2. Mineral-insulated copper-clad cable - Wikipedia

   en.wikipedia.org/wiki/Mineral-insulated_copper...

   The cable meets and exceeds BS 5839-1, making it fire-rated surpassing 950°c for over three hours with simultaneous mechanical stress and water spray as well without failure. MI cable is primarily used for high-temperature environments or safety-critical signal and power systems; however, it can additionally be used within a tenanted area ...

3. Plenum cable - Wikipedia

   en.wikipedia.org/wiki/Plenum_cable

   The fire requirements on riser cable are not as strict. Thus, plenum cable can always replace riser cable, but riser cable cannot replace plenum cable in plenum spaces. Both plenum and riser cables commonly include a rope or polymer filament with high tensile strength, which helps support the weight of the cable when it is dangling in an open ...
