Wire & Cable Bundle Combustion Tester

Scope of application:

It is used to evaluate the ability of vertically installed bundled wires and cables or optical cables to inhibit the vertical spread of flames under specified conditions, and the use process needs to cooperate with smoke dust removal towers. The whole machine is composed of several parts, such as a test chamber, an air source, a steel ladder, an emission purification system, and an ignition source.

Conform to the standard:

As per standard IEC60332-3-10- 2000.

Technical Parameters:

1. Test chamber

2. Air source

3. Steel ladder type

4. Discharge purification device

6. 2 strip standard propane burner devices

7. 2 venturi gas mixing devices

8. The pressure gauge and pressure reducing valve device can adjust the propane and air pressure to 0.1Mpa

9. The rotameter adjusts and sets the gas flow rate

10. The box provides steel ladders and railings, which are convenient for users to detect at the top

11. Equipped with a ball valve to manually close the air source

12. Automatically set the combustion test time, and automatically cut off the gas source at that time

13. The thermocouple on the inner wall of the box can display the internal temperature of the box

14. Combustion box dimensions: 1120 (W) X2195 (D) X5077 (H) mm

15. Control box dimensions: 1280 (W) X770 (D) X1200 (H) mm

16. Power supply: AC 220V, 50/60Hz, 2A

17. Air source: propane, air (provided by the customer).

The significance of testing:
The cables tested according to IEC 60332-3 have been proven to effectively suppress the vertical spread of flames during bundled installation, thereby saving valuable time for personnel evacuation and firefighting in the event of a building fire. This is a key indicator for measuring the flame retardant safety of cables.
