Low Smoke & Fume cable versus P.V.C. cable overloading test. Shed Experiment.

Cor, just look at this........... And P.V.C. is only rated at 70 degrees C. Or is it?

I am amazed that neither cable caught fire as such.

  • A good demo but not perhaps totally representative to heat only one core, usually the flow and return will be in the same cable and once they touch, the ADS should kill the power. Had he applied the welder power at one end and a short at the other, he would have probably found he did not need more than 100A to burn the insulation off the 2.5mm2

    The PVC problem is in part that the fumes are horribly poisenous, rather than just that there is a lot of smoke- not all smokes are equal ;-)

  • The cables did though take many seconds to actually become damaged. That surprised me. Admittedly the wires were in a cooling air flow designed to remove the fumes away from the test bench.
