Identifying Your Requirements

Rack[1]

Selecting cable that’s best for purpose:

From a project management perspective, there are four core criteria for cable selection:

  • Ease of termination: Speed and convenience for wiring technicians
  • Electrical performance: Minimum insertion loss and best phase linearity
  • Ease of handling: Flexibility, ruggedness and longevity
  • Price: Not just per-metre prices but the installed and commissioned price

However, often the choice of cable is not made at project management level.
A “first-fit” contractor is only interested in ease of handling and speed of deployment. A wiring technician’s selection will be based on ease of termination and not a care for the system performance. The system engineer will be interested in electrical performance and who gives a damn how difficult it is to terminate? All parties are interested in price only if they are paying!

 

rigger[1]The prevailing criteria to select cable should depend on the project. Bear in mind that selection can have a very significant impact on overall installed cost and performance.
