The Rail Transit Car Wire Abrasion Testing Machine is designed to evaluate the abrasion resistance of wires used in rail transit vehicles. You can simulate real-world wear conditions on wire insulation and conductors to ensure compliance with rail industry standards and verify cable durability under operational stresses.

Application

This machine is suitable for testing:

(1) Rail transit vehicle cables with rated AC voltage of 3kV and below.

(2) Insulated and multi-core wires used in train carriages and rail electrical systems.

(3) Samples in R&D, quality control, and production verification of rail vehicle wiring.

Features

(1) Abrasion Monitoring – The machine automatically stops when the needle wears through the insulation and conductor contact occurs.

(2) U-Shaped Scraping Motion – Prevents one side of the sample from being scratched through prematurely.

(3) Adjustable Load – Supports 0.8–1.1 kg applied to the scraper for varying test intensities.

(4) Touch Screen Control – Allows precise setting of frequency, cycles, and count.

(5) Temperature Safety Monitoring – Ensures testing only occurs within defined ambient temperature ranges.

(6) High-Precision Transmission – Imported double slide rail mechanism ensures smooth, accurate needle movement.

(7) Sample Protection – Plexiglass cover maintains stable ambient conditions and prevents external interference.

Standards

(1) GB/T 12528-2008 – Standard for cables for rail transit vehicles with a rated AC voltage of 3kV and below
