Anotace

This specification covers concentric-lay-stranded self-damping aluminum conductors, steel-reinforced, and its component wires for use as overhead electrical conductors. The tensile strength and elongation requirements of the round and trapezoidal wires shall be the same except for the shape and diameter tolerance. Joints shall not be made in the finished steel wires. The lay factor and direction are specified. The strength and electrical resistance of a complete conductor are calculated. Tests for mechanical and electrical properties of aluminum and steel core wires shall be made before stranding. Gap dimensions shall be measured during fabrication of the conductor.
