            桥架一般主要是在建筑室内及高压电的配电工程进行使用的,可以应用于不同的环境。桥架产品的安置要点关乎安全要重视,所以下面来看看要点内容有什么。
            The bridge is generally used in indoor buildings and high-voltage power distribution projects, which can be applied to different environments. The key points of bridge product placement are related to safety and should be paid attention to, so let's see what the key points are.
            1、在有防火要求的路段,索梯和桥架可加装耐火或阻燃板、网等材料,形成封闭或半封闭结构,桥架及其支吊架可以使用。表面涂有防火涂料等措施。
            1. In the sections with fire prevention requirements, the cable ladder and bridge can be equipped with fire-resistant or flame-retardant plates, nets and other materials to form a closed or semi closed structure. The bridge and its supports and hangers can be used. The surface is coated with fireproof coating and other measures.
            2、钢索桥架直线段长度超过30m,铝合金桥架超过15m,或桥梁通过建筑物伸缩(沉降)缝时,应预留0-30mm的补偿余量,连接宜采用伸缩连接板。
            2. When the straight section length of steel cable bridge exceeds 30m, aluminum alloy bridge exceeds 15m, or the bridge passes through the expansion (settlement) joint of the building, a compensation allowance of 0-30mm shall be reserved, and the expansion connecting plate should be used for connection.
            3、在工程设计中,桥架布置应根据经济合理性、技术可行性、运行安全等因素综合比较,确定方案,充分满足施工、安装、维修的要求,和电缆铺设。
            3. In the engineering design, the bridge layout shall be determined according to the comprehensive comparison of economic rationality, technical feasibility, operation safety and other factors, so as to fully meet the requirements of construction, installation and maintenance and cable laying.
            4、在腐蚀性环境中使用时,山东电缆桥架、线槽及其支吊架应采用耐腐蚀的刚性材料,或进行防腐处理。防腐处理方法应符合工程环境和耐久性要求。对于耐腐蚀或清洁度要求较高的场所,应选用铝合金电缆桥架。
            4. When used in corrosive environment, Shandong cable tray, trunking and its supports and hangers shall be made of corrosion-resistant rigid materials or subject to anti-corrosion treatment. The anti-corrosion treatment method shall meet the requirements of engineering environment and durability. For places with high corrosion resistance or cleanliness requirements, aluminum alloy cable tray shall be selected.、

            5、山东桥架的宽度和高度的选择应满足填充率的要求。一般来说,梯架和托盘中的电缆填充率应为电力电缆的40-50%,控制电缆的50-50%。70,10-25%应预留给项目开发。
            5. The width and height of Shandong bridge shall meet the requirements of filling rate. In general, the cable filling rate in ladders and trays shall be 40-50% of power cables and 50-50% of control cables. 70,10-25% should be reserved for project development.
            6、需要屏蔽电磁干扰的电缆线路。或者当有环境要求以防止外部影响时,例如室外阳光、油、腐蚀性液体和易燃粉尘。应选择无孔桥架式电缆桥架。
            6. Cable lines that need to be shielded from electromagnetic interference. Or when there are environmental requirements to prevent external effects, such as outdoor sunlight, oil, corrosive liquids and flammable dust. Non perforated bridge type cable tray shall be selected.
            7、要求电缆的厚度至少与板厚相同或低一级。还应对电缆桥架的外观和形状进行检修,以确保电缆桥架平整、清洁、无损坏。桥的厚度也要用专业的检测仪器检查,桥的表面光泽度不得低于规定的60%。此外,表面还应有防雾保护层等。
            7. The thickness of the cable is required to be at least the same as or one level lower than the plate thickness. The appearance and shape of the cable tray shall also be overhauled to ensure that the cable tray is flat, clean and free from damage. The thickness of the bridge shall not be less than 60% of the specified surface gloss. In addition, the surface shall also have anti fog protective layer, etc.
            8、在容易积尘的地方,应用盖板盖住桥架;在公共通道或室外过马路段,应在底桥上加垫板或无孔托盘。
            8. Cover the bridge with cover plate in the place where dust is easy to accumulate; In the public passage or outdoor road crossing section, the base plate or non perforated tray shall be added on the bottom bridge.
            以上就是山东桥架的安置需要考虑到的一些要点,在使用电缆桥架时要格外注意细节,这样才能有利于桥架的后期使用,更多信息的获取就来网站www.drcrawfordndms.com关注吧。
            The above are some key points to be considered in the placement of cable trays in Shandong. Pay special attention to details when using cable trays, so as to facilitate the later use of cable trays. For more information, please visit www.sddlqj.com Cn pay attention.
