技术在不断的革新，企业也加强了对电缆桥架质量的管理，从而进一步完善了它的生产工艺，为行业发展带来了有利的条件，也给电缆施工和电缆安装带来了方便与益处。 济南电缆桥架母线槽跨接线连接要注意什么呢？

With the continuous innovation of technology, the enterprise has also strengthened the management of cable bridge quality, thus further improving its production process, bringing favorable conditions for the development of the industry, and also bringing convenience and benefits to cable construction and cable installation. What should we pay attention to in the jumper connection of Jinan cable bridge bus duct?

桥架母线槽跨接线连接要注意：用抓垫、平垫或把喷塑桥架的漆刮掉再用平垫、弹簧垫压紧。镀锌电缆桥架间连接板的两端不跨接接地线，但连接板两端不少于2个有防松螺帽或防松垫圈的连接固定螺栓（强标）。

Attention shall be paid to the jumper connection of the bus duct of the bridge: use the grab pad, flat pad or scrape off the paint of the plastic-sprayed bridge, and then press the flat pad and spring pad tightly. The two ends of the connecting plate between galvanized cable trays shall not be connected to the ground wire, but the two ends of the connecting plate shall not be less than two connecting fixing bolts (strong standard) with locking nuts or washers.

母线槽的选择得从三点来讲的，选择母线槽得注意温度的上升，这是可以保证载流能力的关键技术参数的，温度的好坏就直接会影响到电能的损耗和压降的。

The selection of bus duct should be based on three points. Pay attention to the rise of temperature when selecting bus duct, which is the key technical parameter to ensure the current carrying capacity. The quality of temperature will directly affect the loss and voltage drop of electric energy.

母线槽布线

Bus duct wiring

（1）母线槽布线搬适用于正常环境的室内干燥和不易受机械损伤的场所明敷，但对母线槽有严重腐蚀的场所不应采用。

(1) The bus duct wiring is suitable for outdoor laying in indoor dry and non-mechanically damaged places in normal environment, but it should not be used in places with serious corrosion to the bus duct.

（2）同一回路的所有相线和中性线，应敷设在同一母线槽内。同一路径无防干扰要求的线路，可敷设于同一线槽内，线槽内电线或电缆的总截面（包括外护层）不应超过线槽内截面的20％，载流导线不宜超过30根。控制、信号或与其相类似的线路，电线或电缆的总截向下应超过线槽内截面的50％，电线或电缆根数下限。

(2) All phase and neutral wires of the same circuit shall be laid in the same bus duct. Lines with no anti-interference requirements in the same path can be laid in the same trunking. The total cross-section of wires or cables in the trunking (including the outer protective layer) should not exceed 20% of the cross-section in the trunking, and the number of current-carrying conductors should not exceed 30. For control, signal or similar lines, the total cross section of wires or cables shall exceed 50% of the cross section in the trunking, and the lower limit of the number of wires or cables.

（3）母线槽垂直或倾斜安装时，应采取措施防止电线或电缆在线槽内移动。

(3) When the bus duct is installed vertically or obliquely, measures shall be taken to prevent wires or cables from moving in the trunking.

（4）由母线槽引出的线路，可采用金属管，硬质塑料管、半硬塑料管、金属软管或电缆等布线方式。电线或电缆在引出部分不得遭受损伤。

(4) The lines led out from the bus duct can be wired in metal pipes, rigid plastic pipes, semi-rigid plastic pipes, metal hoses or cables. The wire or cable shall not be damaged at the outgoing part.

（5）线糟应平整、无扭曲变形，内壁应光滑、无毛刺。

(5) The wiring duct shall be flat without distortion and deformation, and the inner wall shall be smooth without burr.

（6）母线槽应可靠接地或接零，但不能作为设备的接地导体。

(6) The bus duct shall be reliably grounded or connected to neutral, but it cannot be used as the grounding conductor of equipment.

在母线的选择上，应该有耐火材料的耐火时间和标准，当然，相对耐久性的选择是好的。当选择公交车，当然，也要考虑母线槽的使用，更多详情就来我们网站 //www.comprepyme.com咨询了解吧！

In the selection of bus, there should be the fire resistance time and standard of refractory materials. Of course, the selection of relative durability is good. When choosing buses, of course, we should also consider the use of bus ducts. For more details, please visit our website //www.comprepyme.com Ask about it!
