29542 Datasheet, PDF (1/4 Pages) Tyco Electronics – Dual wall construction

• Dual wall construction
• 600, 1000 and 2500 voltage rating
• Small size, light weight
• Low smoke and low corrosive
gas generation
• Resistant to most chemicals
and electrical arc tracking
Spec 44
Wire and cable
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 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, non-melting, 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, 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.
