电缆桥架相信大家都不会陌生，它是起到保护电缆的作用，当然在建造过程中是允许有所偏差的，但偏差是有规定的数值的，那么电缆桥架的尺寸偏差允许是多少呢？

　　Cable tray I believe everyone is familiar with, it is to protect the role of the cable, of course, in the construction process is allowed to have some deviation, but the deviation is a specified value, so how much is the allowable size deviation of the cable tray?

　　电缆桥架长度极限偏差：当长度小于2m时，极限偏差为2mm，当长度为2mm时，极限偏差为4mm。

　　Limit deviation of cable bridge length: when the length is less than 2m, the limit deviation is 2mm, when the length is 2mm, the limit deviation is 4mm.

　　电缆桥架宽度极限偏差：当宽度为400mm时，极限偏差为4mm，当宽度小于或等于400mm时，极限偏差为3mm。

　　Cable bridge width limit deviation: when the width is 400mm, the limit deviation is 4mm, when the width is less than or equal to 400mm, the limit deviation is 3mm.

　　桥架表面平整度公差：热镀锌桥架保护处理的平整度公差不大于8mmm，镀锌电缆桥架及涂层的平面度公差不大于4mmm。

　　Bridge surface flatness tolerance: the flatness tolerance of hot-dip galvanized bridge protection treatment is not greater than 8mmm, and the flatness tolerance of galvanized cable bridge and coating is not greater than 4mmm.

　　另外，在运输电缆桥架时应特别注意。外包装是保护山东省电缆桥架不受损坏的有效方法。一般要求外包装具有一定的抗压强度和抗穿刺性，以防止电缆桥架在正常运输和储存过程中完好无损。

　　In addition, special attention should be paid to the transportation of cable tray. Outer packing is an effective method to protect cable tray from damage in Shandong Province. It is generally required that the outer packaging has certain compressive strength and puncture resistance, so as to prevent the cable tray from being intact in the normal transportation and storage process.

济南电缆桥架在运输过程中，不得与易燃、易吸收、易污染的高温物品混合；装载时，禁止滚动和按压电缆槽。开车时尽量保持恒定的速度。不要快速刹车，以免电缆槽产生强烈振动。此外，注意不要与潮湿、高温、易燃和易污染的物品混合。

　　Ji 'nan cable tray in the process of transportation, shall not be mixed with flammable, easy to absorb, easy to pollute high temperature items; Do not roll or press the cable trough when loading. Try to maintain a constant speed when driving. Do not brake quickly to avoid strong vibration of cable groove. In addition, be careful not to mix with damp, high temperature, flammable and easily contaminated items.
