m o .c U 4 t e e h S a at .D w w w Spec 55 wire is insulated with modified radiation cross-linked ETFE polymer. It has a temperature rating of -65°C to 200°C continuous, and combines the easy handling of a flexible wire with excellent scrape abrasion and cut-through characteristics.

It has a choice of two total wall thickness, 0.25 mm and 0.2mm, both have a contrasting core colour to act as a damage indicator. Chosen for its balance of properties, Spec 55 wire has outstanding resistance to chemicals and solvents, excellent electrical arc track resistance, and is not susceptible to UV and moisture degradation. Single wall equipment wire constructions are available in 0.10 mm and 0.15 mm wall thicknesses for use inside black boxes where flexibility and solder-iron resistance make it a wire which is very easy to reliably install. Both single and dual wall insulated wires are available in twisted pairs, triples, etc., and as screened and jacketed cables. Spec 55 Insulation system - Dual wall Insulations Radiation Crosslinked, Modified ETFE Innerlayer coloured blue m o .c U 4 t e e h S a at .D w w w Spec 55 Physical characteristics Size and weight Spec 55 wire provides one of the most comprehensive wiring product ranges for aerospace users, with a wide choice of conductor sizes and insulation wall thickness. The dual wall airframe wire has an insulation wall thickness of either 0.2mm or 0.25 mm for robustness in unprotected harnesses and has excellent wire to wire abrasion properties. The single wall equipment wire has a 0.15 mm wall thickness for use inside equipment and protected harnesses. For high density interconnect wiring, the 450 volt 55M041X series of equipment wire has a nominal 0.1 mm wall and provides considerable weight and size savings over other comparable wires. Handling The excellent flexibility and low resilience makes Spec 55 the ideal wire to install, both in new aircraft and equipment and for maintenance purposes. The wire is easily stripped with conventional tooling. The insulation is readily marked by hot stamp, ink jet or laser, and can be potted without preetching. For full descriptions of the appropriate tools see separate wire handling guide.

Mechanical performance Radiation crosslinking of the Spec 55 insulation significantly improves the following mechanical characteristics; scrape (sharp edges), cross wire abrasion, cut-through resistance and creep resistance. Solder iron/Overload resistance Radiation crosslinking ensures that the insulation does not melt at high temperature. As a result Spec 55 wire is resistant to hot solder irons and current overloads which would melt most thermoplastic insulations. Chemical resistance Spec 55 is unaffected by all commonly used chemicals, eg. fuels, hydraulic fluids, defluxing agents, cleaners, coolants and de-icers. It also shows excellent resistance to weathering (UV, ozone, pollutants, water). Space wire Spec 55 is available in special versions suitable for use in outer space meeting both ESA and NASA requirements for outgassing. Flammability Special additives increase the flame retardance of Spec 55 compared to unirradiated ETFE so t.
