鋁合金電纜橋架安裝有什么要求?
鋁合金電纜橋架種類很多,不銹鋼,鋁合金,梯子,網(wǎng)等等,常見的。它們由支架、托架和安裝附件組成。橋架認(rèn)為橋架可以單獨使用,也可以連接各種工程建(構(gòu))筑物和水管支架。具有結(jié)構(gòu)簡單、設(shè)計美觀、設(shè)備靈活、維護(hù)方便等特點。
There are many kinds of aluminum alloy cable trays, such as stainless steel, aluminum alloy, ladder, net, etc. They consist of brackets, brackets and mounting accessories. It is considered that the bridge can be used alone or connected with various engineering buildings (structures) and water pipe supports. It has the characteristics of simple structure, beautiful design, flexible equipment and convenient maintenance.
1.在工程設(shè)計中,橋梁應(yīng)根據(jù)經(jīng)濟(jì)合理性、技術(shù)應(yīng)用可行性、運行穩(wěn)定性等因素綜合考慮,然后明確方案,這也需要滿足安裝、維護(hù)和電纜敷設(shè)的要求。
1. In the engineering design, the bridge shall be comprehensively considered according to the economic rationality, technical application feasibility, operation stability and other factors, and then the scheme shall be defined, which also needs to meet the requirements of installation, maintenance and cable laying.
2.水平敷設(shè)的橋架距路面的高度一般不小于2.5米,距路面1.8米以下的垂直橋架應(yīng)覆蓋防護(hù)金屬罩,專用于電氣設(shè)備的房間除外。鋁合金電纜橋架敷設(shè)在設(shè)備夾層或道路內(nèi)應(yīng)小于2.5m,并應(yīng)采取接地保護(hù)措施。
2. The height of the horizontally laid bridge from the road surface is generally not less than 2.5m, and the vertical bridge less than 1.8m from the road surface shall be covered with protective metal cover, except for the room dedicated to electrical equipment. The aluminum alloy cable tray shall be less than 2.5m laid in the equipment interlayer or road, and grounding protection measures shall be taken.
3.橋架、線槽及其支吊架在腐蝕性刺激性區(qū)域的環(huán)境中使用時。應(yīng)采用防腐處理,防腐處理應(yīng)滿足項目區(qū)域的環(huán)境和耐久性要求。適用于耐腐蝕規(guī)定或潔凈場所,應(yīng)選用鋁合金電纜橋架。
3. When the bridge, trunking and its supports and hangers are used in the environment of corrosive and irritating areas. Anti corrosion treatment shall be adopted, which shall meet the environmental and durability requirements of the project area. Aluminum alloy cable tray shall be selected for corrosion resistance regulations or clean places.
4.在防火規(guī)定范圍內(nèi),電纜梯架、橋架應(yīng)增加具有耐火或阻燃功能的板、網(wǎng)等材料,形成封閉或半封閉結(jié)構(gòu),并采取橋架、支架表面噴涂防火涂料等對策。整體耐火功能應(yīng)滿足相關(guān)法律、法規(guī)、規(guī)范或標(biāo)準(zhǔn)的要求。鋁合金電纜橋架不應(yīng)用于耐火要求高的場所。
4. Within the specified scope of fire prevention, the cable ladder and bridge shall be added with plates, nets and other materials with fire-resistant or flame-retardant function to form a closed or semi closed structure, and the countermeasures such as spraying fire-retardant coating on the surface of bridge and support shall be taken. The overall fire resistance function shall meet the requirements of relevant laws, regulations, specifications or standards. Aluminum alloy cable tray shall not be used in places with high fire resistance requirements.
5.對于需要屏蔽電纜線路的電磁干擾或室外陽光、油、腐蝕性刺激性液體和易燃粉塵等外部保護(hù)功能的區(qū)域環(huán)境的規(guī)定,不得使用孔鋁合金電纜橋架。
5. Perforated aluminum alloy cable trays shall not be used in areas requiring shielding electromagnetic interference of cable lines or external protection functions such as outdoor sunlight, oil, corrosive irritant liquid and flammable dust.
