Barre Omnibus En Aluminium De Qualité Électrique

La barre omnibus en aluminium de qualité électrique est également appelée barre omnibus en aluminium de qualité CE, a normalement deux types, l'un est en aluminium pur, tel que l'alliage 1350, 1050, 1060 et 1070, l'aluminium pur a une conductivité d'environ 65% IACS. L'autre est un alliage 6 ***, comme les alliages 6061 et 6101, l'alliage 6101 est assez courant pour l'utilisation du jeu de barres.

Application de l'alliage 6101 dans la barre omnibus

Aluminum is subjected to oxidisation when exposed to the atmosphere. The coating of aluminum by different metals is one of the most comon commercial practices used to improve the stablity and to suppress the galvanic corrosion of aluminum-to -copper connection. The most widely used coating materials are tin, silver, copper, cadmium and nickel.

Physical and Electrical Properties of Aluminum Wrought Bus Conductor Alloys
(ASTM B 236,B 317,and The Aluminum Association)

Applying to all alloys and tempers of wrought alloys, typical values. Weight, lb/cu in. (rounded) 0.098 Specific heat, cal/gm/℃ or BTU/LB/F 0.214 at 70℃ for 1350 and 0.220 for 6101(e). Coefficient of thermat expansion (linear)/℃ 0.000023. Specific gravity - 2.70.				Modulus of Elasticity, Typical, psi 10 * 106, up to 2% higher in compression. Note : if two values are shown, the more favorable is “typical”; the less favorable is designated “minimum” provided a higher value is favorable. Otherwise the term “guaranteed” is sometimes used.

(a) For alloys not shown. obtain conductivities from Table 13·2, and interpolate from the listed values.
(b) Per note on Table 1;3.2, 55% conductivity is much used as design basis for 6063·T6 alloys for tubes, hence coefficients should be taken from the column, headed 55%.
