Utilities
Propane Gas Valve System
• The burner has a Ventury Mixer structure and it’s a ribbon type propane gas burner with a front length of 500mm
• Structured with 3 rows of cross holes, Average front width of burner: 15mm, Hole diameter: 1.32mm, Distance between the center: 3.2mm.
• Allows a polished hole row in pilot hole for flame preservation in both faces of Burner plate
• A sample support is fixed with a clamp on the side to avoid movement and the other side allows heat spread in length.
• The central part of the cable is approx. 300mm separated and it’s supported by two metal rings. Besides the 2 metal rings there are other ground connected parts.
• The internal diameter of sample support ring is approx. 150mm made of metal, round shape with a 10±2mm diameter.
• The front of Burner position is located to be at least 200mm from chamber floor or at least 300mm from chamber’s wall surface.
• The horizontal axis of burner is located 70±10mm downwards from lowest part of sample cable and vertical axis of burner is located approx. 45mm from the vertical axis.
• Two thermocouple(A,B) are horizontally installed separated 45mm left and right of burner center-line to check if ignition input is within 750+50℃.
• Add for KWA 409(Korea Wire Shipbuilding Industry Cooperative) of Fire resistance test(options)
• It has 2 type of mode which manual mode by control panel and auto mode by computer software.
Before order, user can select it. It is customizing. And if order IEC 60331-11,12 and BS 6387, user can use one Slidacs system(various up to 1,000V power supplier). Cost should be down.
• Cable test description
• Manufacturer
