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. Identifi ed 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） 3.6/61.9/3.30.66/1.14 0.38/0.66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 fi nished cable sheath 九、 交货长度 delivery length 1、 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 fi nal 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
