| 水电改造的电路材料 Circuit materials for hydropower transformation 1、家装水电二次改造强电线路需采用经过国家强制3C认证标准的BV（聚氯乙烯绝缘单芯铜线）导线；一般不采用护套多芯线缆，如出现多芯与单芯线缆对接情况，必需对接头处进行涮锡处理。 1. The BV (PVC insulated single core copper wire) wire which has passed the national compulsory 3C certification standard shall be used for the secondary transformation of domestic hydropower lines; generally, the sheathed multi-core cable is not used, and if the multi-core and single core cable are connected, the joint must be tinned. 2、强电材料采购遵循不同用途线缆采用分色原则，防止不分色造成后期维护不方便，具体表现在：零线一般为蓝色，火线（相线）黄、红、绿三色均可采用，接地线为黄绿双色线。保证线色的统一分配有利于后期维护工作。 2. The procurement of strong current materials shall follow the principle of color separation for cables of different purposes to prevent the inconvenience of later maintenance caused by color separation. The specific performance is that the zero line is generally blue, the live line (phase line) can be yellow, red and green, and the ground wire is yellow green double color. To ensure the uniform distribution of line color is conducive to the later maintenance work. |
