在電力傳輸與布線系統(tǒng)中，電纜橋架就像電纜的 “跑道”，承載著電纜的重量與電流的流動(dòng)。然而，當(dāng)這條 “跑道” 承重不達(dá)標(biāo)時(shí)，引發(fā)的連鎖反應(yīng)將對(duì)整個(gè)電力系統(tǒng)造成極大威脅。從設(shè)備損壞到隱患，每一個(gè)后果都不容小覷。

　　In power transmission and wiring systems, cable trays are like a "safe runway" for cables, carrying the weight of the cables and the flow of current. However, when the load-bearing capacity of this "runway" does not meet the standard, the chain reaction it triggers will pose a great threat to the entire power system. From equipment damage to safety hazards, every consequence should not be underestimated.

　　電纜橋架承重不達(dá)標(biāo)直接的影響，就是橋架本身發(fā)生變形甚斷裂。當(dāng)橋架承載的電纜重量超過其設(shè)計(jì)承重能力，橋架的橫梁、支架等部件會(huì)逐漸彎曲變形。初期可能只是輕微的下凹，肉眼難以察覺，但隨著時(shí)間推移，變形會(huì)愈發(fā)嚴(yán)重。終，橋架可能因無法承受重量而斷裂，導(dǎo)致其上的電纜墜落。這不僅會(huì)使電纜外層絕緣皮破損，內(nèi)部導(dǎo)體也可能受損，造成短路故障，致使電力供應(yīng)中斷。例如，在一些大型建筑的地下室或工業(yè)廠房中，電纜數(shù)量眾多且重量較大，若選用的橋架承重不足，就極易出現(xiàn)此類問題，影響整個(gè)區(qū)域的電力穩(wěn)定供應(yīng)。

　　The most direct impact of inadequate load-bearing capacity of cable trays is deformation or even fracture of the trays themselves. When the weight of the cables carried by the bridge exceeds its designed load-bearing capacity, the beams, brackets, and other components of the bridge will gradually bend and deform. At the beginning, it may only be a slight indentation that is difficult to detect with the naked eye, but over time, the deformation will become more severe. In the end, the bridge may break due to the inability to bear weight, causing the cables on it to fall. This not only damages the outer insulation layer of the cable, but also the internal conductor, causing a short circuit fault and resulting in power supply interruption. For example, in the basements or industrial plants of some large buildings, there are numerous and heavy cables. If the selected cable trays have insufficient load-bearing capacity, such problems are prone to occur, affecting the stable power supply of the entire area.

　　電纜橋架承重不足還會(huì)加速電纜的老化與損壞。正常情況下，電纜在橋架上應(yīng)處于平穩(wěn)、受力均勻的狀態(tài)。但當(dāng)橋架承重不達(dá)標(biāo)發(fā)生變形時(shí)，電纜會(huì)受到額外的拉扯、擠壓應(yīng)力。尤其是在橋架變形的彎曲部位，電纜局部受力過大，其絕緣層會(huì)因長期的機(jī)械應(yīng)力作用而出現(xiàn)龜裂、剝落現(xiàn)象。一旦絕緣層受損，電纜內(nèi)部的導(dǎo)體就會(huì)暴露在外，容易引發(fā)漏電、短路等電氣故障。而且，電纜的老化速度加快，原本設(shè)計(jì)使用壽命較長的電纜，可能因橋架承重問題而提前報(bào)廢，增加了后期的維護(hù)成本與更換難度。

　　Insufficient load-bearing capacity of cable trays can accelerate the aging and damage of cables. Under normal circumstances, cables on cable trays should be in a stable and evenly stressed state. But when the load-bearing capacity of the bridge is not up to standard and deformation occurs, the cable will be subjected to additional tensile and compressive stress. Especially in the curved areas where the bridge is deformed, if the cable is subjected to excessive local stress, the insulation layer may crack or peel off due to long-term mechanical stress. Once the insulation layer is damaged, the conductors inside the cable will be exposed, which can easily cause electrical faults such as leakage and short circuits. Moreover, the aging rate of cables accelerates, and cables that were originally designed to have a longer service life may be scrapped prematurely due to load-bearing issues with the bridge, increasing maintenance costs and difficulty in replacement in the later stages.

　　承重不達(dá)標(biāo)的電纜橋架，還會(huì)帶來嚴(yán)重的隱患。橋架斷裂或變形導(dǎo)致電纜墜落，不僅會(huì)破壞電力系統(tǒng)，還可能對(duì)周邊人員和設(shè)備造成傷害。在人員密集的場(chǎng)所，如、寫字樓，墜落的電纜可能砸傷行人；在工業(yè)生產(chǎn)區(qū)域，電纜墜落可能引發(fā)設(shè)備故障，甚導(dǎo)致生產(chǎn)線停機(jī)，造成重大經(jīng)濟(jì)損失。此外，電纜破損引發(fā)的漏電、短路，還有可能引發(fā)火災(zāi)事故。電纜短路瞬間產(chǎn)生的高溫，足以引燃周邊的易燃物，尤其是在一些存有易燃?xì)怏w、液體或粉塵的危險(xiǎn)環(huán)境中，火災(zāi)一旦發(fā)生，后果不堪設(shè)想，可能危及整個(gè)場(chǎng)所的。

　　Cable trays with inadequate load-bearing capacity can also pose serious safety hazards. Cable tray breakage or deformation leading to cable falling not only damages the power system, but may also cause harm to surrounding personnel and equipment. In densely populated areas such as shopping malls and office buildings, falling cables may injure pedestrians; In industrial production areas, cable falls may cause equipment failures and even lead to production line shutdowns, resulting in significant economic losses. In addition, leakage and short circuits caused by cable damage may also lead to fire accidents. The high temperature generated by a cable short circuit can ignite flammable materials in the surrounding area, especially in hazardous environments containing flammable gases, liquids, or dust. Once a fire occurs, the consequences are unimaginable and may endanger the safety of the entire site.

　　橋架承重不達(dá)標(biāo)還會(huì)干擾電力系統(tǒng)的正常運(yùn)行。當(dāng)電纜因橋架問題受損后，電力傳輸?shù)姆€(wěn)定性會(huì)受到影響。電壓波動(dòng)、電流不穩(wěn)等情況頻繁出現(xiàn)，會(huì)導(dǎo)致連接在該線路上的電氣設(shè)備無法正常工作。例如，一些對(duì)電力穩(wěn)定性要求極高的精密儀器、服務(wù)器等設(shè)備，在不穩(wěn)定的電力供應(yīng)下，可能出現(xiàn)數(shù)據(jù)丟失、設(shè)備損壞等問題，影響企業(yè)的正常生產(chǎn)經(jīng)營與數(shù)據(jù)。而且，頻繁的電力故障還會(huì)增加電力維護(hù)人員的工作負(fù)擔(dān)，降低整個(gè)電力系統(tǒng)的運(yùn)行效率。

　　The inadequate load-bearing capacity of the bridge frame can also interfere with the normal operation of the power system. When cables are damaged due to bridge problems, the stability of power transmission will be affected. Frequent voltage fluctuations, unstable currents, and other issues can cause electrical equipment connected to the circuit to malfunction. For example, some precision instruments, servers, and other equipment that require extremely high power stability may experience data loss, equipment damage, and other issues under unstable power supply, affecting the normal production and operation of enterprises and data security. Moreover, frequent power failures can increase the workload of power maintenance personnel and reduce the overall operational efficiency of the power system.
