SPEC 55 Wire
SPEC 55 wire is insulated with modified radiation cross-linked ETFE
polymer. It is available as single-wall or as a dual-wall construction
when used as an airframe wire. Chosen for its balance of properties,
SPEC 55 wire has outstanding resistance to chemicals and solvents,
electrical arc track resistance and is not susceptible to UV and
moisture degradation.
SPEC 55 wire is lightweight and can be used
continuously at temperatures up to 200ºC and as such is widely used
on aircraft, satellites and in formula one autosport harness systems.
