LBTV

R LBTV Self-regulating heating cables Electrical freeze protection for long pipelines in both nonhazardous and hazardous (classified) locations The LBTV self-regulating heating cables provide freeze protection and low-temperature maintenance for longline applications. The LBTV heating cables maintain process temperatures up to 150°F (65°C) and can withstand intermittent exposure to temperatures up to 185°F (85°C). Heating cable construction Fluoropolymer outer jacket (-CT) Tinned-copper braid Modified polyolefin inner jacket Self-regulating conductive core Nickel-plated copper bus wire (10 AWG) The cables are configured for use in nonhazardous and hazardous (classified) locations, including areas where corrosives may be present. The LBTV heating cables provide long circuit length capability. They can be used for continuous circuit lengths up to 1125 feet powered from a single source. LBTV cables are especially well suited for tracing long pipelines containing temperature-sensitive fluids or where high reliability is required. Raychem® LBTV cables meet the requirements of the U.S. National Electrical Code and the Canadian Electrical Code.
