Cable to Cable Abrasion

This test is used to determine the ability of a sample’s insulation to withstand the rubbing on a similar sample in a vibrational environment. Wires/cables in close contact with one another can rub against each other causing progressive deterioration of the insulation. The impact of how quickly the insulation degrades in a wire-to-wire scenario is dependent on the inherent insulation properties as well as the particular construction. In this cable-to-cable abrasion test, the samples are rubbed together until electrical conductivity is detected between conductors (or shields) of the two test samples.

Smooth surface wire/cable insulation types tend to have a greater longevity in this test when compared to tape wrapped constructions. The uneven surface of tape wrapped constructions creates an abrasion point that accelerates the material wear.

There are several parameters that can be adjusted to the client's particular needs, including:

• Weight on Sample
• Abrasion Frequency
• Temperature
