Spec 55
Wire and cable
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 cutthrough characteristics.
The dual wall airframe construction of
Spec 55 wire is currently used on
numerous aircraft programmes. It has
a 0.25 mm total wall thickness and 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.

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
thicknesses. The dual wall airframe wire
has an insulation wall thickness of
0.25 mm for robustness in unprotected
harnesses and has excellent wire to
wire abrasion properties. The
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.Temperature rating
Spec 55 wire and cable is rated for
continuous operation from -65°C to
+200°C and for short periods at
temperatures as high as 400°C.
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 reistance.
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.

r u l e hemical resistance
pec 55 is unaffected by all commonly
sed chemicals, eg. fuels, hydraulic
luids, defluxing agents, cleaners,
oolants and de-icers. It also shows
xcellent resistance to weathering

oth ESA and NASA requirements for
utgassing.
lammability
pecial additives increase the flame
etardance of Spec 55 compared to
nirradiated ETFE so that it meets the
atest high performance tests,

Electrical arc tracking resistance
Spec 55 insulation demonstrates a total
resistance to arc tracking under both
wet and dry conditions at aircraft
system voltages.
