The cable protection tube plays an important role in preventing short-circuit accidents caused by the disconnection of power lines. It protects cables, switches, and core boards, so that the whole machine is not burnt out, and it also has a certain isolation effect on the magnetic field interference of the power line.
Which places need to use cable protection tubes?
What are the laying requirements for cable protection pipes?
In building electrical engineering, the scope of use of cable protection pipes is as follows:
1. When the cable passes through the floor or wall of a building, tunnel, or when the cable is buried indoors, it is necessary to install a cable protection tube.
2. The cable is led from the channel to the pole and equipment, and a protective tube should be installed at a section of the cable below the height of 2m from the ground in a place that is easily accessible to pedestrians indoors.
3. A protective tube is required when the cable is laid under the road or when crossing the road:
4. For the cables drawn from the bridge, or where it is difficult to install the bridge and the cables are relatively scattered, a protective tube is set on the laid cable.
1. When the cable is parallel or crossed with the heating pipe, the cable should be protected by an asbestos cement pipe, and heat insulation measures should be taken.
2. When laying directly buried cables, you should bury the cable protection tube in advance, and wear it inside when the cable is laid to protect the cable tube from damage and facilitate replacement and inspection.
3. The depth of the protection pipe laid under the railway and highway should not be less than 1m. The length of the pipe should not only meet the width of the road surface but also extend 2m at both ends.
4. When the cable crosses the heating pipe, the extension length at both ends of the laying protection pipe should not be less than 2m.
5. When the cable protection pipe crosses other pipes (water, oil, gas pipes), the extension length at both ends should not be less than 1m.
6. The position of the cable pipe nozzle leading to the equipment should be convenient for the connection with the equipment, and does not hinder the disassembly, assembly, and access of the equipment.
7. The nozzles of the cable ducts laid side by side should be neatly arranged.
8. After the protective pipe is laid, the pipe openings at both ends should be blocked tightly to prevent foreign objects from affecting the cable laying.
Nowadays, the cable protection pipe has been well developed and gradually tends to unify international standards. Ease Industries & Investments Co., Ltd has developed a variety of different cable protection pipes and conducted a large number of tests before leaving the factory to ensure user experience. If you are in the cable protection pipe business, you can consider using our cost-effective products.
