Product Information:

The Fire-Resistance Cable Burning Test Apparatus (Cable Fire Integrity Tester) is designed to evaluate the ability of mineral-insulated cables and cables with fire-resistant layers to maintain circuit integrity under flame exposure. The apparatus subjects the test sample to a controlled gas flame under specified temperature, time, and electrical loading conditions, monitoring for short circuits or open circuits. This allows assessment of the cable’s fire-resistance performance. The system is suitable for type tests, factory inspections, and research verification of fire-resistant cables.

Accessories and Consumables

Testing Principle

During the test, the mass flow controller precisely adjusts the gas-to-air ratio, producing a stable and controllable high-temperature flame. The test cable is subjected to continuous flame while all cores are energized at rated voltage and a load current close to 0.1 A.

A continuous monitoring system observes the circuit status in real-time. Any short-circuit or open-circuit condition triggers an immediate signal, allowing evaluation of whether the sample maintains circuit integrity under the specified flame and loading conditions.

Operation Instructions

Ensure all gas lines, air lines, and exhaust systems are properly connected before testing.

Set the gas flow, air flow, and test duration according to the relevant standard.

Activate the exhaust system before ignition to ensure combustion gases are removed.

Do not open the test chamber door during testing.

For water-spray or water-jet fire tests, calibrate the flow meters and verify the tray setup before ignition.
