Mechanical Requirements for Specifying Wire and Cable

Posted on Wednesday, January 27, 2016 by Paige DiAntonio

Last up in our long list of requirements and standards for specifying wire and cable are the mechanical requirements.  A mechanical property is defined as a characteristic that indicates certain behaviors of a material when a specific force is applied.  In a nut shell - what happens to material X when force Y is applied to it?  If a cable (material X) can withstand large amounts of surface wear (force Y), then it has the mechanical property of abrasion resistance.  Here is a list of the most common mechanical requirements in the wire & cable industry:

  • Abrasion Resistance: the ability of the material to resist surface wear

  • Cut-Through Resistance: the ability of the material to withstand mechanical pressure without separation

  • Elongation: The increase in length as the material is placed under tension

  • Flexibility: The quality of the cable that allows for bending under normal conditions

  • Flex Life: The ability of the cable to withstand repeated flexing without damage

  • Tensile Strength: The pulling strength required to break a given material

It is not always easy to determine whether the product you are viewing meets the mechanical property requirements you need.  Our Cable and Wire Finder can help you filter through various mechanical properties, assuring that you find the product that works best for your application.
