• Steel structure box, frame structure, stable and beautiful

  
  

• Combustion device and control box, gas distribution cabinet and distribution cabinet are designed separately, which is convenient for laboratory layout and ensures the safety of equipment.

  
  

• The heat source is a ribbon propane burner torch with a nominal nozzle length of 500mm

  
  

• The combustion holes are staggered in 3 rows, the average width of the front end of the burner: 15mm, the hole diameter: 1.32mm, and the hole center distance: 3.2mm. A row of guide holes are set on both sides of the nozzle plate to keep the flame burning

  
  

• The position of the burner torch is not less than 200mm from the bottom of the combustion box. The height of the burner can be adjusted up and down to meet the test requirements of samples with different wire diameters, and the distance from the box wall is not less than 300mm.

  
  

• The distance between the horizontal axis of the burner torch and the lower end of the cable sample is 70±10mm, and the distance between the longitudinal axis of the torch and the vertical axis of the cable is about 45mm

  
  

• According to customer needs, it can be equipped with MFC or high-precision rotameter to provide gas and auxiliary combustion air to the torch

  
  

• Equipped with Venturi to fully mix air and gas to meet combustion needs

  
  

• Equipped with brand pressure gauge and pressure regulating valve to adjust gas pressure, equipped with solenoid valve to control gas on and off, to ensure the safety of equipment use.

  
  

• High voltage pulse automatic ignition, stable ignition, safe and reliable

  
  

• The cable sample is supported by two metal rings, the middle length is about 300mm, and the other connecting parts are other than the two metal rings. The inner diameter of the sample supporting metal ring is 150mm, and the diameter of the ring section is 10±2mm.

  
  

• Two thermocouples (A, B) are installed horizontally on the left and right sides 45mm away from the center line of the burner, and check that the flame temperature is within 750+50°C

  
  

• Thermocouple rack can be adjusted horizontally and in height

  
  

• There are two operating modes, the manual mode is controlled by the panel, and the automatic mode is controlled by the computer software

  
  

• Computer + professional software control and guide the test process, easy to operate, safe and reliable
