This standard specifies the characteristics of protective products, commonly known as greases, for corrosion protection of bare overhead line conductors made of aluminium, aluminium alloy, steel wires or a combination of these wires.

Specifies the electrical and mechanical characteristics of concentric lay, overhead conductors of wires formed or shaped before, during or after stranding, made of combinations of any of the following metal wires: a) hard aluminium as per EN 60889 designated A1; b) hard aluminium as per EN 60889 designated A1F wire shaped before stranding; c) hard aluminium alloy as per EN 60104 designated A2 or A3; d) hard aluminium alloy as per EN 60104 designated A2F or A3F shaped before stranding; e) regular strength steel, designated S1A or S1B, where A and B are zinc coating classes, corresponding respectively to classes 1 and 2; f) high strength steel, designated S2A or S2B; g) extra high strength steel, designated S3A; h) aluminium clad steel, designated SA.

Provides informations with regards to conductors specified in IEC 61089. Such informations include properties of conductors and useful methods of calculations. It does not discuss all theories and available methods for calculating conductor properties, but provides users with simple methods that provide acceptable accuracies.[
]This publication has the status of a Technical Report - type 3.

Lays down the electrical resistivity, tensile strength and elongation of commercial annealed aluminium electrical conductor wire having a diameter greater than 1 mm (0.0394 in).

Is applicable to non-interrupted creep-testing of stranded conductors for overhead lines such as those specified by IEC 61089. Procedures for interpreting the results are also included. The object of the test is principally to calculate creep for any purpose and to compare creep of different conductors.

Prescribes the electrical properties of commercial-purity aluminium for busbars, regardless of the cross-sectional shape of the bar.

Specifies volume resistivity, tensile strength, 0.2 per cent proof stress and elongation after fracture for heat-treated aluminium alloy busbar material of the AI-Mg-Si type.[

Applies to hand-drawn aluminium wires for the manufacture of stranded conductors for overhead power transmission purposes. Specifies the mechanical and electrical properties of wires in the diameter rank 1.25 mm to 5.00 mm.

D113/067: TC 7 disbanded

Applies to bare, hard-drawn, round, aluminium-clad steel wires of different electrical and mechanical properties.

Applicable to thermal-resistant aluminium alloy wires before stranding for manufacture of stranded conductors for overhead lines. It specifies the mechanical, electrical and thermal resistant properties of wires in the diameter range commercially available.

This standard applies to round zinc-coated steel wires used in the construction and/or reinforcement of conductors for overhead power transmission purposes.
It is intended to cover all wires used in constructions where the individual wire diameters, including coating, are in the range of 1,25 mm to 5,50 mm.
Types of wire are designated STyz, where y represents the grade of steel and z represents the class of zinc coating.
To reflect the needs of conductor users, the only combinations of steel grade and zinc coating covered by this standard are ST1A, ST2B, ST3D, ST4A, ST5E and ST6C.
The properties specified are those before stranding.

Specifies the electrical and mechanical characteristics of round wire concentric lay overhead electrical stranded conductors.     Supersedes IEC 60207, 60208, 60209 and 60210.                   [
