Constructed of industrial grade16 AWG buss wire with a tinned copper braidand optional overjacketing, SRP ensuresoperating integrity most hostile industrialenvironments.Features• Energy effi cient, self-regulating SRP usesless energy when less heat is required.• Easy to install, SRP can be cut to any length(up to max circuit length) in the fi eld.• SRP features lower installed cost thansteam tracing, less maintenance expenseand less down time.• SRP can be single overlapped without burnout,which simplifi es heat tracing of in-lineprocess equipment such as valves, elbowsand pumps.• Because SRP is self-regulating, overtemperatureconditions are minimized.• Chromalox U-Series Connection Kits reduceinstallation time.ConstructionA Twin 16 AWG Copper Buss Wires – Providereliable electric current capability.B Semiconductive Polymer Core Matrix“Self-Regulating” component of thecable its electrical resistance varies withtemperature. As process temperaturedrops,the core’s heat output increases; asprocess temperature rises, the heat outputdecreases.C Fluoropolymer Jacket – Flame retardant,electrically insulates the matrix and busswires and provides corrosion resistance.D Tinned Copper Braid – Provides additionalmechanical protection in any environmentand a positive ground path.E High Temperature FluoropolymerOverjacket – Corrosion resistant, fl ameretardant overjacket is highly effectivein many environments. Protects againstexposure to organic or corrosive solutions.The overjacket also protects againstabrasion and impact damage.ApprovalsCSA Certifi edClass I, Division 2, Groups B, C, DClass II, Division 2, Groups F, GClass IIIFM ApprovedClass I, Division 2, Groups B, C, DClass II, Division 2, Groups F, GClass IIIUL Recognized ComponentAWM Style 20565Rated T485
