There are many types of cable trays to choose from, but tray type, trough type, ladder type, glass anti-corrosion flame retardant cable tray or steel ordinary type cable tray can be selected according to the site environment and technical requirements during use. Do you know when cable tray is used in electrical wiring? Next, Jinan cable tray manufacturer will explain to you.
Some are passive electrical (optical) cables (such as data cables, video coaxial cables, etc.). Therefore, when designing the wiring methods and routing arrangements, we should distinguish between them. They should not only meet the requirements of the specification, but also consider the safety, scalability, economy and beauty of the wiring for easy maintenance. As the carrier of various cable laying, the cable bridge, which is subordinate to the wiring needs, should also be implemented according to the above principles.
2. Use reason:
Due to the parallel crossing of multiple pipelines in the building and the limited space, especially in large office buildings, financial malls, hotels, venues and other buildings, the information points are dense. In addition to the use of floor trenches and embedded pipes in the wall, cable bridges are widely used in shafts and ceiling ceilings to provide wiring in different directions. Various cables of the weak current system are arranged in the bridge by category. The preferred route selection and installation method should be based on the requirements of the direction.
It shall be determined according to the negotiated position of the building structure, air conditioning, electrical and other pipelines. Passive cables cannot be laid side by side with active cables. They must be laid in the same bridge due to conditions. Metal partitions must be used between them. The outgoing cables should avoid plane crossing as far as possible. When the bridge passes through the floor, wall or expansion joint, the corresponding holes and positions should be marked on the building drawing to avoid temporary drilling due to omission, The civil structure may be damaged.
When is the bridge used in electrical wiring? The above is the answer to the question. If you have any questions or need to purchase cable tray, you can come to our website directly http://www.sddlqj.cn Get in touch!
