铝合金桥架托盘或梯架的宽度和高度应根据电缆的数量、直径、结构层次和电缆载荷来选择。敷设在铝合金桥架上的电缆应考虑载流量的影响，载流量修正值应按规定取值。托盘、梯架中电缆的装载率不应超过下列规定：电力电缆40%-50%，控制电缆50-70%，工程开发余量宜留出10%-25%。

The width and height of aluminum alloy bridge trays or ladders should be selected based on the number, diameter, structural hierarchy, and cable load of the cables. The cable laid on the aluminum alloy bridge should consider the influence of current carrying capacity, and the correction value of current carrying capacity should be taken according to the regulations. The loading rate of cables in trays and ladders should not exceed the following regulations: 40% -50% for power cables, 50-70% for control cables, and 10% -25% for engineering development allowance.

铝合金桥架的托盘和梯架直通单件长度，可根据跨距，吊架的载荷和施工条件来选择。在多层布局的情况下，层间净距不应小于150mm；选择弯道半径的依据是电缆允许的弯道半径。配件规格应符合工程布置条件，并与托盘、梯架配合使用。支架规格的选择，应根据托盘、梯架的规格，层数，跨距等情况进行配置。

The length of the tray and ladder of the aluminum alloy bridge frame can be selected according to the span, hanger load, and construction conditions. In the case of multi-layer layout, the clear distance between layers should not be less than 150mm; the basis for selecting the bending radius is the allowable bending radius of the cable. The specifications of accessories should comply with the engineering layout conditions and be used in conjunction with pallets and ladders. The selection of bracket specifications should be based on the specifications, number of layers, span, and other factors of the tray and ladder.

铝合金桥架托盘及梯架表面采用阳出彩化，喷漆，双层保护，使用寿命长达15年，做到免维护。新防风锁，防台风性能达到10个等级。全部配件均采用优良不锈钢，持久清洁美观。

The surface of the aluminum alloy bridge tray and ladder frame is anodized, painted, and protected with double layers, with a service life of up to 15 years and maintenance free. New windproof lock, with typhoon resistance performance reaching 10 levels. All accessories are made of high-quality stainless steel, which is long-lasting, clean, and aesthetically pleasing.
