Abstract

A low resistance surface conducting conductor electric cable comprising a plurality of layered elongated sheets (1) of electrical conducting material. Each sheet is individually insulated (2) and the cable includes an outer insulating layer (3). The resistance of the conductive sheets can be progressively reduced to superconductivity by increasing the conductive sheets to critical ratio of cable length to aggregate perimeter length of cross-sectional area of the conductive sheets. In an alternative embodiment (figure 2) the sheets are folded in a concertina-shaped manner. The invention makes uses of the discovery electric current is conduct over the surface of a conductor and is related to the electrical resistance, the resistivity, the length and the perimeter of the cross-sectional area of the conductor in the form: R=ςL/P, where R is the resistance of the conductor, ς is the resistivity of the electrical conducting material, and P is the perimeter of the cross-sectional area of the conductor.

Description

LOW RESISTANCE SURFACE CONDUCTING CONDUCTOR ELECTRIC CABLE
This invention relates to a low resistance surface conducting conductor electric cable.
The electric cable is well known for the transmission of electric power and electric signal in the form of electric current. The electric cable comprises an electrical conductor, such as copper, in the form of a wire insulated or uninsulated along its length forming a single core electric cable, or wires individually insulated or uninsulated twisted together along its length forming a multiple core electric cable.
When electric power is transmitted along the conductor of an electric cable there is a loss of power equal to the electric current squared and the product of the electrical resistance of the conducting material from which the conductor is made. The power loss can be minimized by reducing the amount of electric current being transmitted by transforming it down whilst substantially maintaining the electric power being transmitted and or by reducing the electrical resistance of the electrical conductor, ideally to zero, by utilizing the relationship between the electrical resistance of the conductor, its resistivity, its length and its cross- sectional area, which assumes electric current is conducted through the conductor, in the form of the following equation:
R = pL a
Where,
R = the resistance of electrical conductor measured in ohms. p = the resistivity of electrical conductor measured in ohm-meter.
L = the length of electrical conductor measured in meters. a = the cross-sectional area of electrical conductor measured in meter^ From the equation the electrical resistance can be reduced to a level of near zero or superconductivity, if the and length of the conductor remains constant, by reducing the resistivity of the conducting material by using a low resistivity conducting material and or super-cooling the conducting material near to a temperature of absolute zero, or by increasing the cross-sectional area of the electrical conductor but the resulting cable would be expensive and impractical. I have discovered and proved by experimentation that electric current is conducted over the surface of an electric conductor at all frequencies, which has resulted in the electrical, the resistivity, the length, and perimeter length of cross-sectional area being related in the following way.
R = pL P
Where,
R = the resistance of the electrical conductor measured in ohms, p = the resistivity of the electrical conductor measured in ohms,
L = the length of the electrical conductor measured in meters and
P = the perimeter of the cross-sectional area of the electrical conductor measured in meters
It is on this premise that the following invention is based.
According to the present invention there is to be provided a low resistance surface conducting conductor electric cable comprising at least two layers or conductive sheets of electric conducting material, which can be a minimum thickness of one atomic diameter of the electric conducting material, each sheet being separated and can be enclosed by an electric insulating material, which can be of minimum thickness of one atomic diameter of the electric insulating material, the electric resistance of the conducting material being directly proportional to the ratio of the length of one the conductor layered sheets or the cable length and the aggregate perimeter lengths of cross-sectional area of the conductive sheets can be progressively reduced to superconductivity, by increasing the aggregate perimeter length of cross-sectional area of the conductive layered sheets and keeping the cable length constant by increasing the number of conductive layers or sheets to a critical ratio of cable length and the aggregate perimeter length of cross-sectional area of the conductive layered sheets.
The invention embodies a plurality of elongated sheets which may be arranged in separate mutually parallel planes or layers. Each sheet is electrically insulated from the other may be individually insulated and may include a further insulating layer.
Another embodiment of the invention comprises a sheet of elongated electric conducting material suitably electrically insulted and folded in at least one undulating or concertina-shaped manner, which may include a further outer insulating layer.
Another embodiment of the invention comprises alternate sheets or layer of electric conducting material and electric insulating material with the insulating material at the beginning and at the end of the alternations, which may include a further outer insulating layer.
Specific embodiments of the invention will be described by way of examples with reference to the accompanying diagrams in which:
Figure 1. Shows the first embodiment of the cross-sectional area of the electrical cable. Figure 2. Shows the second embodiment of the cross-sectional area of the electrical cable.
Referring to the drawings fig.l the electric cable comprises strips of electrical conducting material 1 (four in this example) individually insulated 2 and layered one on top of the other or layered multiply one on top of the other separated by insulating material all enclosed by insulating material 3 along the length of the cable (not shown).
Another configuration of the electric cable fig.2 comprises a continuous sheet of electrical conducting material 4 across the cross-sectional area of the cable covered completely with insulating material 5, folded in a undulating or concertina-shaped manner enclosed by insulating material 3 along the length of the cable (not shown). The electrical conducting material of the cable can also be configured in the form of continuous sheets individually insulated across the cross-sectional area of the cable layered one on top of the other and folded in a undulating or concertina-shaped manner (four in this example) and enclosed by insulating material along the length of the cable (not shown).
