Constructed of industrial grade16 AWG buss wire with a tinned copper braidand optional overjacketing, SRL ensures operatingintegrity in Div. 2 hazardous environmentsas well as certain corrosive industrialenvironments. SRL heating cablehas a maximum maintenance temperaturerating of 150°F (65°C).Features• Energy effi cient, self-regulating SRL usesless energy when less heat is required.• Easy to install, SRL can be cut to any length(up to max. circuit length) in the fi eld.• Field splices can be performed easily in minuteswith no scrap or wasted cold sections.• SRL features lower installed cost than steamtracing, less maintenance expense and lessdowntime.• SRL can be overlapped without burnout,which simplifi es heat tracing of in-line processequipment such as valves, elbows andpumps.• Because SRL is self-regulating, over-temperatureconditions are minimized.• Chromalox termination, splice, tee and endseal kits reduce installation time.ConstructionABCDCut to Lengthin FieldCan be SingleOverlappedTwin 16 AWG Copper Buss Wires —Provide reliable electrical currentcapability.Semiconductive Polymer Core Matrix —“Self-Regulating” component of the cable,its electrical resistance varies withtemperature. As process temperaturedrops, the core’s heat output increases; asprocess temperature rises, the heatoutput decreases.Polyolefi n Jacket — Flame retardant,electrically insulates the matrix and busswires and provides resistance to waterand some inorganic chemical solutions.Tinned Copper Braid — Providesadditional mechanical protection in anyenvironment and a positive ground path.Maintains up to150°FWithstands up to185°FLow TemperatureETemperatureSelf RegulatingOutputHigh Temperature Fluoropolymer or TPROverjacket (optional) — Corrosionresistant, fl ame retardant overjacket ishighly effective in many environments.TPR coatings protect against certaininorganic chemical solutions.Fluoropolymer coatings are used forexposure to organic or corrosivesolutions.
