Glow wire testing instrument type GDP
The glow wire testing instrument is designed to simulate the effect of thermal stresses on solid combustible materials, materials used for electrical insulation or materials used in electrotechnical equipment. In reality, these thermal stresses can be produced by different kind of heat sources, e. g. glowing elements or overloaded resistors.
The instrument uses a glow wire, which is a specifi ed resistance wire, electrically heated to a defi ned temperature.
Equipment inclusively:
- Mounting plate of the test specimen
- Carriage
- Push pull cable
- Meter scale for the flame height
- Meter scale for the penetration depth
- Thermocouple
- Glow wire loop with drilling for thermocouple
