梯形电缆桥架横档标准

梯形电缆桥架一般由底板、横档、盖板和连接片组成，横担通过焊接固定在两边的侧板上，侧板加横档成为桥架的主体结构，原来桥架横档都是桥架生产厂家自己生产，JB/T 10216-2013 电控配电用电缆桥架标准（下面简称2013标准）中对于横档的标准要求作了相关规定。下面北京京运伟业电缆小编就给大家具体介绍一下：  

标准1

横档与横档之间的距离一般为不应大于300mm，距离再宽的话，就无法满足桥架的安全载荷标准要求，参照2013桥架标准，一节2米的梯式桥架如果高度为100mm，则其每米载荷的标准要求为1000N，如果为高度为200mm,则其每米的标准要求载荷为3100N。

标准2

桥架横档的厚度应该与桥架侧边的厚度为同一等级，例如桥架侧边板材的厚度标准为1.5mm，则桥架横档板材的厚度标准也应该为1.5mm，当然也可以选择2.0mm厚一等级，电缆桥架制造厂家从成本方面考虑，很少会用厚一等级的横档。

标准3

桥架横档的宽度一般为40mm,敷设在梯式桥架上的电缆与横档的接触宽度不要小于25mm，这是2013标准中关于接触面积的要求，如果接触面积过小，会导致桥架单个横档的承载载荷过大，导致横档挠度值过大发生弯曲变形，焊的不好的话这个横档还会掉落。

Trapezoidal cable bridge is generally composed of a bottom plate, a rail, a cover plate and a connecting piece. The cross arm is fixed on the side plate on both sides by welding. The side plate plus the rail becomes the main structure of the bridge. JB/T 10216-2013 Electrically controlled distribution cable tray standard (hereinafter referred to as 2013 standard) has made relevant provisions for the standard requirements of the transverse. The following Beijing Jingyun Weiye cable xiaobian will give you a specific introduction:

Standard 1

The distance between the crossbar and the crossbar should not be greater than 300mm. If the distance is wider, it cannot meet the safety load standard requirements of the bridge. Referring to the 2013 bridge standard, a 2 meter ladder bridge if the height is 100mm, the standard requirements of the load per meter are 1000N. If the height is 200mm, the standard load per meter is 3100N.

Standard 2

The thickness of the bridge rail should be the same grade as the thickness of the bridge side, for example, the thickness standard of the bridge side plate is 1.5mm, then the thickness standard of the bridge rail plate should also be 1.5mm, of course, you can also choose a grade of 2.0mm thick, cable bridge manufacturers from the cost point of view, rarely use a grade of thick rail.

Standard 3

Bridge generally is 40 mm, the width of rail laying on the ladder type cable on the bridge and the rail contact width is not less than 25 mm, this is about the contact area in 2013 standard requirements, if the contact area is too small, can lead to bridge the bearing load of a single rail is too big, cause a bending deformation of the rail deflection value is too large, the rail welding is not good words will fall off.
