■ Small size, light weight
■ Resistant to most chemicals
and electrical arc tracking

Applications
SPEC 44 wire has a dual
wall construction which
combines the outstanding
physical and electrical
characteristics of radiation
crosslinked polyalkene with
the excellent mechanical
and chemical properties of
radiation cross-linked
polyvinylidene fluoride
(PVDF).
The result is a wire insulation system that offers a
150°C [302°F] temperature
rating, small size, light
weight, solder iron resistance, and resistance to
most solvents, fuels and
lubricants.
SPEC 44 wire and cable is
highly flame retardant, nonmelting, does not cold flow,
and though mechanically
very tough, is easy to handle and install using conventional tools.
Originally developed for
aerospace and military
requirements in applications of high density and
complex circuitry, SPEC 44
wire and cable now finds
wide use throughout industry, in commercial and
military electronics,
avionics, on satellites,
aircraft, helicopters, ships,
trains, military ground
systems, and offshore platforms where environmental
conditions demand consistently reliable performance.
In airframe applications
SPEC 44 constructions can
offer a modern dimensional
replacement for PVC/Nylon/
Glass braid type wire and
cables. SPEC 44 wire is
offered in a wide range of
sizes in stranded conductors, standard materials
available being tin or
silver-plated copper and
high strength copper alloy.
Voltage ratings of 600, 1000
and 2500 volts are available
as standard. Shielded and
jacketed versions include
single and multi-conductor
constructions and flat braid
shields where further size
and weight savings are
achieved.

SPEC 44 (Continued)
Physical Characteristics
Small Size
General Handling
Lengths
SPEC 44 equipment wire,
600 volt rated has a 0.19
[.008] nominal wall thickness compared to 0.25
[.010] and 0.38 [.015] for
equivalent PTFE and PVC
wires in MIL-DTL-16878,
SAE AS22759 or BS 3G210.
The flexibility of SPEC 44
and the ease with which it
takes a 'set' makes it one of
the easiest of the 'high
performance' wires to
install. Stripping is done
with conventional die blade
strippers.
SPEC 44 is available in long
continuous lengths and can
be supplied for use on automatic cut and strip wire
preparation machines.
Light Weight
The tin-plated conductor
usually specified is easily
soldered or crimped. The
insulation may be easily
printed and does not need
etching before potting.
Because of the thin wall and
low density of the insulation
materials considerable
weight savings are made
over similarly rated PTFE
wires, eg:- 44A0111-22AWG
equipment wire 4.45
grams/meter max
