The porcelain and its bracket shall be firmly installed, the porcelain shall not be damaged, the porcelain bottles shall not be upside down, the spacing between the wire and the porcelain fixing points shall be correct, the bracket shall be painted completely, the wire shall be laid flat and orderly, and the two ends of the wire shall be fixed reliably with the beam, wall, floor, line, etc. which are fixed reliably with the porcelain and pass through the deformation joint of the protective tube
2.优良:在合格的基础上,瓷器排列整齐,间隔均匀,表面清洁的导线进入电气设备绝缘处理良好的弯曲和分支整齐。
2. Excellent: on the basis of qualification, the porcelain should be arranged in order and evenly spaced. The wires with clean surface should enter the electrical equipment, and the wires with good insulation treatment should be bent and branched in order.
三、护套配线施工。
3、 Sheath wiring construction.
1.合格:导线严禁扭曲、死亡、绝缘层损伤、护套断裂等缺陷。塑料护套线严禁直接埋入抹灰层。护套线铺设平坦整齐,通过固定可靠的梁、墙壁、地板、线路等有保护管的建筑物变形缝的导线两端固定可靠,保留适当馀量的护套线的连接牢固,包装牢固,绝缘良好,不损伤芯线的接头设置在接线箱和电气设备内
1. Qualified: no distortion, death, insulation damage, sheath fracture and other defects are allowed. It is strictly forbidden to directly embed the plastic sheath line into the plastering layer. The sheathed wire shall be laid flat and orderly, and the two ends of the conductor passing through the deformation joints of beams, walls, floors, lines and other buildings with protective pipes shall be fixed reliably. The remaining sheathed wire shall be firmly connected, packed firmly, insulated well, and the joint of the core wire shall be set in the junction box and electrical equipment
2.优良:在合格的基础上,导线的明铺部分与建筑物表面紧密接触的多个平行铺设间隔一致,分支和弯头整齐的配线箱位置正确,盖子整齐平整,导线进入配线箱或电气设备时留有适当的馀量。
