An abrasion machine is a laboratory testing device used to evaluate the abrasion resistance of wire and cable jackets by simulating repeated contact with abrasive surfaces.
Abrasion machines are essential in verifying the mechanical durability of wire and cable constructions, especially in environments where surface wear is a concern. These machines subject sample cable jackets to controlled wear conditions to measure how well they can withstand scraping, rubbing, or contact with rough materials.
The results provide manufacturers and specifiers with objective data to compare jacket compounds and select cables suited for demanding commercial or industrial conditions. High abrasion resistance is critical for cables used in high-traffic areas, around machinery, or in bundled systems where friction can degrade performance over time.
There are two standard types of abrasion testing machines commonly used in the wire and cable industry. The squirrel cage type features square steel bars that rotate to create repeated impact and friction on the cable’s surface. The abrasive grit type uses a rotating drum or belt with a gritty surface that simulates rubbing or scraping conditions more common in industrial installations. Each type offers a distinct method for evaluating jacket integrity and helps determine the longevity and toughness of a cable's outer layer under mechanical stress.
