Safety is always an important consideration in cable engineering construction, and cable bridge plays the role of protecting cables and supporting load-bearing components in cabling engineering, so the importance of safety construction of cable engineering is obvious. However, after all, the application of cable bridge in our country is only about 10 years, and a few quality problems are inevitable. At this time, we need to have a certain understanding of the detection knowledge of cable bridge.

一、當電纜橋架本身產(chǎn)生質(zhì)量原因時(shí)，如有些電纜橋架產(chǎn)出現品質(zhì)差、加工粗糙、焊點(diǎn)不牢、防腐層附著(zhù)量不均勻和附著(zhù)力不夠、防火或耐火性能差等原因時(shí)，無(wú)論是供貨商還是采購商都需要對電纜橋架進(jìn)行檢測。

1. When the cable bridge itself produces quality reasons, such as poor quality, rough processing, weak solder joints, uneven adhesion and insufficient adhesion of anticorrosive coatings, poor fire resistance or fire resistance, both suppliers and purchasers need to test the cable bridge.

二、當電纜橋架在組裝交付后發(fā)生垮塌，或者短短幾年就出現嚴重腐蝕，當然 也可能存在工程選型不當造成重大變形、彎曲等缺陷的情況，這時(shí)，也需要我們對電纜橋架進(jìn)行檢測。

2. When the cable bridge collapses after assembly and delivery, or serious corrosion occurs in a few years, of course, there may also be serious deformation, bending and other defects caused by improper engineering selection. At this time, we also need to test the cable bridge.

Impact performance, anti-accelerated aging performance and so on.

由此我們可以看出，不同用途的電纜橋架檢測項目還是有區別的。一款高質(zhì)量的電纜橋架應該適應其布線(xiàn)工程所需要的各種荷載和檔距條件，滿(mǎn)足其力學(xué)性能要求，同時(shí)具備結構合理，對電纜起到有效的防腐、防火、耐火的保護。當然，這些都需要我們嚴格按照檢測標準里規定的技術(shù)指標來(lái)指導生產(chǎn)和施工，只有這樣才能真正保證電纜工程建設的性。

From this we can see that there are still differences in the detection items of cable bridge frames for different purposes. A high-quality cable bridge should meet all kinds of loads and spacing conditions required by its wiring project, meet its mechanical properties, and have reasonable structure, which can effectively protect the cable from corrosion, fire and fire. Of course, all of these require us to strictly follow the technical indicators specified in the test standards to guide production and construction, only in this way can we truly ensure the safety of cable engineering construction.
