M27500 specification provides for a wide range of construction options allowing for optimal performance in virtually any environment. Any number of design components are available for users to choose from — including conductor size, number of conductors, insulation type, shield material (or no shield), circuit identification, and single or double walled jacket. AS22759 wire has a fluoropolymer–insulation and single-conductor offering high performance and reliability in severe wind and moisture prone (SWAMP) zones such as engine nacelles and areas requiring overload stability, low smoke emission, and fire resistance such as aircraft cabins. Meeting the M27500 specifications.
SAE AS22759/41 is ideal for use in avionics because of its superior resistance to moisture, chemicals, solvents, smoke, and flame. A nickel-plated copper conductor and dual-layer cross-linked, extruded ETFE insulation also give this wire multi-purpose qualities for other commercial applications.
This M27500-18SM3N23 extruded XL-ETFE tefzelâ„¢ wire (Alternate Part# 18SM3N23) meets SAE AS22759/41 specifications and has three, 18 AWG nickel-plated copper conductors, and a dual layered irradiation, cross-linked, extruded ETFE jacketing.
