The invention relates to a cable technology, in particular to a flat electrical cables, and can be used as a universal flat cable for high conductivity for electrical receivers of electric current, signaling telephone, TV, computer, and radio.

Famous strip cable (USSR Author's certificate (11) 599285, (51) M CL N 01 7/08)containing two metal strip, between which there is an insulating tape.

Also known flat electrical cable (Patent (19) SU (11) 1749915 A1 (51) 5 N 01 7/08) with symmetrically arranged relative to the longitudinal axis of the flat insulated conductors is selected as the closest equivalent.

The specified cable has a greater cross-sectional area, and cannot be used for transmission of television signals, computer and radio.

The aim of the invention is to increase the conductivity of the cable while power receivers of electric current, and signaling telephone, TV, computer, and radio.

This is achieved by the design of the cable, which contains one (Fig.1a) or more (Fig.1b) (depending on transmit power and number of consumers) identical sections. The section consists of a Central flat currents is the leading wires 1, located between two flat insulating tape 2, which in turn are between two zero flat conductors 3. The distance d should be not less than the thickness of the insulating tape 2. The cable also has an outer insulating sheath 4 and, if necessary, may have a grounding shell 5.

Power receivers of electric current, and signaling telephone, TV, computer, and radio communication is performed through the transmission of electromagnetic energy along the surface of conductors. The proposed cable design allows you to maximize the surface area lived at the minimum cross-sectional area of the cable, the zero conductor shield radiation transmitted electromagnetic energy outside of the cable and protects data transmitted over cable signals from external interference. All this leads to a reduction of losses and eliminates interference with the transmission of electromagnetic energy.

Flat electrical cable containing a flat conductor and the zero conductor, insulated between each other, characterized in that it contains one or more identical sections, consisting of a Central flat conductive wires placed between two flat insulating tapes, which, in turn, are between two zero flat conductors having a width greater than the width conductive the silts on the double thickness of insulating tape.

FIELD: printed-circuit boards, multilayer conductors, and ribbon cables.

SUBSTANCE: proposed method involves spatial disposition of conducting communication lines which makes it possible to compensate for electromagnetic pickups in three-phase power circuits caused by self-induction and is based on compensating effect attained by superimposing electromagnetic inductances shifted in phase due to phase shift of currents carried by three adjacent conductors; novelty is that only positive (forward) currents carried by three adjacent layers and shifted in phase through 120 deg. are used in three-phase circuits. Passing three-phase current of same amplitude through three adjacent conducting tracks disposed strictly in parallel one on top of other in these three adjacent layers where columns built of conducting tracks occurring in three layers are formed we shall obtain equal-amplitude vectors in each layer using cyclic phase transfer; these vectors correspond to harmonic oscillations on vector diagram from all three phases (A, B, C).

EFFECT: maximized compensation of noise caused by self-induction.
