The vertical horizontal combustion test machine of the wire and cable is the standard of the UL1581, UL13, UL444, VW-1 of UL1655, and the FT-1 of CSA. Check the burning test of various wires and cable insulation materials, print circuit board materials, IC insulation and other organic materials. Many current wires and cable companies are equipped with the test apparatus.1. Work principleWire and cable vertical horizontal burning test apparatus consists of two parts: burning test box and control cabinet. The main function of the wire and cable vertical horizontal combustion test machine is to generate standard flames for testing, as well as functions such as the burning space of the flame retardant cable, the auxiliary temperature measurement method, and the time measurement. The control cabinet is a device that generates more than 5 times the current working current of the cable. The working current of (10~5000)A can be generated according to the measurement requirements.2. Calibrate standard equipmentCalibrate the mining cable load burning test apparatus, the following standard equipment must be available:(1) Steel rolls ruler (0 ~ 5) m: 1 pcs(2) Vernier Caliper (0 ~ 150) mm: 1 pcs(3) The range is (0~100)A, (0~500)A, (0~1000)A, (0~5000)A standard electrical sensor 1 for each, or multiple range standard sensor 1 pcs; ammeter above 0.2 level 1 pcs.(4) The thermocouple test device. The range is (0~1300) ℃.(5) Secondary meter calibration: The standard signal of the K -t
