电缆桥架的敷设
Laying of cable tray
电缆桥架可与工艺管线一起铺设,不单独占用电缆通道,节省空间,避免与地下管线交叉的问题。
The cable tray can be laid together with the process pipeline without occupying the cable channel separately, so as to save space and avoid the problem of crossing with underground pipelines.
电缆在空中敷设,散热条件比电缆隧道好,无需通风排水,运行成本低。扩建安装时,新增的电缆可以充分利用电缆桥架的空闲位置,用电非常方便。
When the cable is laid in the air, the heat dissipation condition is better than that of the cable tunnel. There is no need for ventilation and drainage, and the operation cost is low. During the expansion and installation, the new cables can make full use of the idle position of the cable tray, which is very convenient for power consumption.
与其他电缆铺设方式相比,电缆桥架具有明显的优势。无论厂区的主线还是某台设备内的布线,都可以采用电缆桥架的敷设方式。直埋电缆虽然成本低,但占地面积大。当安装扩大时,电缆需要重新开挖。
Compared with other cable laying methods, cable tray has obvious advantages. No matter the main line in the plant area or the wiring in a certain equipment, the laying method of cable tray can be adopted. Although the cost of directly buried cable is low, it covers a large area. When the installation is expanded, the cable needs to be re excavated.
电缆经常因扩建施工而损坏,导致停电,事故处理难度大,恢复供电时间较长,电缆直埋时,需要选择铠装电缆,比普通电缆贵,弯折不方便。
The cable is often damaged due to expansion construction, resulting in power failure. It is difficult to deal with the accident and takes a long time to restore power supply. When the cable is directly buried, it is necessary to select armored cable, which is more expensive than ordinary cable and inconvenient to bend.
桥架水平敷设时,其离地高度一般不小于2.5m垂直敷设时,离地1.8m以下的部分应有金属盖板保护,敷设在专用电气室内时除外。桥架应水平敷设在设备夹层内,或小于2.5m,并采取保护接地措施。
When the bridge is laid horizontally, its height above the ground is generally not less than 2.5m. When it is laid vertically, the part below 1.8m above the ground shall be protected by a metal cover plate, except when it is laid in a special electrical room. The bridge shall be horizontally laid in the equipment interlayer, or less than 2.5m, and protective grounding measures shall be taken.
电缆桥架的敷设布置

在工程设计中,桥架的布置应根据经济合理性、技术可行性、运营安全性等因素进行综合比较。确定一个好的方案,充分满足施工、安装、维护和电缆敷设的要求。
In the engineering design, the layout of the bridge shall be comprehensively compared according to the economic rationality, technical feasibility, operation safety and other factors. Determine a good scheme to fully meet the requirements of construction, installation, maintenance and cable laying.
当在腐蚀环境中使用时,桥架、线槽、支吊架应采用耐腐蚀的刚性材料。或采用防腐处理,防腐处理方法应满足工程、环境和耐久性的要求。对于耐腐蚀或洁净度要求高的场所,应选用铝合金电缆桥架。
When used in corrosive environment, the tray, trunking, supports and hangers shall be made of corrosion-resistant rigid materials. Or adopt anti-corrosion treatment. The anti-corrosion treatment method shall meet the requirements of the project, environment and durability. For places with high requirements for corrosion resistance or cleanliness, aluminum alloy cable trays shall be selected.
在有防火要求的地区,山东电缆桥架、电缆槽可加防火或阻燃板、网等材料,形成封闭或半封闭结构。
In areas with fire protection requirements, Shandong cable tray and cable trough can be added with fire-proof or flame-retardant plates, nets and other materials to form a closed or semi closed structure.
山东电缆桥架及其支吊架表面喷涂防火涂料等措施。其整体耐火性能应满足相关规范或标准的要求。铝合金电缆桥架不应用于防火要求高的场所。
The surface of Shandong cable tray and its supports and hangers shall be sprayed with fireproof paint and other measures. The overall fire resistance performance shall meet the requirements of relevant national codes or standards. Aluminum alloy cable trays shall not be used in places with high fire protection requirements.
此外随着火灾报警系列产品的改进,电缆探测器可用于对电缆进行监控。一旦某处温度过高,超过探测器设定值,可及时报警,以便值班人员及时巡查,消除隐患,以防意外。更多关于电缆桥架产品的事情您可以关注网站

In addition, with the improvement of fire alarm products, cable detectors can be used to monitor cables. Once the temperature at a certain place is too high and exceeds the set value of the detector, the alarm can be sent in time, so that the personnel on duty can patrol in time to eliminate hidden dangers and prevent accidents.
