Cable Abrasion Resistance Tester for Quality Control and R&D

Wires and cables are essential carriers for electrical power transmission and signal communication. As performance requirements continue to increase, the scrape abrasion resistance of cable insulation and sheath materials has become a critical factor in evaluating product durability and safety.

The Wire and Cable Scrape Abrasion Tester is a specialized instrument designed to assess the resistance of cable surfaces to scraping, cutting, and abrasion damage. By simulating real operational environments, it provides accurate, quantifiable data for quality control, R&D, and certification testing. This instrument is widely used in cable manufacturing plants, testing laboratories, research institutes, and inspection bodies.

Working Principle

The working principle of the Wire and Cable Scrape Abrasion Tester is based on mechanical loading and tribology (friction and wear) theory.

During testing:

A scraping head or abrasive device applies a controlled force to the cable surface.

The test system moves the scraper at a defined speed and frequency, simulating real-life friction, scraping, and wear conditions.

Sensors continuously collect key parameters such as:

Scraping force

Scraping speed

Number of scrape cycles

Wear depth or surface damage

The collected data is analyzed by the control system to calculate:

Abrasion index

Scrape resistance level

Wear performance evaluation

This ensures a precise, repeatable assessment of the cable’s surface durability under mechanical stress.
