Brief introduction: Wire and cable fire test device based on GB/T19216.11-2003 requirements (replacement GB12666.6) and IEC60331-11, used to test the electric wire electric cable under the certain fire source and the time can continue to run in the specified state. Important parts adopt stainless steel, corrosion resistance of smoke, gas. A high degree of automation control system, with automatic ignition, the temperature and time digital display, easy observation records, stable and reliable use. Test of flame gas source using propane gas or liquefied petroleum gas. The test device is used for the following conditions: when the flame temperature of at least 750 ℃, and the test cable circuit integrity in exposed to flame. Features: 1. The burner for a type of Venturi mixer with propane gas burner, nozzle is 500 mm long, 15 mm wide, with a Venturi mixer 2. The burning hole three rows of staggered, burner front-end average width: 15 mm hole diameter: 1.32 mm hole center distance: 3.2 mm 3. Both sides of the nozzle plate each set a row of guide hole, keep the flame burning 4. With double flow meter and pressure regulation. 5. With a temperature measuring device (type K thermocouple). 6. Install a specimen holder end clamp sample, the other end of the convenient heat transmission along the longitudinal sample 7. Cable sample is supported by two metal rings, middle length is about 300 mm, two metal ring for other connecting parts 8. Samples supported metal ring inside diameter is 150 mm, ring cross section diameter of 10 + 2 mm 9. The location of the burner from burning the bottom not less than 200 mm, the walls and the distance of not less than 300 mm 10. Lower burner horizontal wheelbase cable sample for 70 + 10 mm, burner longitudinal vertical shaft about 45 mm wheelbase cable 11. Intelligent detection function, when the specimen during short circuit test of automatic alarm and turn off the fire. Technical parameters: Sample voltage: AC100V ~ 1000 v is adjustable Short circuit breakdown current sample: 2 a Maintain current sample: 0-260 ma is adjustable Power supply: the three-phase transformer: 380 v, 9 kva
