槽式電纜橋架寬度和高度填充說(shuō)明
電纜橋架廠家技能在不斷的革新,企業(yè)也加強(qiáng)了對(duì)電纜橋架質(zhì)量的管理,從而進(jìn)一步完善了它的生產(chǎn)工藝,為行業(yè)開展帶來(lái)了有利的條件,也給電纜施工和電纜裝置帶來(lái)了便利與好處。
The skills of cable tray manufacturers are constantly innovating, and enterprises have also strengthened their management of cable tray quality, further improving their production processes, bringing favorable conditions for industry development, and also bringing convenience and benefits to cable construction and cable installation.
電纜橋架的分類:梯級(jí)式線纜橋架、托盤式線纜橋架梯級(jí)式線纜橋架Q1-T型梯級(jí)式電纜橋架是依據(jù)國(guó)內(nèi)外有關(guān)資料而改進(jìn)設(shè)計(jì)的。它具有重量輕、成本低、造型別具、裝置便利、散熱、透氣好等長(zhǎng)處。適用于一般直徑較大電纜的敷設(shè),適合于高、低壓動(dòng)力電纜的敷設(shè)。托盤式線纜橋架托盤式電纜橋架是石油、化工、輕工、電訊等方面使用廣泛的一種。它具有重量輕、載荷大、造型漂亮、結(jié)構(gòu)簡(jiǎn)單、裝置便利等長(zhǎng)處。它即適用于動(dòng)力電纜的裝置,也適合于操控電纜的敷設(shè)。
The classification of cable trays: stepped cable trays, tray type cable trays. The Q1-T type stepped cable trays have been improved and designed based on relevant domestic and foreign data. It has advantages such as light weight, low cost, unique design, convenient installation, good heat dissipation, and breathability. Suitable for laying cables with larger diameters and for laying high and low voltage power cables. Tray type cable tray tray is a widely used type in petroleum, chemical, light industry, telecommunications, and other fields. It has advantages such as light weight, large load, beautiful design, simple structure, and convenient installation. It is suitable for both the installation of power cables and the laying of control cables.
橋架的裝置:橫平豎直,彎頭處要陡峭。當(dāng)橋架分層時(shí),好用組合架。橋架內(nèi)部要加設(shè)防火封堵或加設(shè)防火包。鋼制30米,鋁合金及塑料的15米要加伸縮節(jié)。過(guò)建筑物變形縫處(伸縮縫、沉降縫)加補(bǔ)償裝置。橋架的支架間距一般要求水平的為1.5-3米,垂直的為2米一個(gè)。螺母坐落橋架的外側(cè)。當(dāng)支架與鋁合金橋架連接時(shí),留意防電化辦法。留意轉(zhuǎn)彎處支架的設(shè)置。配電室大型橋架要采用可調(diào)式組合支架 大型工程橋架彎曲度要共同。
The installation of the bridge should be horizontal and vertical, with steep bends. When the bridge is layered, it is easy to use a combination frame. Fire blocking or fire protection packages should be installed inside the bridge. Steel 30 meters, aluminum alloy and plastic 15 meters require expansion joints. Compensation devices shall be added at deformation joints (Expansion joint and settlement joints) passing through buildings. The spacing between the supports of the bridge is generally required to be 1.5 to 3 meters horizontally and 2 meters vertically. The nut is located on the outer side of the bridge. When connecting the bracket to the aluminum alloy bridge, pay attention to anti electrochemical methods. Pay attention to the setting of brackets at turns. The large cable tray in the power distribution room should use adjustable combination supports, and the bending degree of the large engineering cable tray should be common.
電纜橋架在有防火要求的區(qū)段內(nèi),可在電纜梯架、托盤內(nèi)增加具有耐火或難燃功能的板、網(wǎng)等資料構(gòu)成封閉或半封閉式結(jié)構(gòu),并采納在橋架及其支吊架外表涂刷防火涂層等辦法,其整體耐火功能應(yīng)滿足有關(guān)規(guī)范或規(guī)范的要求。在工程防火要求較高的場(chǎng)所,不宜采用鋁合金電纜橋架。
In sections with fire protection requirements, cable trays can be equipped with fire-resistant or flame-retardant boards, nets, and other materials to form a closed or semi closed structure. Measures such as applying fire-resistant coatings on the surface of the cable tray and its supports and hangers should be adopted, and its overall fire resistance function should meet the requirements of relevant national regulations or specifications. Aluminum alloy cable trays should not be used in places with high fire protection requirements in engineering.
槽式電纜橋架寬度和高度的挑選應(yīng)符合填充率的要求,電纜的梯架和托盤內(nèi)的填充率在一般情況下,電力電纜可取40~50,操控電纜可取50~70,且宜預(yù)留10~25工程開展裕量。在挑選電纜橋架的荷載等級(jí)時(shí),電纜橋架的工作均布荷載不應(yīng)大于所選電纜橋架荷載等級(jí)的額外均布荷載,如果電纜橋架的支吊架的實(shí)際跨距不等于2m 時(shí),則工作均布荷載應(yīng)滿足要求。
The selection of the width and height of the trough type cable tray should meet the requirements of filling rate. In general, the filling rate in the cable ladder and tray can be 40-50 for power cables and 50-70 for control cables, and a margin of 10-25 should be reserved for engineering development. When selecting the load level of the cable tray, the working uniform load of the cable tray should not exceed the additional uniform load of the selected cable tray load level. If the actual span of the support and hanger of the cable tray is not equal to 2 meters, the working uniform load should meet the requirements.
