Connectors are color coded for cable type. Strip cable to dimensions shown on chart. Remove cable jacket and dielectric 3. Fold exposed braid back over cable jacket leaving smooth foil attached to dielectric 4. For Quad Shield Cable: Fold outer braid back over jacket, remove outer foil and fold inner braid back over jacket. The stripper is required because the different bands in the coax cable have to be cut precisely to different lengths and depths, and this is difficult to do without the proper tool.
The BNC Crimper is used twice in the process - first to crimp the BNC pin to the main conductor, and then to crimp the collar over the outer insulation at the end of the operation. A quality crimper can make the difference between a connection that works and one that has to be discarded. It is also a good idea to make a length of test cable and try it out between a couple of computers on the system before actually going through the trouble of pulling cable through wall and ceiling spaces.
You don't want to do all that hard work only to find you've got the wrong cabling! The connector itself consists of three parts: the connector itself, the center pin, and the crimp barrel. Leave yourself a few extra feet of cable length for mistakes. If you get a bad connector, you'll be able to cut it off and try again.
Setting up the cable stripper may require some trial and error adjustment. You then rotate the stripper about the cable until the two layers of insulation and the shielding are cut through to their proper depths. If the cable stripper does not completely do its job, you may have to clean up the cable end with an X-acto knife or needle file. Care counts here. The center conductor should not be nicked, nor should any of the braided shielding be exposed - the most difficult part of this operation is to strip the shielding without damaging the inner insulation band.
The resulting length of exposed center conductor is the amount of conductor that will have to be cut off for a proper fit. Take the pin back off and cut the center conductor to the correct length with side cutter pliers.
Now when the pin is placed back on the conductor, its base should just reach the inner insulation band the center conductor should no longer be exposed. Place the pin on the center conductor, snug up the crimping tool over the pin in the special die portion of the crimper provided for the pin. Be careful. If this is messed up, you have to start over prepping the cable again with a new connector. Have a few more connectors on hand, even though you'll get good at this, mistakes are made, and if you don't have enough you'll put a real time strain on your project.
You will use them! Where drawing details dictate, laying of cables and spacing shall be maintained in trays as shown. Pulling of medium voltage cable in cable tray shall be performed by using conductor for pulling, not insulation or cable jacket. To properly facilitate pulling a sufficient amount of cable jacket, insulation and any other material shall be removed to expose the bare conductor. The installation of low voltage cable shall be performed using industry accepted methods and tools manufactured for the pulling of wire and cable.
Recorded data shall be made available for representative review. Cable manufacturer data shall be used in the design of the cable pulls. Maximum tension and sidewall pressure shall be considered in the rigging of the cable pull. Proper radius pulling wheels shall be used and adequately supported. Care must be taken when rigging supports from existing structures. If necessary temporary supports shall be installed for rigging of the pulling equipment. Care should also be taken to keep the tool well maintained, working properly and has an up to date calibration certificate.
More information can be found in our hydraulic tool maintenance guide. They should be tightly compacted to ensure maximum performance. The below image shows an under crimped lug left and an over crimped lug right.
Both these incorrectly crimped terminals can cause overheating and ultimately lead to termination failure or fire. The under crimped lug is identifiable by inspection of the lug and conductors.

The following steps provide simple instructions on how to crimp a cable lug to BS Once the crimp s have been performed, check the completed termination for: a No insulation is trapped in the barrel b Check the inspection hole to confirm the conductor has been fully inserted c Over-crimping — make sure the barrel is not over crimped causing excessive stress on the conductor and flash or burrs on the lug d Under crimping — No air voids should be found between the strands of the conductor.
