Power Cords

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.

The Commission has determined that extension cords for indoor and outdoor use that do not contain one or more applicable readily observable safety characteristics minimum wire size; sufficient strain relief; proper polarization; proper continuity; outlet covers for indoor cords ; and jacketed cords for outdoor cords present a risk of electrical shock or fire and constitute a substantial product hazard. Extension cords see figure 1 are used for extending the electricity supply of an electrical outlet or receptacle to a portable corded appliance or device, such as a toaster, a lamp, a television, or a leaf blower. Extension cords have receptacles or outlets molded into the cord itself, whereas power strips and taps have flexible cord but receptacles or outlets are not molded into the cord itself. The following table provides a non-exhaustive list of examples of extension cords that fall within and outside the scope of the rule.
