Self-Regulating Parallel Circuit Heating Cable

Self-regulating heating cable is a parallel circuit electric heater strip. The heat cable has an irradiation cross-linked conductive core of polymer material, extruded over the multi-stranded, tin plated, 18 gauge copper bus wires. The core material is conductive and increases or decreases its heat output in response to changes in temperature. The inner jacket is modified polyolefin and is extruded over and bonded to the core material.. A Al-Mg Alloy braid is installed over the second jacket to provide a continuous ground path. The final protective polyolefin outer jacket is added to make the heating cable suitable for wet applications, and protects the cable in installations where abuse is present.

The parallel bus wires apply voltage over the entire length of the self regulating heating cable, and the conductive core provides an infinite number of parallel conductive paths, permitting the installer the ability to cut the heat cable to any length needed, in the field. Because of the heating cable structural design, cutting will not create any dead spots or cold zones in the heat cable run. The heat cable can be overlapped without creating any hot spots or burnout, due to its self regulating characteristics.

self regulating heating cable is ideal for use in fluid flow under low temperature conditions. Typical applications of the heating cable are freeze protection and low watt density process temperature systems such as product pipelines, fire protection, process water, dust suppression systems, hot water and structural deicing applications.
