Roughly half of all copper mined is used to manufacture electrical wire and cable conductors.
3.
This document and its precursors were created due to a need for a standard definition of cable conductor size.
4.
The DC electric power for the LNB is provided through the same coaxial cable conductors that carry the signal to the receiver.
5.
However, the maximum length of bus is directly related to the gauge of the cable conductor and time delay of the transmitted signal.
6.
When multiple cables are in close proximity, each contributes heat to the others and diminishes the amount of external cooling affecting the individual cable conductors.
7.
The overall ampacity of insulated cable conductors in a bundle of more than three cables must also be derated, whether in a raceway or cable.
8.
In cables different conditions govern, and installation regulations normally specify that the most severe condition along the run will govern each cable conductor's rating.
9.
The method assumes a single fault exists, of low resistance compared with the undamaged cable insulation resistance, and that the cable conductors have uniform resistance per unit length.
10.
Copper is primarily used in coil windings in the stator and generators ( which convert mechanical energy into electrical energy ), in low voltage cable conductors including the vertical electrical cable that connects the nacelle to the base of the wind turbine, in the coils of transformers ( which steps up low voltage AC to high voltage AC compatible with the grid ), and in gearboxes ( which convert the slow revolutions per minute of the rotor blades to faster rpms ).
