The wire and cable vertical and horizontal burning test apparatus is in accordance with UL 1581, UL 13, UL 444, UL 1655 VW-1 and CSA FT-1 standards. Test the burning resistance of various wire and cable insulation coating materials, printed circuit board materials, IC insulators and other organic materials. At present, the inspection rooms of wire and cable enterprises are equipped with this testing equipment. 1. Working principle of vertical and horizontal burning test apparatus for wire and cableVertical and horizontal burning test apparatus for wire and cable is composed of two parts: a burning test chamber and a control cabinet. The main function of the wire and cable vertical and horizontal burning test instrument is to generate a standard flame for testing, and to accommodate the burning space of the flame-retardant cable, the attached temperature measurement method, time measurement and other functions. The control cabinet is a device that generates a current that is more than 5 times the rated working current of the cable. According to the measurement requirements can generate 10A ~ 5000A working current. 2. Standard equipment for calibrationTo calibrate the mine cable load burning test apparatus, the following standard equipment should be available:(1) A steel tape measure (0-5) m.(2) One vernier caliper (0-150) mm.(3) One standard electric transformer with a
