What is the role of wire and cable protection hose and its specifications for use and installation specifications?
Author:
The function of the wire and cable protection hose is to protect the wire and cable in general, to avoid damage to the wire and cable, to prevent the damage of the cable and to prevent the leakage of electricity from causing serious harm to people and the environment. A certain understanding of how to use the specification is required.
How to use the wire protection tube Insert the wire and cable into the tube, and use it with the corresponding specification and model of the hose connector. The use method of the cable protection sleeve is that the threading tube has excellent insulation, because the threading tube is often used in power engineering, so The insulation performance of the threading pipe products is very important, so as to ensure the normal transmission of electricity. It can also avoid shrinkage and deformation, and the shape of the product will not change due to seasonal changes, which also makes the threading pipe maintain a long service life.
The installation specifications for wire and cable protection hoses are:
1. Metal steel pipes, non-metallic plastic pipes, ceramic pipes, asbestos cement pipes or concrete pipes and new composite fibers can be used for the construction of cable protection pipes, but the pipes are unimpeded.
2. Arrange the pipes into the desired shape according to the required number of holes, the pipe joints must be offset from each other, and the cement is used to pour the pipes as a whole, usually divided into 2, 4, 6, 8, 10, 12, 14, 16 holes, and so on;
3. The opening diameter of the cable sheath should generally not be less than 1.5 times the outer diameter of the cable, the opening diameter of the power line conduit should not be less than 100mm, and the opening diameter of the control cable should not be less than 75mm;
4. The distance between the top of the underground drainage pipe and the ground should be less than 50000mm on the sidewalk; - similar areas should not be less than 700mm;
5. Install drainage pipes at linear distances, corners and branches over 100 meters. Drainage pipes should have a slope of not less than 0.1% to direct water into the structure.
6. The cables inside the exhaust pipe must be shielded cables.
