Extreme Conduits Withstand Extreme Temps


A complete line of liquidtight flexible electrical conduits are designed for extreme temperature applications and feature specially formulated jackets that withstand excessively hot or cold conditions, providing wiring solutions where standard liquidtight conduits would not be suitable.  Applications include chemical production, offshore drilling platforms, steel production, wind turbines, wireless communications towers, weather stations, aerospace, and defense stations, all which can experience temperatures ranging from -40o to more than 120oF.


Electri-Flex offers five types of jacketed metallic flexible extreme temperature conduit. Type AT is non-UL with temperature ranges from -55° to +105°C, with short-term spikes to +120°C. Type ATLA is both UL listed and CSA approved, sunlight resistant and accommodates temperatures of -55° to +105°C dry, 60°C wet, and 70°C in oil. Type ATX has a thermoplastic rubber jacket that is virtually unaffected by temperature extremes and is rated for low-smoke zero halogen (LSZH) conditions. Temperature range is -60° to +150°C with spikes to +165°C. EMI/RFI shielding conduit, Types EMS and EMCS, are specified for operation between -55o and 105oC.


Non-metallic flexible conduit offerings include Types NMHT, LNMP and Corrlok. Type NMHT is UL and CSA approved with temperature ranges of -20° to +105°C dry, 60°C wet, and 70°C in oil. Type LNMP is UL and cUL approved and is well suited for continuous flexing situations and does not contain a metal core that could fatigue from repeated flexing or vibration. The PVC is flame-retardant and resists oils, mild acids, and exposure to sunlight with temperature ranges of -55° to +105°C. The Corrlok system is a family (Types CL, CLR, and CLFR) of lightweight flexible raceway alternatives that withstands harsh environments and is made from specially-formulated Nylon that is non-toxic and self-extinguishing, making it well suited for confined areas where fire can be a concern. It is LSZH rated, flame resistant, has high impact and crush strength, and is resistant to many chemicals and sunlight, with temperatures of -40° to 105° C with spikes to 150°C.
