Abstract: The present invention relates to a cord structured to connect a power source to a power take-off. The cord comprises a conductor extending along a length of the cord between opposite ends thereof, an insulator secured in surrounding relation to the conductor and extending along a length thereof, at least one resistance wire connected to the insulator and extending along at least a majority of a length of the insulator, a switching structure connected to the resistance wire and structured to define an active connection of the resistance wire in current receiving relation to the power source, and a temperature sensor structured to sense temperature exteriorly of the insulator. The temperature sensor is connected to the switching structure and is operative therewith to establish the active connection on determination of a predetermined ambient temperature. The resistance wire heats the insulator upon establishment of the active connection.
