用不同电压等级电缆的护套宜采 用不同的识别颜色， 见下表：Identified mark of insulated core: using color OR printing numbers on the surface of insulated core. If you use color to identify, the insulated color of single core cable is red or white. Power core color of c able with 4 cores is red, white, light blue and black for earthing conductor. If you print numbers on the surface of insulated core, power core of cable with 4 cores is 1, 2, 3 and 0 for earth- ing conductor.Identified mark of cable: Different cable sheath color will be used to identify cable under well with different voltage degree. Please see the following table.U0/U（kV）3.6/61.9/3.30.66/1.140.38/0.66及以下 0.38/0.66 or lower护套颜色 Sheath color红 red黑 black黄 Yellow黑 black成品电缆护套表面至少应明显印有： 制造厂名、 型号规 格、 电压、 煤安标志的内容。

Manufacturer, type, voltage and coal mine safety mark etc. will be clearly printed on the surface of finished cable sheath九、 交货长度delivery length1、 电缆根据双方的协议长度交货 2、 无协议时， 按产品标准规定： 最小短段长度为40米，短段长度应不超过总长度的10% 3、 长度计量误差不超过±0.5%Delivery length of cable depends on final both agree- ments. If there is no final agreement, the cable no shorter than 40 meters is allowed for delivery, which accounts for no more than 10% of the total length. Length error of cable is no more than ±0.5%.114。
