Stranded tinned copper conductor, extruded irradiation cross-linked Polyalkene insulation with irradiated cross-linked Polyvinylidene Flouride (PVDF) insulation jacket (conductors per SAE-AS81044). Two conductors twisted to form a pair. Four pairs cabled with one single conductor, optional binder tape, overall optimized tinned copper braid shield, optional binder tape, cross-linked Polyolefin jacket, surface marking. Special Identification Code per Mil Spec M24640/25 Table II. Multipair, 7 strand coated or uncoated copper conductor, composite tape wrapped insulation consisting of mica-glass, Polymide tape and Polymide-FEP tape with Polyimide coating. Two conductors twisted to form a pair, (Type 11/2 is three conductors to form a triad.) The required number of pairs cabled consecutively, optional binder tape, cross-linked Polyolefin jacket, surface marking. TTXOW: Same construction as TTXW with overall optimized tinned copper braid shield and optional binder tape. Telephone Identification Code by Method 3 or 6. Pair Identification Code by Method 6 (black/white conductor except Type -11/2 use black/white/red).
