摘要：An electrical three-phase heating cable and system that produces a reducedmagnetic field and which uses a cable containing three insulated copper wires, orequivalents, as heating elements. The wires are equidistantly spaced from each other, intriangular configuration, the geometric center of the triangle coinciding with thelongitudinal axis of the cable. The wires are twisted in a uniform fashion along thelongitudinal axis of the cable. Its low operating temperature, robustness and safetyenable the system to be installed, for example, in floors and walls for the generalheating of buildings, and in outdoor pavements, for snow-melting purposes, etc. Thefeeder conductors are also twisted to reduce the magnetic field around the feeder.
