Abstract (en)
[origin: CA2890683A1] The invention relates to an arrangement of a plurality of electrical conductor pairs (3) for symmetrical supplying of a consumer, in particular of a capacitively compensated conductor loop for inductively heating deposits of substances comprising hydrocarbons, such as oil sand, bitumen, heavy oil, natural gas, shale gas, and a shield pipe (4) enclosing the substances, wherein supply (1) and return (2) lines of the conductor pairs (3) are alternatingly concentrically and/or uniformly distributed within the shield pipe (4) enclosing the plurality of conductor pairs (3). The eddy currents occurring in the shield pipe (4) and the consequential losses are thus minimized.
