3 Every Olex cable is subject to exacting quality control procedures, ensuring rigid testing to relevant standards at every stage of extensive range of Olex bare overhead conductors includes internationally accepted conductor configurations. All-aluminium, contemporary aluminium alloy and steel-reinforced conductor designs are manufactured to Australian Standards and specific customer requirements, including most international , mechanical and cost considerations determine the selection of a conductor for a particular application.

4 The values of resistance, inductance and, where applicable, capacitance, should be such that voltage regulation, temperature rise and losses will be within acceptable limits when the conductor is carrying the required current load. On high voltage lines, radio interference characteristics or corona losses often dictate the minimum diameters which may be used. Conductor design and span lengths are also determined by AERIAL mechanical loads likely to be imposed by wind or ice, as well as by economic catalogue presents the standard range of Olex overhead conductors and cables.

5 Information on other power and industrial cable products is available from the Olex Office in your state or provides additional protection against corrosion. Conductors incorporating aluminium-clad steel are more corrosion-resistant than those incorporating galvanised steel. Aluminium alloy 1120 conductors are becoming more popular as replacements for steel-reinforced conductors in areas of high corrosion exposed surface of aluminium wires can be specially treated to provide a dull, non-specular finish when conductors are required to blend into the environment.

6 Aluminium alloy 1120 conductors may be identified by means of a blue thread incorporated within the lengths are determined from a consideration of such factors as physical drum dimensions, drum weights, span length and handling offers a number of materials meeting the requirements of both Australian and International Standards. Aluminium 1350 High purity electrical conductor (EC) grade aluminium (alloy 1350) has a conductivity of 61% IACS and UTS of 160 alloy 1120 Olex alloy 1120 has a conductivity of 59% IACS and UTS of 240 250 MPa and 40 50% higher strength than a similar conductor of EC grade material.

7 This alloy can be considered a high tech version of EC grade aluminium and offers significant advantages over older type alloys, such as alloy 6201. Steel-reinforced aluminium alloy 1120 conductors have a high strength to weight ratio, resulting in small sags on long span lengths. Fittings for alloy 1120 conductors are similar to those used for EC grade aluminium note that Olex no longer offers alloy 6201 conductors, as they have little, if any, practical advantage over alloy 1120. Compared with alloy 1120, alloy 6201 conductors have poor electrical performance, are less resistant to corrosion, more susceptible to fatigue failure.

8 More expensive and require the use of special Hard drawn copper wire produced from high conductivity alloy 110A has a conductivity of 97% IACS and UTS of 405 steel Galvanised steel wire made from fully-killed steel with a carbon content of has a UTS of It is galvanised by either a hot dip or electrolytic process to give a zinc coating mass of 200 260 steel Aluminium-clad steel has an aluminium cladding with a radial thickness not less than 5% of the overall wire diameter. It has a conductivity of IACS and UTS of Conductors incorporating aluminium-clad steel for reinforcement have lower electrical resistance and provide better protection against corrosion than those using galvanised wires in all bare conductors are stranded concentrically with successive layers having an opposite direction of lay, the outermost layer being right-handed.

9 When required, a larger central wire (king-wire) is included in a conductor. The diameter of this wire is based on conductor design considerations and is usually 5% greater than the surrounding wires. The incorporation of a king wire is often an advantage for ACSR type conductors, as it ensures that the surrounding layer of wires fits firmly on the central conductors may be subjected to corrosive conditions such as high pollution found in industrial areas or salt spray in coastal areas.
