BMS 13-60 is a logical choice when high temperatures are required exceeding 200°C on Boeing commercial aircraft. With a maximum operating potential of 600 VRMs, this specification establishes the construction and performance requirements for different types of arc-resistant wire and cable that covers four categories: six mils, eight mils, 10 mils, and 19 mils nominal insulation thickness and is similar to the MIL-W-22759/80 and SAE-AS22759/80 constructions.
The temperature rating for each type is determined on the conductor or shield coating:
(1) 260°C rated wire has a nickel-coated copper conductor
(2) 260°C rated cable has a nickel-coated copper conductor and nickel-coated shield
(3) 175°C rated wire has an aluminum conductor
(4) 150°C rated wire has a tin-coated copper conductor
(5) 150°C rated cable has a tin-coated shield.
The construction of the wire is determined by the wire or cable type, class, and gauge size. With 56 types and 10 classes, the specifications cover sizes 26 AWG through 4/0 AWG. When completed, all cable types use white PTFE tape for the outer wrap of the cable jacket unless a different color is specified.
