Applications
SPEC 55 wire is insulated
with modified radiation
cross-linked ETFE polymer.
It has a temperaturerating
of -65°C to 200°C [-85°F to
392°F] continuous using a
silver plated copper con-
ductor,and combines the
easy handling of a flexible
wire with excellent scrape
abrasion and cut-through
characteristics.
The dual wall airframe con-
struction of SPEC 55 wireis
currently used on numerous
aircraft programs. It has a
choice of two total wall
thicknesses, 0.25 [.010]
(55A08XX 10 mil) and 0.2
[.008] (55A02XX 8 mil).
Both have a contrasting
core color to act as a dam-
age indicator. Chosen for its
balance of properties,
SPEC 55 wire has outstand-
ing resistance to chemicals
and solvents, excellent
electrical arc track resist-
ance, and is not susceptible
to UV and moisturedegra-
dation. Single wall equip-
ment wire constructions
are available in 0.10 [.004]
(55/03XX 4 mil) and 0.15
[.006] (6 mil) wall thicknesses
for use inside black boxes
where flexibility and solder-
iron resistance make it a
wirewhich is veryeasy to
install reliably.
Both single and dual wall
insulated wires are available
in twisted pairs, triples, etc.,
and as shielded and jacket-
ed cables.
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
thicknesses.The dual wall
airframe wire has an insula-
tion wall thickness of either
0.2 [.008] or 0.25 [.010] for
robustness in unprotected
harnesses and has excel-
lent wire to wire abrasion
properties.
The single wall equipment
wirehas a 0.15 [.006] wall
thickness for use inside
equipment and protected
harnesses. For high density,
interconnect wiring, the 450
volt 55M041X series of
equipment wirehas a nomi-
nal 0.1 [.004] wall and pro-
vides considerable weight
and size savings over other
comparable wires.
Handling
The excellent flexibility
and handleability 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
pre-etching.
SPEC 55PC Wire and Cable
Insulation System
This product was originally
developed to meet Boeing’s
material standard BMS13-
48 for the 777 airliner.
SPEC 55PC provides light-
weight, compact insulation
that matches the proven
performance of our
SPEC 55 wire. Today, 55PC
is specified and utilized on
the majority of aerospace
platforms worldwide.
Tyco Electronics’ rigorous,
statistical-process-con-
trolled manufacturing has
produced Raychem wiring
that is rugged and versatile
enough for a wide range of
commercial and defense
aerospace applications,
including electronic hook-
ups in harsh, open airframe
environments.
SPEC 55PC wire and cable
systems featurean 8-mil air-
frame wire that is lighter and
smaller than typical 10-mil
wire, with little reduction in
key mechanical perform-
ance features. SPEC 55PC
wireoffers flame resistance
superior to FAA standards
and also resists scrape
abrasion, notch, propaga-
tion, cut-through, and
electrical arc tracking.
nMeets Boeing material
standard BMS 13-48.
nExceeds FAR 25 test
requirements for flame
resistance and smoke
density.

Environmental Performance Temperature Rating
SPEC 55 wire and cable is
rated for continuous opera-
tion from -65°C to +200°C
[-85°F to +392°F] and for
short periods at tempera-
tures as high as 400°C
[752°F].
Mechanical Performance
Radiation crosslinking of the
SPEC 55 insulation signifi-
cantly improves the follow-
ing mechanical character-
istics; scrape (sharp
edges), cross wire abrasion,
cut-through resistance and
creep resistance.
Solder Iron/Overload
Resistance
Radiation crosslinking
ensures that the insulation
resists melting at high
temperatures. As a result
SPEC 55 wireis 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 unir-
radiated ETFE so that it
meets the latest high per-
formance tests, eg. BS
3G230 vertical test FAR 25.
Electrical Arc Tracking
Resistance
SPEC 55 insulation demon-
strates resistance to arc
tracking under both wet
and dry conditions at air-
craft system voltages.
Conductor Primary Wire Twisted Pair Shielded & Jacketed
Single Pair
55PC - Extra Light Weight Constructions
For applications where weight is critical, light weight tight tolerance conductors and insulations are available. These
are manufactured using statistical process control methods and achieve weights that are equal or lighter than the
equivalent polyimide/PTFE constructions.
