Four- cubic ventilation hood Cable burning testing instrument (The level of vertical burning)
Overview:
l This test equipment used to test the wire and cable under the overheating and the over-flow and other unnormal conditions, the flame retardancy function of the insulation layer.
l The tester is composed by the test part and control part, using the integrated design, to facilitate the installation at the scene and debug. The automatic degree of control system is high, has automatic ignition function, temperature and time figures show, so that the observation and records are facilitate and the use of it is stable and reliable.
l Power supply: AC220V±10%/50Hz.
l According to the standard: UL1581 and UL224 (The level of vertical burning)
l The average volume: Four m3 (the size of out appearance: 1.1x2x2.1m)
l The gas&nbs******bsp;liquefied petroleum gas use as the source gas of the pilot flame (Under the conditions of the proposed, suggest the elect of temperament better gas).
l The inner diameter of the burner is ￠ 9.5 ± 0.5mm, 100mm long, has the air-conditioned hole.
l The height of the flame is moderate, can be set from 20mm to 175mm.
l The angle of the flame test is adjustable from 0～45. After the burning of the test, the burner nozzle will be turned over 90 degrees, and turn to the direction side.
l The exclude fan select the metal which is manufactured by industrial grade, installed the unidirectional wind sealing plate between the exhaust duct and fan, the extensions can be removed to clean.
l The devices of the fixed test goods basically not affect the contact of the embers and the cotton.
l The imposing time and holding time of the flame can be adjusted in the scope of 0 to 99 minutes and 99 seconds.
l With a gas pressure regulator and flowmeter(automatic ignition)
l With temperature measurement device.
l Observation the window from the of front the glass is the transparent one, and with one pair of sealed gloves, the distance between two gloves is 500mm. the distance from the gloves to the base of equipment is 300mm.
