Rail Transit Car Wire Abrasion Testing Machine
Category：Scratch Tester
Introduction
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.
Standards
(1) GB/T 12528-2008 – Standard for cables for rail transit vehicles with a rated AC voltage of 3kV and below

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.
Maintenance Information
(1) Keep the steel anvil, scraper, and needle clean and free of debris.
(2) Inspect the scraper and needle before each test for damage or wear.
(3) Ensure the slide rails are lubricated for smooth operation.
(4) Verify touch screen settings and calibration regularly.
(5) Maintain the plexiglass cover and control system to prevent ambient temperature fluctuations.
