很多人使用電纜橋架施工以為僅僅了解它的安裝相關(guān)方面的問(wèn)題就行，其他的內(nèi)容不是很重要，這就大錯(cuò)特錯(cuò)了，多面了解才能更好使用不出問(wèn)題，下面來(lái)了解了解其他方面內(nèi)容吧，

Many people use cable tray construction to think that it is only necessary to understand the problems related to its installation. Other contents are not very important. This is a big mistake. Only by understanding from many aspects can we better use the cable tray without problems. Let's learn about other aspects,

電纜橋架由鋼制成，由直段、彎頭、附件、橋架支吊架、梯架等組成，是用于支撐電纜的連續(xù)剛性結(jié)構(gòu)體系的總稱。電纜橋架通過(guò)自身的結(jié)構(gòu)特性將電纜附著和支撐到建筑物（構(gòu)筑物）上，或獨(dú)立支撐電纜穿過(guò)隧道或洞穴、地下、空氣等，主要起到支撐電纜的作用。同時(shí)，由于電纜橋架將電纜與外界隔離，對(duì)電纜也有重要的保護(hù)作用，在很大程度上便于電纜的科學(xué)布置和管理。

The cable tray is made of steel and consists of straight sections, elbows, accessories, tray supports and hangers, ladders, etc. it is the general name of the continuous rigid structural system used to support cables. Cable trays attach and support cables to buildings (structures) through their own structural characteristics, or independently support cables through tunnels or caves, underground, air, etc., mainly to support cables. At the same time, because the cable tray isolates the cable from the outside world, it also plays an important role in protecting the cable, which is convenient for the scientific layout and management of the cable to a great extent.

鍍鋅后粉末或油漆的復(fù)合防腐處理

Composite anti-corrosion treatment of galvanized powder or paint

表面處理過(guò)的電纜橋架的技術(shù)質(zhì)量是否滿足產(chǎn)品工藝及相關(guān)可用性的要求，可以通過(guò)涂層厚度、表面鈍化、鋅層附著力、鋅層均勻性、外觀、沖擊強(qiáng)度、柔韌性和邊角等方面來(lái)確定。覆蓋率和其他檢測(cè)指標(biāo)。

Whether the technical quality of the surface treated cable tray meets the requirements of product process and related usability can be determined by the coating thickness, surface passivation, zinc layer adhesion, zinc layer uniformity, appearance, impact strength, flexibility, edges and corners, etc. Coverage and other indicators.

關(guān)于防腐層的環(huán)境試驗(yàn)，要嚴(yán)格區(qū)分不同類型的室內(nèi)外環(huán)境。交變濕熱、鹽霧試驗(yàn)和化學(xué)腐蝕性氣體試驗(yàn)按相應(yīng)的方法標(biāo)準(zhǔn)進(jìn)行。對(duì)于紫外線冷凝測(cè)試，與室內(nèi)相比，紫外線主要存在于室外環(huán)境中，因此光照條件和持續(xù)時(shí)間必須滿足相應(yīng)要求，避免測(cè)量數(shù)據(jù)與實(shí)際數(shù)據(jù)出現(xiàn)較大偏差。

As for the environmental test of anti-corrosion coating, it is necessary to strictly distinguish different types of indoor and outdoor environments. Alternating damp heat, salt spray test and chemical corrosive gas test shall be carried out according to corresponding method standards. For the UV condensation test, compared with indoor, UV mainly exists in the outdoor environment, so the lighting conditions and duration must meet the corresponding requirements to avoid large deviation between the measured data and the actual data.

測(cè)試時(shí)，應(yīng)根據(jù)具體的表面處理方法和使用要求選擇相應(yīng)的技術(shù)指標(biāo)，而不是每種類型都需要選擇上述所有指標(biāo)。

During the test, the corresponding technical indicators shall be selected according to the specific surface treatment methods and use requirements, instead of all the above indicators for each type.

同時(shí)，為滿足耐火要求，在進(jìn)行防護(hù)處理時(shí)還應(yīng)考慮耐火要求。如果防腐層不能滿足耐火和耐火要求，還應(yīng)通過(guò)涂裝耐火涂料進(jìn)行防火處理。

At the same time, in order to meet the fire resistance requirements, the fire resistance requirements shall also be considered during the protective treatment. If the anti-corrosion coating cannot meet the fire resistance and fire resistance requirements, it shall also be treated by coating fire-resistant coating.

根據(jù)其耐火極限時(shí)間要求的不同，相關(guān)技術(shù)規(guī)范將耐火橋的耐火極限分為三個(gè)等級(jí)：NH1、NH2和NH3。耐火性能試驗(yàn)應(yīng)按產(chǎn)品相關(guān)標(biāo)準(zhǔn)進(jìn)行，耐火橋表面的耐火涂層應(yīng)滿足涂層附著力、抗彎、抗沖擊、耐水、厚度等技術(shù)質(zhì)量要求和抗凍融性。

According to different requirements for fire endurance time, the fire endurance of fire-resistant bridges is divided into three grades in relevant technical specifications: nh1, NH2 and NH3. The fire resistance test shall be carried out according to relevant product standards. The fire-resistant coating on the surface of the fire-resistant bridge shall meet the technical quality requirements such as coating adhesion, bending resistance, impact resistance, water resistance, thickness and freeze-thaw resistance.

為了更真實(shí)地模擬實(shí)際使用場(chǎng)景，在進(jìn)行耐火電纜橋架的耐火等級(jí)測(cè)試時(shí)，不僅應(yīng)有少兩條直線段的耐火電纜橋架，而且應(yīng)有足夠多的連接器。符合實(shí)際使用條件，還必須符合測(cè)試要求。電纜的狀況。

In order to more truly simulate the actual use scenario, when testing the fire resistance rating of fire-resistant cable trays, there should be not only fire-resistant cable trays with at least two straight sections, but also enough connectors. Meet the actual use conditions and test requirements. Condition of cables.

立柱支架和耐火電纜橋架依次安裝在試驗(yàn)爐內(nèi)后，試驗(yàn)用電纜必須按相應(yīng)要求敷設(shè)在耐火電纜橋架內(nèi)，裝載時(shí)，裝載點(diǎn)應(yīng)避開(kāi)試驗(yàn)電纜。

After the column support and fire-resistant cable tray are installed in the test furnace in turn, the test cable must be laid in the fire-resistant cable tray according to the corresponding requirements. During loading, the loading point should avoid the test cable.

濟(jì)南電纜橋架廠家認(rèn)為不同材質(zhì)和結(jié)構(gòu)形式的電纜橋架功能不同，對(duì)電纜的保護(hù)也是多樣化的。在實(shí)際應(yīng)用中，應(yīng)因地制宜選擇合適的電纜橋架，并按照相關(guān)規(guī)范進(jìn)行檢驗(yàn)檢測(cè)，以確保產(chǎn)品質(zhì)量。規(guī)范建設(shè)，確保相關(guān)工程質(zhì)量。

Jinan cable tray manufacturers believe that cable trays of different materials and structural forms have different functions, and the protection of cables is also diversified. In practical application, appropriate cable trays shall be selected according to local conditions and inspected according to relevant specifications to ensure product quality. Standardize the construction and ensure the quality of relevant projects.
