Sets out requirements and tests necessary for homogeneous bare electrical conductors for overhead power transmission and constructed of all aluminium and aluminium alloy wires. A range of wire sizes, 2.50mm to 4.75mm, and their properties are provided.

This Standard specifies requirements and tests for homogeneous bare electrical conductors for overhead power transmission, and constructed of all aluminium or all aluminium alloy wires.NOTES:1 Appendix A gives methods to calculate conductor properties.2 Appendix B gives the coefficient of linear expansion and the theoretical basis for the calculation of modulus of elasticity.3 Appendix C lists code names which may be used to refer to specific type and construction of conductor.4 Appendix D lists information which should be supplied with enquiries and orders for conductors.
