7.6.3.4 the laying of cables
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. 7.6.3.4 the laying of cables
