Russia standard ACSR gost 839-1980 conductor Overhead Bare ACSR cables 132kv transmission line in rural area

Application:

Bare aluminum conductors, especially in the form of Aluminum Conductors Steel Reinforced(ACSR), have been widely used for overhead transmission lines as the most cost-effective and dependable product. As the name implies, ACSR is a concentrically stranded conductor composed of one or more layers of hard-drawn EC grade aluminum wires over a high strength coated steel core. The core may be single wire or stranded, depending on the size. Because of the numerous stranding combinations of aluminum and steel wires that may be used, it is possible to vary the portions of aluminum and steel so as to obtain the most suitable relation between current carrying capacity and mechanical strength for each application. For instance, a conductor having a small proportion of steel may be most economical for a wood pole line to transmit a large block of power whereas a conductor with a very large proportion of steel would be required for a long span crossing over water.  Between these two extremes are the conductors with normal proportions of aluminum and steel generally used for the more conventional transmission and distribution lines.

Anti-corrosion A.C.S.R.
Anti-corrosion ACSR is used in the corrosive areas like coastal areas or industrial zones. This ACSR is filled with anti-corrosive grease applied on the gaps between stranded wires and their external surfaces. Generally, anti-corrosion ACSR is divided into three types according to the method of greases coating :

Light Anti-corrosion Type : Only steel wires are coated
Medium Anti-corrosion Type : All the inner layers are coated
Heavy Anti-corrosion Type : All the inner and outer layers are coated
