Abstract
An electrical heater suitable for heating a hot-melt adhesive to seal a cable splice case. The heater is in strip form and comprises a conductive polymer between two electrodes. The conductive polymer has a positive temperature coefficient of resistance and is thereby self-regulating. Current in-rush when the heater is cold is reduced by initially having only a portion of the heater connected to the power source.
