The invention relates to an electrical cable (1) for an appliance, especially a vacuum cleaner. The cable (1) comprises 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) and wherein each cell (16) is characterized by an equivalent diameter, in particular the diameter of a sphere having the same volume as the cell (16), 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. The invention further relates to an appliance with such a cable (1) as well as to an method of manufacturing the cable (1).

Provided is a semiconductive resin composition which may be used for both an internal semiconductive layer and an external semiconductive layer of a power cable, and in particular has excellent peelability to be used for the external semiconductive layer. In addition, a novel semiconductive resin composition having improved thermal resistance and mechanical physical properties, and an improved deterioration property is provided. The semiconductive resin composition for a power cable includes: 20 to 70 parts by weight of any one or two or more conductive particles selected from the group consisting of carbon black, graphite and graphene, based on 100 parts by weight of a composite resin including a polypropylene homopolymer having a melting point of 150 to 170 C. and an ethylene-(meth)acrylate-based resin.

A method of forming a plurality of individual heating cables sets includes creating at least a portion of a master cable set by coupling alternating sections of cold and hot cable section, each section of cold cable section having a length twice a model cold cable section length and each section of hot cable section having a length twice a model hot cable section length. A continuous metallic ground sheath is applied about substantially all of the master cable set and a continuous outer jacket is applied about the continuous metallic ground sheath. The master cable set is segmented at defined locations to create a plurality of individual heating cable sets having an overall length of the model hot cable section length plus the model cold cable section length.

The invention provides processes for making a coaxial device by simultaneously extruding a polymer encapsulation layer defining a hollowed area and filling the hollowed area with PCM composition in liquid form. The invention is useful for thermal management in a variety of applications in such as, for example, automotive, building, packaging, garments, and footwear.
