Abstract

A laminar electrical heater in which at least one of the electrodes is in the form of an elongate element forming part of a fabric and which comprises a PTC element, e.g. of a conductive polymer, to render the heater self-regulating. Preferably the heater is prepared by weaving together (a) a first elongate element comprising a first electrode (1) and a layer (11) of PTC conductive polymer surrounding that electrode, and (b) a second elongate element comprising a second electrode (2). The resulting fabric can if desired be laminated to a sheet of a ZTC (3) conductive polymer. A shrinkable fabric heater can be made by incorporating a heat-shrinkable non-conductive filament (4) into the fabric, perpendicular to both electrodes, and is useful for example for enclosing splices in telephone cables.
