Question:

Construction electrical engineering wire conduit, cable duct and trunking should be carried out according to what procedures?

Ready to wear cable TV coaxial cable, see a kind of threading on the Internet, do not know how to use. Listen to someone say there is a kind of head with a wheel, do not know someone used it? Question added: the original tube is from the weak to the unified management of the house, there should be a lot of turning, wire is not estimated. And upstairs downstairs to re-wiring is also too exaggerated, at least 200m, how much waste of the tube ah, the destruction of the original structure is not good. Has tried the wire, does not work. It seems no one used the threader, the problem is closed. More

Answer:

The following conditions should be cable protection . the cable into the building, through the floor and the wall. . from the cable channel lead to the poles, wall surface and the house pedestrian easy access to the cable, from the ground height of 2m below a section. . other places may be subject to mechanical damage, the depth of the protection tube buried in the ground should not be less than 100mm, out of the building, the length of the water should not be less than 250mm. The cable tube diameter should not be less than 1.5 times the cable diameter.
1) the impact is certainly some; 2) standard case, the telephone line, the network line can be the same tube; 3) TV line independent 4) power is to be independent;
Will affect the broadband speed, will also increase the noise to the phone. May not be any problems for the time being.
