Description

Technical Field

[0001] This utility model relates to a novel high-temperature abrasion resistance testing machine for cables, belonging to the field of wire and cable technology. Background Technology

[0002] In the wire and cable industry, with technological advancements and ever-increasing market demands, the performance requirements for cable products are becoming increasingly stringent. As a crucial medium for power transmission and communication, the abrasion resistance of cables directly impacts their service life and safety. Currently, cables are increasingly used in environments involving high temperatures, humidity, and mechanical abrasion; therefore, developing an effective abrasion resistance testing device is of paramount importance.

[0003] Currently, testing equipment for the abrasion resistance of wires and cables remains scarce in the market. Most existing testing methods cannot conduct systematic and accurate abrasion resistance assessments across a range from room temperature to high temperatures. This presents cable manufacturers with certain challenges in product quality control, especially after products leave the factory, making it difficult to effectively assess their abrasion resistance in practical applications.

[0004] To address this issue, the development of a dedicated abrasion resistance testing device is particularly urgent. This device can quantitatively measure the abrasion resistance of different types of cables before the outer layer is penetrated under fixed experimental conditions. This quantitative data can not only help manufacturers better understand and control the abrasion resistance of cables, but also provide a scientific basis for product improvement and upgrades.
