在電氣工程領(lǐng)域，電纜橋架堪稱電力與信號(hào)傳輸?shù)?“生命線載體”，其質(zhì)量?jī)?yōu)劣絕非小事，劣質(zhì)電纜橋架帶來(lái)的麻煩，足以讓工程陷入困境，甚危及生命財(cái)產(chǎn)。

　　In the field of electrical engineering, cable trays can be regarded as the "lifeline carrier" of power and signal transmission. The quality of cable trays is not a small matter. The trouble caused by poor quality cable trays can lead to difficulties in engineering and even endanger the safety of life and property.

　　從項(xiàng)目施工階段說(shuō)起，選用劣質(zhì)電纜橋架，就如同埋下一顆 “定時(shí)炸彈”。一些廠家為壓縮成本，在板材厚度上偷工減料，標(biāo)稱 2 毫米厚的橋架，實(shí)際可能僅有 1.2 毫米甚更薄。如此一來(lái)，橋架的承重能力大打折扣，在安裝過(guò)程中，稍微受力就容易發(fā)生彎曲變形。想象一下，施工人員正有條不紊地敷設(shè)電纜，卻突然發(fā)現(xiàn)橋架因無(wú)法承受重量而扭曲，不僅安裝進(jìn)度被迫中斷，已敷設(shè)好的部分電纜也可能因橋架變形而受損，前期投入的人力、物力瞬間付諸東流，施工成本大幅增加，工期更是被無(wú)限拉長(zhǎng)。

　　Starting from the construction phase of the project, choosing low-quality cable trays is like planting a 'time bomb'. Some manufacturers cut corners on the thickness of the boards in order to reduce costs. A bridge with a nominal thickness of 2 millimeters may actually be only 1.2 millimeters or even thinner. In this way, the load-bearing capacity of the bridge is greatly reduced, and during installation, it is easy to bend and deform under slight stress. Imagine a construction worker laying cables in an orderly manner, only to suddenly discover that the cable tray is twisted due to the inability to bear weight. Not only is the installation progress forced to be interrupted, but the already laid cables may also be damaged due to the deformation of the cable tray. The manpower and material resources invested in the early stage are instantly diverted to the east, resulting in a significant increase in construction costs and an infinite extension of the construction period.

　　進(jìn)入使用階段，劣質(zhì)電纜橋架的弊端愈發(fā)凸顯。由于材質(zhì)不佳，其耐腐蝕性能極差。在普通室內(nèi)環(huán)境下，或許短時(shí)間內(nèi)還能勉強(qiáng)維持，但一旦處于潮濕的地下室、沿海高鹽霧地區(qū)，或是化工企業(yè)等有腐蝕性氣體的特殊環(huán)境中，幾個(gè)月時(shí)間，橋架便開(kāi)始生銹腐蝕。先是表面出現(xiàn)斑駁銹點(diǎn)，接著銹跡蔓延，鍍鋅層或涂層起泡、剝落，直橋架結(jié)構(gòu)被破壞。當(dāng)橋架被銹穿，失去對(duì)電纜的有效支撐與保護(hù)，電纜絕緣層暴露在外，極易因受潮、受腐蝕而損壞，引發(fā)漏電、短路等嚴(yán)重故障。

　　As we enter the usage stage, the drawbacks of inferior cable trays become increasingly prominent. Due to poor material quality, its corrosion resistance is extremely poor. In a normal indoor environment, it may be able to barely maintain for a short period of time, but once it is in a damp basement, high salt spray area along the sea, or a special environment with corrosive gases such as chemical enterprises, the bridge frame begins to rust and corrode after a few months. Firstly, there are mottled rust spots on the surface, followed by the spread of rust, blistering and peeling of the galvanized layer or coating, until the bridge structure is damaged. When the cable tray is corroded and loses effective support and protection for the cable, the insulation layer of the cable is exposed and easily damaged due to moisture and corrosion, causing serious faults such as leakage and short circuit.

　　這些故障所帶來(lái)的影響是的。對(duì)企業(yè)生產(chǎn)而言，一旦因電纜故障導(dǎo)致停電停產(chǎn)，每一分鐘的損失都難以估量。生產(chǎn)線停滯，設(shè)備空轉(zhuǎn)，訂單交付延遲，不僅要面臨客戶的巨額索賠，企業(yè)信譽(yù)也會(huì)遭受重創(chuàng)，多年積累的市場(chǎng)口碑毀于一旦。以一家電子制造企業(yè)為例，因車間內(nèi)劣質(zhì)電纜橋架引發(fā)短路停電，一次事故就造成了數(shù)十萬(wàn)元的直接經(jīng)濟(jì)損失，包括產(chǎn)品報(bào)廢、設(shè)備維修費(fèi)用等，間接損失如客戶流失、后續(xù)訂單減少等更是難以統(tǒng)計(jì)。

　　The impact of these faults is comprehensive. For enterprise production, once a power outage or shutdown is caused by cable failure, the loss of every minute is difficult to estimate. The production line stagnates, equipment runs idle, and order delivery is delayed. Not only will it face huge claims from customers, but the company's reputation will also be severely damaged, and years of accumulated market reputation will be destroyed. Taking an electronic manufacturing enterprise as an example, a short circuit and power outage caused by poor quality cable trays in the workshop resulted in direct economic losses of hundreds of thousands of yuan in one accident, including product scrapping, equipment maintenance costs, etc. Indirect losses such as customer loss and subsequent order reduction are difficult to calculate.

　　在人員方面，劣質(zhì)電纜橋架引發(fā)的電氣事故，可能對(duì)現(xiàn)場(chǎng)人員造成直接傷害。漏電事故發(fā)生時(shí)，周邊人員一旦接觸到帶電區(qū)域，便有觸電風(fēng)險(xiǎn)，危及生命；而短路引發(fā)的火災(zāi)，火勢(shì)蔓延迅速，在封閉空間內(nèi)，高溫濃煙還會(huì)造成人員窒息。在一些老舊建筑改造項(xiàng)目中，因使用了不符合標(biāo)準(zhǔn)的劣質(zhì)橋架，電氣火災(zāi)時(shí)有發(fā)生，給居民生命財(cái)產(chǎn)帶來(lái)極大威脅。

　　In terms of personnel safety, electrical accidents caused by poor quality cable trays may directly harm on-site personnel. When a leakage accident occurs, there is a risk of electric shock to surrounding personnel once they come into contact with the live area, which endangers their life safety; The fire caused by a short circuit spreads rapidly, and in enclosed spaces, high temperatures and thick smoke can cause suffocation of personnel. In some renovation projects of old buildings, electrical fires often occur due to the use of substandard and inferior cable trays, posing a great threat to the safety of residents' lives and property.
