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?

螺栓孔徑可比螺桿公稱(chēng)直徑大于1.5mm（螺桿直徑不應(yīng)大于M16）時(shí)或2mm（螺桿直徑不小于M20）時(shí)螺栓孔精度不應(yīng)低于H14級(jí)

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

螺栓連接孔的孔距允許偏差：同一組內(nèi)相鄰兩孔間≤±0.7mm；同一組內(nèi)任意兩孔間≤±1.0mm,相鄰兩組的端孔間≤±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.

在水平彎曲，垂直方向彎曲、分支和電纜梯架縮小寬度時(shí)，須使用制造廠的標(biāo)準(zhǔn)直角彎節(jié)，分支接頭，偏心縮節(jié)，直線(xiàn)縮節(jié)。

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、均勻、不起皮、無(wú)氣泡水皰。

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

附件表面防腐處理與橋架主體結(jié)構(gòu)相一致，電纜橋架的連接片開(kāi)孔數(shù)量及使用連接螺栓、平彈墊套數(shù)、規(guī)格應(yīng)滿(mǎn)足規(guī)范跨接連接相應(yīng)要求。橋架的蓋板材質(zhì)規(guī)格應(yīng)等同于電纜橋架。

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.

提供電纜橋架附件數(shù)量應(yīng)充足，并能滿(mǎn)足施工所需要求。電纜橋架的連接片及跨接銅編織帶均考慮5%的余量，螺栓栓帽、墊片考慮百分之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.

電纜橋架生產(chǎn)長(zhǎng)度為2米一節(jié)，長(zhǎng)度為2米時(shí)，偏差不應(yīng)大于2mm

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