7.6.3.4 电缆敷设
电缆敷设前,首先对电缆的长度、型号、规格与设计图纸进行核对,然后进行绝缘测试,敷设的电缆外表无纹拧、铠装压扁、护套断裂和表面严重划伤等缺陷.
电缆直埋时采用铺砂盖砖或按设计要求做好防护.回填土轻夯.电缆敷设穿过路基时采用穿钢管保护,电缆穿管时,先打磨钢管口,并在管口加衬垫,以免刮破电缆外护套.所有的电缆敷设完毕,均加标志牌标识,并按照规范要求埋设电缆标桩.
7.6.3.5 电缆头制作
制作前先对电缆及电缆头材料进行检查,核对芯数、线芯截面等正确无误后方可开始电缆头制作.制作前对电缆进行绝缘测试,合格后方可开始制作.
电缆终端头的出线保持必要的电气间距,带电引上部分及至接地部分的距离符合规范要求.电缆头制作时选择干燥、洁 净的环境,防止电缆受潮或污秽侵入电缆绝缘层.
电缆头制作完成后,必须进行直流耐压试验和泄漏电流试验,以确保电缆头施工质量.

The laying of cables,first of all on the length of the cable,models,specifications and design drawings for cross-checked,and testing for insulation,exterior cable-free screw pattern,sheathed squash,jacket and fracture surface scratch,and other serious defects.
Buried cable used to build sand brick shop or by design requirements to do a good job protection.Back fill light tamping.The laying of cables across the road used to wear protection of steel pipes,cables through tubes,the first I polished steel tube and pipe in mouth lining increases,so as not to Guapo outside the cable jacket.All completed the laying of cables,plus all signs logo,and in accordance with the specifications laid cable stake.
7.6.3.5 the first cable production
Prior to the production of cables and cable materials in the first inspection,check the core,core-line section,and so on are correct before the beginning of the first cable production.Pre-production testing of cable insulation,qualified before the beginning of production.
Cable terminations in the first round of the need to maintain the distance between the electric,charged onto some part of the ground until the distance in line with regulatory requirements.The production of cables for the first time to choose dry,clean environment to prevent the cable damp or dirty invasion cable insulation.
Upon completion of the first cable production,the need for DC voltage testing and leakage current test to ensure the quality of construction in the first cable.
