Understanding Cable Limits

As many in the wire and cable industry have found, it is imperative to use the correct cable for each application.  However, it can be difficult to understand all the different factors that play a role in a cable’s ability.  This is intended as a brief overview of four wire properties that can affect signal transmission.

  • The first is conductance.  Although other metal can be used, copper is by far the most common type of conductor.  Compared to other metals it has a lower hardness which helps its high electrical and thermal connectivity.
  • The second factor is shape.  Everything about the shape of a wire affects the conductivity from the size to twist and even the weave pattern.
  • The type of insulation is the third factor that affects the kind of cable required.  This prevents the signal from some decay by containing it within the conductor.  The most common types that are provided are PVC and Polyurethane, with the polyurethane being more flexible and durable.
  • The last major factor is shielding.  The purpose of shielding is to block out electromagnetic noise that can interfere with the signal.  Depending on the interference possible, cables can be shielded in different ways to optimize signal transmission.
