FAQ
1. What type of wires can be tested?
This tester is suitable for fluoropolymer-insulated wires, commonly used in aerospace and high-reliability industrial applications. It can handle wires with various diameters, as long as the test indenter and clamps are compatible.
2. How does the dynamic cutting test work?
The wire sample is fixed on a steel platform. A 0.51 mm steel rod indenter applies a controlled vertical force at 5 mm/min until the wire is cut through. The tester records the minimum cutting strength automatically.
3. How is the test monitored and displayed?
A dedicated computer software system displays real-time force, maintains the cutting force once the sample is cut through, and generates automated test reports. The force unit can be switched between N, kg, and lb.
4. Can the tester simulate high-temperature conditions?
Yes, the environmental box temperature is adjustable from 0°C to 150°C, allowing testing of wire insulation under elevated temperatures relevant to aerospace applications.
5. What safety features are included?
The tester automatically maintains cutting force and stops the test once the wire is severed, ensuring safe operation and preventing damage to the instrument. The servo motor with ball screw ensures precise and controlled force application.
