An appliance is provided for terminating high temperature conductors. The appliance includes a clevis member, a first set of aluminum elongate helically formed reinforcement members, and first and second U-shaped dead-end members having leg portions formed of an aluminum material and an aluminum-coated metal material, respectively. The reinforcement members and first and second dead end members are applied to the associated conductor in a layered relationship in a manner to establish a phase ordering of aluminum alloy and aluminum covered steel wire materials over the circumference of the conductor. The combination of aluminum alloy and aluminum coated steel wire materials provides desired strength while maintaining an operating temperature of the appliance lower than an operating temperature of the associated conductor.
