电缆桥架镀锌及外观要求

　　Galvanization and appearance requirements for cable trays

　　要求：

　　requirement:

　　①热浸镀锌桥架镀层表面应均匀，无毛刺、过烧、挂灰、伤痕、局部未镀锌。每节桥架上直径小于2mm的漏镀点， 每米不超过2个，且在任一1m?面积内不得有两个及2个以上漏镀点。不得有影响安装的锌瘤。

　　① The surface of the hot-dip galvanized bridge coating should be uniform, free of burrs, overburning, dust hanging, scars, and partial lack of galvanizing. There shall be no more than 2 plating leakage points on each bridge with a diameter less than 2mm per meter, and there shall be no two or more plating leakage points within any 1m ? area. There must be no zinc nodules that affect installation.

　　②电镀锌的锌层表面应光滑均匀，致密。不得有起皮、气 泡、花斑、局部未镀、划伤等缺陷。

　　② The surface of the zinc layer of electroplated zinc should be smooth, uniform, and dense. There shall be no defects such as peeling, bubbles, flower spots, partial uncoated areas, scratches, etc.

　　③喷塑层的表面应平整、光滑、均匀、不起皮、无起皱、 气泡等缺陷。

　　③ The surface of the spray coating should be flat, smooth, uniform, without peeling, wrinkling, bubbles or other defects.

　　④螺纹的镀层应光滑，螺栓连接件应能拧入。

　　④ The coating of the thread should be smooth, and the bolt connection should be able to be screwed in.

　　⑤桥架焊缝表面均匀，不得有漏焊、裂纹、夹渣、烧穿、 弧坑等缺陷。

　　⑤ The surface of the bridge welding seam should be uniform and free of defects such as missed welding, cracks, slag inclusion, burn through, arc craters, etc.

　　⑥桥架外型尺寸应符合图纸及工艺要求，表面应无变形、 划伤、开裂现象。

　　⑥ The external dimensions of the bridge should comply with the drawings and process requirements, and the surface should be free of deformation, scratches, and cracking.

　　⑦桥架两对边应平行，两侧边对底边应垂直，断面形状端 正，无弯曲、裂纹、边缘毛刺等缺陷。

　　⑦ The two sides of the bridge should be parallel, and the two sides should be perpendicular to the bottom edge. The cross-sectional shape should be straight and free of defects such as bending, cracks, and edge burrs.

　　⑧桥架内侧应平整光滑，无损伤电缆绝缘的凸起尖角。

　　⑧ The inner side of the cable tray should be flat and smooth, without any protrusions or sharp corners that damage the cable insulation.

　　⑨桥架端头毛刺高度不应大于0.1mm。⑩桥架直线段每米偏差应不大于1mm，垂直度（底边对侧 边）允许偏差1/200。

　　⑨ The height of burrs at the end of the bridge should not exceed 0.1mm. The deviation per meter of the straight section of the bridge should not exceed 1mm, and the allowable deviation for verticality (bottom edge to side edge) is 1/200.
