在选择电缆桥架时应该满足哪些条件?

电缆桥架作为一种智能化弱电系统,在我们的日常生活中扮演着重要的角色。它弥补了一般电缆易下垂、易损坏等相关情况,对电缆、光纤起到良好的受托、保护、管理及后期维护作用。那么在选择济南电缆桥架时应该满足哪些条件呢?
As an intelligent weak current system, cable tray plays an important role in our daily life. It makes up for general cable sagging, damage and other related situations, and plays a good role in commissioning, protection, management and later maintenance of cables and optical fibers. What conditions should be met when selecting Jinan cable tray?
1、铺设距离。当桥架水平敷设时,离地面的高度至少不应低于2或5米。如果垂直敷设,应在离地面1或8米以下的位置安装金属盖板进行保护。但如果桥架敷设在专门的电气室内,则不需要安装保护盖板。另外,如果电缆桥架需要水平敷设在人路或设备夹层内,且仍在2.5米以下,应采取一定的接地保护措施。
1. Laying distance. When the bridge is laid horizontally, the height from the ground shall not be less than 2 or 5 meters. If it is laid vertically, a metal cover plate shall be installed 1 or 8 meters below the ground for protection. However, if the cable tray is laid in a special electrical room, it is not necessary to install a protective cover plate. In addition, if the cable tray needs to be laid horizontally in the sidewalk or equipment interlayer and is still below 2.5 meters, certain grounding protection measures should be taken.
2、使用无孔塔盘桥架。如果需要使用可以避免电磁干扰的保护桥,一定要选择无孔的托盘。
2. Use non perforated tray bridge. If you need to use a protective bridge that can avoid electromagnetic interference, you must choose a tray without holes.
3、应用于有防火要求的场所。如果桥架需要在防火要求的范围内,那么可以在桥架、电缆梯内放置一些用具有阻燃或防火性能的网等材料制成的半封闭或封闭的东西,也需要在桥架、支吊架表面刷一层防火涂料。否则,桥梁的整体耐火性能无法满足国家相关标准和规范的要求。而且在一些防火要求非常高的地方,还是尽量不要用铝合金电缆桥架。
3. It shall be used in places with fire protection requirements. If the bridge is required to be within the scope of fire protection requirements, then some semi enclosed or enclosed objects made of flame retardant or fire-resistant nets and other materials can be placed in the bridge and cable ladder, and a layer of fire-retardant coating is also required on the surface of the bridge, supports and hangers. Otherwise, the overall fire resistance of the bridge cannot meet the requirements of relevant national standards and specifications. In addition, aluminum alloy cable tray shall not be used in places with high fire protection requirements.
4、满足基本要素。在布置桥梁时,我们须根据运营经济合理性和技术可行性两个基本因素进行综合比较。否则,无法确定比较好的方案。同时要充分满足电缆敷设、施工安装、维护方便的要求。
4. Meet the basic elements. When arranging the bridge, we must make a comprehensive comparison based on the two basic factors of operational economic rationality and technical feasibility. Otherwise, it is impossible to determine a better plan. At the same time, it shall fully meet the requirements of cable laying, construction and installation, and convenient maintenance.
5、耐蚀性。如果线槽、桥架及支吊架在腐蚀环境中使用,应该使用经过防腐处理或采用耐腐蚀刚性材料制成的桥架,且耐腐蚀性能须达到标准。建议选择铝合金材质的桥架,耐腐蚀性更好。
5. Corrosion resistance. If trunking, cable tray and supports and hangers are used in a corrosive environment, they should be made of anti-corrosion treatment or corrosion resistant rigid materials, and the corrosion resistance must meet the standard. It is recommended to select aluminum alloy cable tray for better corrosion resistance.
以上五点就是选择济南电缆桥架应该满足的条件,对于其防火要求也很高,希望今天介绍的这些内容能对你有所帮助。
The above five points are the conditions that should be met when selecting cable bridges in Jinan. They also have high requirements for fire protection. I hope these contents introduced today can help you.
