METHOD FOR MANUFACTURING POWER TRANSMISSION LINE WITH SPIRAL CROSS-SECTION AND DEVICE BASED ON ITS BASIS Russian patent published in 2021 - IPC H02G5/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the transmission of high values of currents with constant and / or alternating voltage, from one and/or several sources to one and/or several consumers of electricity. A method for manufacturing a power transmission line with spiral cross-section includes the step of winding in a spiral several electrically conductive plates of the same width, which are conductors of electrical energy and covered with an insulating material, and the step of attaching the connectors to the electrically conductive plates, while at the step of winding the electrically conductive plates are wound with a predetermined number of revolutions N for a hollow cylinder together with an insulator of thickness w, having an adhesive layer on both sides, in a defined manner as disclosed in the invention. The power transmission line device includes electrically conductive conductors formed by positioning in the longitudinal direction the first and second electrical conductors mutually adjacent to each other and terminals that are connected to the first and second electrical conductors at both ends and are made in a certain way.

EFFECT: reduction of parasitic parameters due to a decrease in the linear inductance and increased linear capacitance of the spiral in the cross section of the transmission line.
