About Hidden Cable Cabling, You Must Know the Hidden Rules

2. Cable laying requirements:

1.Before the cable is laid, check whether the specifications, routes, and locations conform to the design rules.

2. The laying of the cable should be straight, do not produce a circle and so on, do not have damage.

3.Before laying out the cable, there must be marks on both ends of the cable, indicating the start and end positions. The label should be used as far as possible.

4.Signal cables, power cables, twisted-pair cables, and other weak cables should be placed as far apart as possible.

The cabling should be redundant. In the secondary exchange room and between the equipment twisted pairs, 3-6 meters must be reserved and the working area should be 0.3-0.6 meters.

5.When laying cables, the distance between the fulcrums of the cables hanging during the traction should not exceed 1.5 meters.

3. Take the line:

Pull the cable from the cable box

a: Remove the plastic plug

b: Pull a few meters of cable through the outlet hole.

c: Pull out the required length of cable, cut it, slide the cable back into the slot, leaving 5 cm outside.

4. cable processing:

a. Use a diagonal pliers to open the “1” pattern outside the plastic.

b.Hold the cable firmly in one hand. Use a long nose pliers to hold one end of the nylon pull string and pull it away from the end of the cable. The length is determined as required.

c.Cut off the useless leather jacket.

5. cable traction:

1.When pulling multiple pairs of twisted pairs, bundle multiple cables into one bundle and let them terminate.

2.Use an electrician to glue tightly around the cable and wind 5-6 meters outside the end.

3.Pull the rope through the electrical cable with a good cable and knot it.

Note: If you loosen the connection point while pulling the cable, you must retract the cable, and then make a firm connection.

Horizontal wiring considerations:

1) Pipeline routing

Pipeline routing is when the concrete has been buried in the pipeline, the pipeline traction cable wire or wire, construction time to understand the pipeline map, make a construction plan.
If there is no embedded pipe, it should be done synchronously with the decoration, so that it is easy to wire and look beautiful and prevent rework.

2) In ceiling wiring:

a. Obtain a construction plan and determine the route.
B. Along the design route, open the ceiling and slowly push the panels apart with both hands.
c.Put multiple cable boxes side by side with the line up.
d. From the end furthest from the wiring closet, draw the end of the cable along the cable tray over the ceiling of the ceiling corridor.
e.Move the ladder to the next hole in the suspended ceiling until the rope reaches the end of the corridor.
