As the market changes, bridges have spread all over the market, and there are many bridge classifications. And this product will be used everywhere in our life. Now, the Suxin cable tray manufacturer will give you a detailed introduction to the cable tray technology. What are the requirements?

螺栓孔径可比螺杆公称直径大于1.5mm（螺杆直径不应大于M16）时或2mm（螺杆直径不小于M20）时螺栓孔精度不应低于H14级

When the nominal diameter of the comparable bolt hole diameter is greater than 1.5mm (the screw diameter shall not be greater than M16) or 2mm (the screw diameter shall not be less than M20), the bolt hole accuracy shall not be lower than grade h14

螺栓连接孔的孔距允许偏差：同一组内相邻两孔间≤±0.7mm；同一组内任意两孔间≤±1.0mm,相邻两组的端孔间≤±1.2mm。

Allowable deviation of bolt connection hole spacing: between two adjacent holes in the same group ≤± 0.7mm; Between any two holes in the same group ≤± 1.0mm, and between end holes of two adjacent groups ≤± 1.2mm.

在水平弯曲，垂直方向弯曲、分支和电缆梯架缩小宽度时，须使用制造厂的标准直角弯节，分支接头，偏心缩节，直线缩节。

When bending horizontally, bending vertically, branching and reducing the width of cable ladder, the manufacturer's standard right angle bending joint, branch joint, eccentric shrinkage joint and linear shrinkage joint must be used.

防火漆要求平整、光滑、均匀、不起皮、无气泡水疱。

The fireproof paint shall be flat, smooth, uniform, free from peeling and blisters.

附件表面防腐处理与桥架主体结构相一致，电缆桥架的连接片开孔数量及使用连接螺栓、平弹垫套数、规格应满足规范跨接连接相应要求。桥架的盖板材质规格应等同于电缆桥架。

The surface anti-corrosion treatment of accessories shall be consistent with the main structure of cable tray. The number of openings of connecting pieces of cable tray, the number and specification of connecting bolts and flat elastic pads shall meet the corresponding requirements of specification jumper connection. The material specification of the cover plate of the bridge shall be the same as that of the cable bridge.

提供电缆桥架附件数量应充足，并能满足施工所需要求。电缆桥架的连接片及跨接铜编织带均考虑5%的余量，螺栓栓帽、垫片考虑百分之10%的余量。

The number of cable tray accessories provided shall be sufficient and can meet the requirements of construction. 5% allowance shall be considered for the connecting piece and jumper copper braided belt of cable tray, and 10% allowance shall be considered for bolt cap and gasket.

电缆桥架生产长度为2米一节，长度为2米时，偏差不应大于2mm

The production length of cable tray is 2m. When the length is 2m, the deviation shall not be greater than 2mm
