Locomotive wire dynamic cutting through tester
Category：Other
Introduction
The Locomotive Wire Dynamic Cutting-Through Tester is a precision instrument designed to assess the mechanical strength and insulation integrity of locomotive and heavy-duty wires under dynamic cutting conditions. It simulates real-world mechanical stress by applying a controlled vertical force to the wire insulation until it is cut through, measuring the minimum cutting force required.
This tester is widely used in railway, metro, and electric vehicle wire production, as well as in quality control and research laboratories for verifying wire insulation durability and compliance with industry standards.
Applicable Standards
EN 50305 – Railway Applications: Test Methods for Electrical Wires
EN 50306:2002 – Railway Applications: Mechanical Tests for Wire Insulation
Compliance with these standards ensures that wires meet mechanical durability and safety requirements in rail and transportation applications.

R&D departments: Tests new insulation materials for mechanical performance under standardized conditions.
FAQ
1. What types of wires can be tested?
This tester is suitable for locomotive, metro, and heavy-duty electrical wires, including copper and copper alloy conductors with various insulation materials such as PVC, PE, XLPE, or specialized flame-retardant coatings.
2. How does the dynamic cutting test work?
The sample is fixed on a steel platform, and a 0.45 mm steel rod indenter is applied vertically across the wire. The machine applies a controlled downward force at an adjustable acceleration rate until the wire is cut through, and the minimum cutting force is recorded automatically.
3. How is the test monitored and displayed?
The instrument features an LCD digital display or optional computer software interface, showing force in real time. Units can be switched between N, kg, and lb. The software can also generate automated test reports for documentation.
4. Can the tester handle multiple samples at once?
Yes, the machine is designed to test up to 4 wire samples simultaneously, improving efficiency in quality control and production testing.
5. What safety features are included?
The tester automatically maintains the cutting force and stops the test once the sample is cut through, preventing damage to the equipment and ensuring operator safety.
