Aluminum is often selected for its electrical conductivity, which is nearly twice that of copper on an equivalent weight basis. The requirements of high conductivity and mechanical strength can be met by use of long-line, high-voltage, aluminum steel-cored reinforced transmis-sion cable. The thermal conductivity of aluminum alloys, about 50 to 60%

Three oxidation configurations were considered (Fig. 3). The initial oxide thickness was assumed to be 2.5 nm. The dimensions of aluminum core and alumina shell were assumed to change due to both oxidation and thermal expansion [14-17]. A change in aluminum density upon its melting was taken into account. For cases I and II, the
