Unit 5. Assignment 1.Cabling Factors and Tools Discussion
Some factors to keep in mind when installing cable:
Always use more cable than you need. Leave plenty of slack.
Test every part of a network as you install it. Even if it is brand new, it may have problems that will be difficult to isolate later.
Stay at least 3 feet away from fluorescent light boxes and other sources of electrical interference.
If it is necessary to run cable across the floor, cover the cable with cable protectors.
Label both ends of each cable.
Use cable ties (not tape) to keep cables in the same location together.
Some aspects of proper design are:
Pulling Tension, many cables are pulled into position. When pulling a cable, it is critical to first attach the pulling line in the correct manner; second avoid exceeding the maximum tensile strength of the cable, and last relieve the pulling tension once the cables are in place.
What tools would be useful?
Cable Installation Poles
Electrical Tapes
Fish Tapes & Cable Pulling
Heat Guns & Shrink Tubing
Nylon & Velcro Cable Ties
Safety Climbing Gear
Wire and Cable Holders
Work Tents and Umbrellas
What would be an example of a makeshift tool? Tennis Ball – tie a tennis ball using duct tape, nails, screws and throw the ball from the source to destination. The other end of the pull string can be tied to the bundle of cables so that it can be pulled from source to destination without you going up and down the ladder too many times.
Fish Tape - A roll of spring steel or fiberglass with a hook on the end. A bunch of cable can be hooked and pulled through a small area, or the cables can be taped to the fish tape and pushed through the conduit or wall cavity.
