RX-C
Specifications
The Danfoss RX-C self-regulating heating cable provides a continuous drain path for melting
ice and snow to leave a roof through the gutters and into the down spouts. The power output
of the conductive core material increases or decreases in response to ambient temperature
changes and occurs at every point along the length of the cable. Two jackets, an inner jacket
bonded to the core and a thermoplastic elastomer insulation jacket provides excellent
dielectric strength and in combination with the over jacket provides excellent moisture
resistance and protection from impact and abrasion damage.
