Abstract
A lightweight composite electrical wire having a fusible alkali core encased or enclosed by a wall, and further including a plurality of transverse bulkheads that separate the core into a plurality of sections. In embodiments the core is sodium, and the wall is aluminum. The transverse bulkheads separate the core longitudinally, precluding or mitigating any loss of core material in accident scenarios, and may include visual and/or tactile indicators to facilitate identifying locations for cutting and connecting the conductor. A insulative outer layer may also provided. In an embodiment the fusible alkali core comprises a plurality of parallel elements separated laterally by wall material and longitudinally by the bulkheads. At least a portion of the bulkheads may be formed from a material having a melting temperature higher than the maximum normal operating temperature of the wire, but lower than the boiling point of the alkali core.
