Abstract
A method for producing a self-regulating heating cable is provided. A first conductive constituent is cryogenically cooled to a temperature at least as low as its glass transition temperature, and ground into first conductive pellets. A second conductive constituent is cryogenically cooled to a temperature at least as low as its glass transition temperature and ground into second conductive pellets. The first and second conductive pellets are combined to obtain a mixture which is extruded over a pair of conductive wires to form a cable.
