Cable systems for renewable energy integration
We sometimes forget that many cables are not designed to conduct electrical power or signals, such as cables which support bridges, actuate ailerons, and tow cars, for example. There are, however, similarities between mechanical and electrical wire and cable — at least in terms of their means of manufacture. As strands of wire are made, they are drawn through progressively smaller dies. This is true of all wire. Diamond dies are used, due to their extreme hardness, and the fact that they retain their precision size for a long time.
Because soldering copper can be difficult unless a flux is used which can leave corrosive residues behind , it is usually tinned or plated if it is intended to be soldered. This does not preclude the use of flux, but the coating makes soldering easier, and affords some protection against corrosion overall.
Bare copper is perfectly suited for pressure terminations crimping, etc. To start with, the physical attributes of wire are only part of the story. Years ago, when copper was in shorter supply, aluminum was often chosen for residential wiring. What was not fully appreciated at the time was the serious effects of the galvanic reaction between aluminum and the brass or copper fittings or terminals in the presence of moisture. This would develop corrosion which would cause failure at the connection, either in the form of an open circuit or, worse, a high resistance, which spawned many a fire.
Aluminum proved to be galvanically too aggressive to be placed in direct contact with copper or brass. The same problem exists in other circuitry. If all terminations were changed to aluminum, the galvanic problem might be solved, but this would apply to all the pins, terminals, contacts, and conducting hardware, and there are a lot of existing systems which would need adaptation. Then, too, aluminum develops a hard layer of oxides on its surface, and this must be penetrated for a good electrical connection.
These solve the galvanic action problem which compromises fire safety. One other serious deficiency of aluminum is that it cannot be easily soldered or plated to improve solderability. All this may suggest there is no legitimate use for aluminum in electrical systems, let alone on aircraft. Not so. In truth, aluminum is approved for airborne use in 6 AWG or larger gauges.
This is aimed at power applications, not avionics systems. At the high currents appropriate to large conductors such as these, the effects of possible corrosion are compensated to some extent by the current itself.
As a result, it is often used as a coating for copper in order to improve skin conductivity and offer some protection against corrosion. Silver is also readily soldered. It is, of course, eminently solderable.
Gold , though pricey, is a common plating for brass connector pins, ARINC coax contacts, and parts of some other connectors. Fundamentally, this is the plating of choice because of its excellent corrosion resistance properties in applications where there can be great exposure.
Gold is also a good conductor and easily soldered. Other good, and approved, choices exist and are readily available. Temperature ratings reflect the range within which the integrity of the insulation will be maintained — sufficiently flexible when cold and free of the effects of softening or disintegrating at the high end of the scale.
It should be noted that the upper temperature rating should take into account the heat rise caused by power dissipation in the conductor itself. Other insulation properties of concern, depending upon the applications, include the dielectric constant, which dictates loss, mutual capacitance between conductors , impedance, velocity of propagation, etc.
Their usefulness is flawed by the use of polyethylene as the dielectric material. Certainly way above human tolerance.
Decidedly not. The reason is performance — maybe not at the outset but over time. In a great many aircraft, cables snake through the airframe in places that can become much hotter than the cabin.
What damage? A little background: Coaxial cables are, by definition, co-axial — that is to say, the cylinder of shielding and the cross-section of the center conductor share the same axis. The space [dielectric] between them is the same all the way around. Lower temperature dielectric materials soften at relatively low temperatures and inevitably the center conductor migrates off-center, toward the shield, in the direction of gravity or the inside of a bend in the cable.
This is permanent and just part of the damage that can happen. The other part occurs at the box. In the case of a receiver, changes in impedance can cause a reduction in signal — possibly to the point of loss of usefulness. In the case of a transmitter, things can get worse. The reflection of power [measured as SWR, or Standing Wave Ratio] comes right back to the final stage, producing heat … and heat is the arch-enemy of all electronic components. This is an invitation to the bench for repairs.
Some low-loss cables use foamed polyethylene which is soft to begin with. Cable routing with careful attention to avoiding hot spots is important in general, but crucial with such cables. Cable Materials.
A power cable is an electrical cable , an assembly of one or more electrical conductors , usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed. The first power distribution system developed by Thomas Edison in in New York City used copper rods, wrapped in jute and placed in rigid pipes filled with a bituminous compound.

Fire-resistant cables for electrical installations are designed to distribute electrical energy to the electrical installations at stationary laying in power and lighting electrical networks, as well as for the installation of electrical equipment, machines, tools and machine tools, domestic electrical installations, for installation outdoors and inside industrial buildings, hollow channels of building structures hidden under the plaster lining. The wire is used for the installation of electrical circuits, the power electric motors, various industrial and laboratory equipment, and portable devices. Modification: for single installation; flame retardant at installation, with low smoke and gas emission; cold-resistant. The cables do not spread combustion at group, stationary laying of cable lines, in the absence of mechanical effects on cable and they are able to operate when exposed by the flame for at least minutes. They are designed for wirings and circuits of emergency power and power equipment current collectors in public buildings, in the operating departments of hospitals, in offices equipped with computers and microprocessor technology, entertainment complexes, sports facilities and other facilities with high demands on fire security.
