Product Description

Product Introduction:

UL910/NFPA262 Steiner horizontal tunnel furnace is mainly used for the flame retardant performance test of CMP class wires and cables, and is mainly used for cables in horizontal subsystems that are laid directly in ventilated or forced ventilation environments without metal pipelines. This flame retardant test standard represents the most stringent flame retardant test standard of UL in the United States, and even the entire wire and cable flame retardant test, only the use of fluorine material sheath layer cable can pass this flame retardant test method. Due to the high decomposition temperature (more than 400 degrees) and high ignition point (more than 800 degrees), fluoroplastics are not easy to burn when the fire is not large, so it has better fire resistance than other organic materials. 

 

Technical parameters of tunnel furnace:

1. The combustion box is made of stainless steel, and refractory bricks are laid inside; Good thermal insulation performance. The internal dimensions of the combustion box are 305mm x 451mm, and the length is 7.6m;

2. The internal fixtures are made of SUS304 stainless steel, which is anti-rust and anti-corrosion;

3. The double-layer quartz glass observation window can observe the flame spreading distance, and display the position of the flame through the indicator light, which is more intuitive to record.

4. The height of the combustion box is suitable for personnel to watch the co5. The combustion box cover adopts the overall design, adopts the water tank sealing design according to the standard, and is equipped with a 2mm thick 304 stainless steel hot steel sealing tank to ensure that the flue gas does not leak during the test process.

6. The box cover is made of refractory materials and stainless steel materials, and the box cover is equipped with a hook and a hoisting box cover device;

7. The specimen holder is equipped with a cooling water circulation support bracket, which is resistant to high temperature and can support calcium silicate board and other combustion coverings;

8. SUS304 stainless steel insulation body cover, filled with high-temperature insulation material

9. Equipped with an escalator-type sample installation platform to facilitate installation, dismantling of samples and maintenance of furnace channels;

10. Stainless steel smoke exhaust pipe, beautiful and corrosion-resistant;   mbustion state and installation, and adjust the sample;

11. Independent multi-functional exhaust pressure detection device: real-time monitoring of exhaust pressure changes during the test process. The detection range is 0~250Pa, the accuracy is ± 0.5Pa, and the system indication pressure test accuracy is ±2Pa;

  12. Fan: 380V, 50Hz, 3Kw equipped with inverter to change the wind speed. The maximum flow rate is at least 8000m3/h, which can discharge the flue gas generated by sample combustion out of the outdoor in time to ensure the safety of the test;

  13. Double-head copper gas burner: the burner is 1320mm away from the air inlet, which can output the standard 5.3MJ/min heat, and can control the gas flow rate by the mass flow meter according to different standards, the measurement range is 0~160L/min, and the calorific value output of the burner can be changed, and the maximum output energy can reach 100MJ/min;

 14. Automatic ignition system: to ensure the safety performance of the test, high-voltage ignition, 12KV, 50mA, the minimum high voltage of the ignition electrode is 1.8kVp;

  15. Smoke density system: provide a separate signal processing system to ensure that the sensor is linear;

  16. Automatically record temperature and flue gas sensing signals, and the sample collection frequency is 1Hz;

  17. Mass flow controller: SUS316 stainless steel, maximum pressure 1000psi (70bar), leakage rate less than 1×10-7ml/s, calibrated by NIST, 0~5VDC and 4~20mA signal, loop protection, propane flow range 0~2.3g/s, control speed ≤2s, control accuracy of ±1%FS, repeatability ± 0.5FS, temperature range 0~50°C, humidity range 0~90%, digital displayThe gas supply meets the heat requirements of 5000Btu (5.3MJ)/min during the automatic control test, and the software automatically records the amount of gas used;

  18. Standard test software can automatically record test data such as wind speed, temperature, smoke density and so on.
