Abstract (en)
An electric radiator made by the assembly of aluminium elements (1), made with die-casting or extrusion technology characterized in that a heating element used is of the heating cable type, said heating cable comprises: a heating wire (11); a first external silicone sheath (10) wraps the heating wire forming the main insulation; a second silicone sheath (9) forms the secondary insulation and wraps the first external silicone sheath (10); said heating cable is suitably shaped so that it can be inserted into the cavities (15) of said radiator with U-shaped shapes (12) inserted in the cavities (15) of the radiator elements; the inside of each cavity (15) is filled by casting with a mixture of marble aggregates and calcium sulphate powder which is made in a cold solution by mixing fine powders of calcium carbonate and calcium sulphate with water.
