Guiqiu brother and sister, even the villa to decorate, wire to re-wiring, I would like to ask you, wire threading tube that a wire root pipe (tube color is different, easy to identify), where to get ah The In addition, if there is no such thing, please recommend to me under the good threading tube, easy to repair, more durable
Wire tube is not a water pipe, can be any with three, four, P-shaped, S-shaped, U-shaped. Wire T connection, cross connector should have junction box. Grooved pipe connections are now widely used in building fire hydrant systems and sprinkler systems. In the design drawings are generally not marked out of the trench tee and mechanical tee. When the branch pipe is less than DN. and the main pipe diameter is greater than 2 times the diameter of the branch can be used mechanical three links (directly in the main channel hole), other circumstances have to use trench tee.
Cross-sectional area calculation formula: S = R? × π1-total area = 0.18 / 2 * 0.18 / 2 * .14 * 20 = . (mm2) 2-total area = .12 / 2 * .12 / 2 * .14 * 27 = 0 (square millimeters)
The ideal distance (I have read Telecom master how to pull) from the position of the patch panel to the fixed-line local machine folder behind the line, that is the best skin peel to that you have a bunch of twisted pair entered the cabinet that, If you are a patch panel, then stay up to 50 cm absolutely enough to see you stripping the skin is to facilitate the jumper when used with the time, you according to your actual situation that put a line in the patch panel are two answer it, you can find the right distance, then stay too redundant to do a 20-30 cm OK ======= ================================================== = Stripping the skin is not equal to the line is also spread, stripping is easy to use your jumper, because the thread is too short, when you jump when the line is very convenient, do not want to go beyond the distance on the root with something just around circle not to OK ?? you can put lines are straightened out, do not let inside the small copper wire or twisted together in the state, then with perimeter insulation or something do not let it spread like, in fact, in theory, will affect more than twisted away, in fact, you almost feel the impact of ~ ~ ~ Random points out, is not strictly required, then
