Specification 44

The Spec 44 cable features a double-wall insulation that combines the exceptional physical and electrical properties of radiation cross-linked polyalkenes with the superior mechanical and chemical properties of radiation cross-linked polyvinylidene fluoride (PVDF). The result is a cable insulation system that provides a temperature range up to 150 °C, small diameter, low weight, soldering iron resistance, and resistance to most solvents, fuels, and lubricants. The Spec 44 cables and wires are highly flame-retardant, non-melting, and cold-flow resistant. They are mechanically very robust, easy to handle, and easily processed with conventional tools. Spec 44 cables were originally designed for aerospace and military applications as well as for complex high-density wiring harnesses. Today, these cables and wires are widely used across the industry: in commercial and military electronics, avionics, satellites, aircraft, helicopters, trains, ships, and offshore drilling rigs, where highest resistance and reliability are required due to harsh environmental conditions. In aircraft wiring, Spec 44 constructions offer modern replacement solutions for PVC/nylon wires and cables with glass braid protective sleeves. Spec 44 cables are offered in a wide range of sizes — both as stranded and solid conductors — with standard versions made of tinned and silver-plated copper or high-strength copper alloys. Standard nominal voltages are 600 V, 1000 V, and 2500 V. Shielded and jacketed versions include single or multi-core constructions with flat wire shields for weight and outer diameter reduction.
