The Burning Behaviour of Bunched Cables is a method to determine the vertical flame spread characteristics for a number of cables that are bunched together in a ladder. Burning Behaviour of Bunched Cables consists of • Stainless steel made test chamber has an inner dimension of 1000mm by 2000mm by 4000mm. The chamber wall was inserted with 65mm of mineral wool for thermal insulation. • The bottom of the chamber is higher than the ground, there is an 800mm by 400mm air inlet at the bottom of the chamber at 150mm from the front wall, with a grilling placed above. • A 300mm by 1000mm exhausting opening at the top of the chamber for removal of gases during the test. • There is a high-temperature resistant observation window on the front door and the side of the test chamber for watching during the test. • Equips with OMEGA K type insulated thermocouples, for measuring the test chamber temperature. • Chamber air supply system, consists of a blower, inverter, stainless steel U-shape tube, anemometer. • Stainless steel made tubular steel ladder, width in 500mm and 800mm. • AGF ribbon-type propane gas burner, with venturi mixer. • Two sets of propane mass flow controller and air mass flow controller, providing a standard burning flame, accuracy less than ±1%.
