Abstract

Oppfinnelsen angår en elektrisk varmekabel omfattende minst to elektriske ledere, en polymerblanding som har positiv temperaturkoeffisient (PTC) og en isolerende kappe. Hver leder er innbakt i et lag av PTC-polymerblandingen, de to lederne er vridd sammen for å danne en vridning, hvor varmeeffekten til kabelen er en funksjon av stigningen til vridningen, og vridningen er dekket av den isolerende kappen.
