T/E Connectivity Spec 55A Wire

Spec 55A wire is insulated with a modified radiation cross-linked ETFE polymer. The dual wall construction is currently implemented on numerous aircraft programs. Available in single or dual wall constructions, the Spec 55 wire is small in size, lighter weight, and resistant to electrical arc tracking in wet or dry conditions. With temperature ranges of -65°C to 200°C, these T/E Connectivity products are chemical resistant and used on high-temperature hook up wire applications. Spec-55 is also not susceptible to UV and moisture degradable. +
