技術在不斷的革新，企業(yè)也加強了對電纜橋架質(zhì)量的管理，從而進一步完善了它的生產(chǎn)工藝，為行業(yè)發(fā)展帶來了有利的條件，也給電纜施工和電纜安裝帶來了方便與益處。濟南電纜橋架母線槽跨接線連接要注意什么呢？

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?

橋架母線槽跨接線連接要注意：用抓墊、平墊或把噴塑橋架的漆刮掉再用平墊、彈簧墊壓緊。鍍鋅電纜橋架間連接板的兩端不跨接接地線，但連接板兩端不少于2個有防松螺帽或防松墊圈的連接固定螺栓（強標）。

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.

母線槽的選擇得從三點來講的，選擇母線槽得注意溫度的上升，這是可以保證載流能力的關鍵技術參數(shù)的，溫度的好壞就直接會影響到電能的損耗和壓降的。

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.

母線槽布線

Bus duct wiring

（1）母線槽布線搬適用于正常環(huán)境的室內(nèi)干燥和不易受機械損傷的場所明敷，但對母線槽有嚴重腐蝕的場所不應采用。

(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）同一回路的所有相線和中性線，應敷設在同一母線槽內(nèi)。同一路徑無防干擾要求的線路，可敷設于同一線槽內(nèi)，線槽內(nèi)電線或電纜的總截面（包括外護層）不應超過線槽內(nèi)截面的20％，載流導線不宜超過30根。控制、信號或與其相類似的線路，電線或電纜的總截向下應超過線槽內(nèi)截面的50％，電線或電纜根數(shù)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）母線槽垂直或傾斜安裝時，應采取措施防止電線或電纜在線槽內(nèi)移動。

(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）由母線槽引出的線路，可采用金屬管，硬質(zhì)塑料管、半硬塑料管、金屬軟管或電纜等布線方式。電線或電纜在引出部分不得遭受損傷。

(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）線糟應平整、無扭曲變形，內(nèi)壁應光滑、無毛刺。

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

（6）母線槽應可靠接地或接零，但不能作為設備的接地導體。

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

在母線的選擇上，應該有耐火材料的耐火時間和標準，當然，相對耐久性的選擇是好的。當選擇公交車，當然，也要考慮母線槽的使用，更多詳情就來我們網(wǎng)站http://m.ymmgjx.net咨詢了解吧！

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 http://m.ymmgjx.net Ask about it!
