2. Trace heating - Wikipedia

   en.wikipedia.org/wiki/Trace_heating

   The heating element is then normally soldered to the exposed conductor wire which creates a small heating circuit; this is then repeated along the length of the cable. There is then an inner jacket which separates the bus wires from the grounding braid. In commercial and industrial cables, an additional outer jacket of rubber or Teflon is ...

3. Underfloor heating - Wikipedia

   en.wikipedia.org/wiki/Underfloor_heating

   There is a likelihood that underfloor heating may add to offgassing and sick building syndrome in an environment, particularly when the carpet is used as flooring. [citation needed] Electric underfloor heating systems cause low frequency magnetic fields (in the 50–60 Hz range), old 1-wire systems much more so than modern 2-wire systems.

4. Underfloor air distribution - Wikipedia

   en.wikipedia.org/wiki/Underfloor_air_distribution

   Underfloor air distribution is frequently used in office buildings, particularly highly-reconfigurable and open plan offices where raised floors are desirable for cable management. UFAD is also common in command centers , IT data centers and Server rooms that have large cooling loads from electronic equipment and requirements for routing power ...

5. Electric heating - Wikipedia

   Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators. Alternatively, a heat pump can achieve around 150% – 600% efficiency for heating, or COP 1.5 - 6.0 Coefficient of performance , because it uses electric power only for ...

6. Overhead power line - Wikipedia

   The optimization problem is made more complex by additional factors such as varying annual load, varying cost of installation, and the discrete sizes of cable that are commonly made. [ 2 ] [ 11 ] Since a conductor is a flexible object with uniform weight per unit length, the shape of a conductor strung between two towers approximates that of a ...
