45° Wire and Cable Combustion Tester
The 45° Wire and Cable Combustion Tester is a precision instrument designed to evaluate the flame resistance of low-voltage primary cables used in ground vehicles, rated for DC 60 V (AC 25 V) or below. The system integrates a control box, combustion chamber, burner, solenoid valve, high-voltage igniter, gas piping, and signal control lines. The instrument allows standardized, repeatable flame exposure to assess after-flame, ignition, and flame propagation characteristics of cables for safety compliance.
Applications
This tester is suitable for flame testing of:
Automotive low-voltage wires: primary wiring harness cables for passenger cars, trucks, and buses.
Electric vehicle cables: battery and power distribution cables requiring fire safety verification.
Vehicle interior wiring: ignition, lighting, and control system wires.
Insulated copper and aluminum conductors: for testing cable insulation under flame exposure.
Industry use cases: QC testing in automotive manufacturing plants, R&D labs for cable development, and safety testing agencies.
