Wire and cable bundle combustion and heat release testing device

Product Introduction

The wire and cable bundle vertical combustion tester is designed according to the requirements of UL1685, GB18380.31 standards for wire and cable bundle combustion tests and other relevant regulations. And comply with IEC60332-3-10, KSCIEC60332-3-21~25 (Class A~D) standards. When a certain amount of gas is supplied to the box and a standard ignition source is used for ignition, this instrument can be used to test the vertical flame spread to the electrical vertical flame and the status of vertical cables and wires. In addition, if the burner of this tester is adjusted by 20 degrees, it can meet the IEEE383 (IEEE1202) testing standard. If equipped with a heat release instrument, it can also measure power values such as H.R.R (heat release rate), S.P.R (smoke generation rate), etc.

The heat release testing system is fully based on GBT31248-2014 and EN50399:2011 standards, and adds heat release testing smoke pipes, air intake pipes, and fans on the basis of GB18380.31 bundle combustion testing furnace. Test the combustion heat release performance of wires and cables.

Box characteristics
1. The size of the stainless steel test box is 1000 ± 100 (W) x2000 ± 100 (D) x4000 ± 100 (H) mm. The inner surface of the box is higher than the ground, and there is insulation material laid on the back side.
2. Equipped with standard stainless steel ladders according to GB/T18380.31 requirements; One set of 800mm wide ladder and one set of 500mm narrow ladder;
3. The material of the steel ladder is stainless steel; Corrosion resistance; Easy to clean;
4. At the lower part of the box, there is an air inlet of 800 ± 20 (W) × 400 ± 10 (D) located 150 ± 10mm in front of the box.
5. An imported K-type armored thermocouple with a diameter of 2mm is installed inside the box;
6. The top of the box is equipped with an anemometer; Monitor the wind speed environment outside the combustion chamber; 7. 7.There is a 300 ± 30 (W) × 1000 ± 100 (D) exhaust port on the top of the box, which facilitates the elimination of smoke during the testing process; Adjustable wind speed of 10m/s;
8. Equipped with one standard electrical control cabinet;
9. Stainless steel exhaust pipes and related accessories;

Combustion system:

1. Burner: belt type propane gas spray lamp, size 257mm × 4.5mm, with a total of 242 holes arranged in three rows, with 81, 80, and 81 holes respectively. The diameter of the holes is 1.35mm, and the distance between the holes is 3.2mm;
2. Imported AGF spray lamp wick from the United States, length 257mm;
3. High precision ball valve, controlling gas on/off;
4. Flow meter: inlet air flow and gas flow meter and control valve; Under 100kpa and 20C conditions: air flow velocity: (77.7 ± 4.8)
L/min; Propane (13.5 ± 0.5) L/min;
5. Imported brand pressure gauges and pressure regulating valves;
6. Automatic ignition device;
7. Combustion angle: 20 degrees;
8. The air and gas flow rates in the burner must supplement the temperature and pressure, which many traditional systems ignore. The gas and air compensation process can be automatically completed through computer programs.
