2. Mineral-insulated copper-clad cable - Wikipedia

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

   MI cable is only manufactured with ratings up to 1000 volts. The magnesium oxide insulation has a high affinity for moisture. Moisture introduced into the cable can cause electrical leakage from the internal conductors to the metal sheath. Moisture absorbed at a cut end of the cable may be driven off by heating the cable.

3. Trace heating - Wikipedia

   en.wikipedia.org/wiki/Trace_heating

   Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables. Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe.

The metal pieces may be a covering on a structural, non-waterproof roof, or they could be self-supporting sheets.

6. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   Some types of metal conduit may also serve as a useful bonding conductor for grounding (earthing), but wiring regulations may also dictate workmanship standards or supplemental means of grounding for certain types. While metal conduit may sometimes be used as a grounding conductor, the circuit length is limited. For example, a long run of ...

7. Electric arc furnace - Wikipedia

   en.wikipedia.org/wiki/Electric_arc_furnace

   The key is the electrical resistance, which is what generates the heat required: the resistance in a steelmaking furnace is the atmosphere, while in a submerged-arc furnace, the slag (or charge) supplies the resistance. The liquid metal formed in either furnace is too conductive to form an effective heat-generating resistance.
