TE 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 TE Connectivity products are chemical-resistant and used on high-temperature hookup wire applications. Spec-55 is also not susceptible to UV and moisture damage.
Single Wall
The following single wall constructions are available for Spec 55 Wire:
- 0.10 [.004]. The TE part number schema for these are 55/03XX 4 mil
- 0.15 [.006] (6mil wall thickness)
- These thicknesses are ideal for use inside black boxes.
Dual Wall
The following dual-wall constructions are available:
- .25 [.010]. The TE part number schema for these are 55A08XX 10 mil
- 0.2 [.008]. The TE part number schema for these are 55A02XX 8 mil
Spec-55 wire includes a contrasting core color acting as a damage indicator. Balancing properties make this wire ideal for resistance to chemical and solvents, and impeccable electrical arc rack resistance. Spec-55 is available in twisted pairs, triples, and can be made into shielded and jacketed cables. The 55PC portion of this spec is unique as it adheres to the Boeing material standard BMS13-48 specification. Exceeds FAR 25 test requirements for flame resistance and smoke density while providing excellent flexibility-Spec 55 is the ideal wire to install for new aircraft and equipment maintenance!
