Electrical cable for an appliance, appliance and method for producing an electrical cable

An electrical cable (1) for an appliance comprising

• a core bundle (21) comprising two core wires (10), each of the two core wires (10) comprising a center conductor (11) made of conductive strands and an insulation layer (13) on the outer periphery of the center conductor (11), the insulation layer (13) comprising a non-foamed softened polyvinyl chloride compound,
• an inner sheath layer (14) arranged around the insulation layers (13), the inner sheath layer (14) comprising a foamed softened polyvinyl chloride compound,
• wherein the foamed softened polyvinyl chloride compound of the inner sheath layer (14) contains a plurality of cells (16) consisting of gaseous inclusions in the polyvinyl chloride compound, and wherein each cell (16) is characterized by an equivalent diameter, wherein the equivalent diameters of the plurality of cells (16) form a distribution of equivalent diameters, the distribution having an average equivalent diameter, wherein the equivalent diameter of the cells located at an outer location of the inner sheath layer (14) is larger than the equivalent diameter of cells located at an inner location of the inner sheath layer (14), and
• an outer sheath layer (15) arranged around the inner sheath layer (14), the outer sheath layer (15) comprising a non-foamed, softened polyvinyl chloride compound and having a minimum thickness larger than the average equivalent diameter, and a maximum thickness of twice a maximum equivalent diameter of the plurality of cells (16).
