Wires - Covered with aluminum for ACSR/AS conductor centers
High mechanical resistance, good conductivity, excellent resistance against corrosion and compatibility with solid aluminum wires make the AS cables and wires a very attractive nucleus for ACSR (ACSR/AW) conductors.
When the AS are used as reinforcing agents, they combine their high mechanical resistance characteristics with those of better conductivity, thus improving the performance of the conductors.
AS wires and cables are available to all ACSR fabricators in order to be used as reinforcements for their conductors.
Uses of the AS cables as conductors for rural electrical grids
The AS aluminized steel cables have become an economic alternative in studies of selection for conductors that operate in systems that are characterized by low electricity charges and large mechanical demands, such as rural electrical grids.
The lesser cost of the AS cables compared with the conductors traditionally used minimizes the cost of the initial inversion.
The largest parameter (tension related to breaking load) of the AS cables compared with the ACSR represents a lesser number of structures in line.
The electrical conductivity of the AS cables is 20.33% IACS (The third part of an aluminum cable of the same diameter). In studies of conductor selection, it has been determined that the AS cables lie in the equilibrium point between their greater losses in comparison to all aluminum cables and their lesser cost. This is done by taking into account the cost of the project.
The AS cables (known as Aloweld in the United States), are widely used in the country and the rest of the world. They were originally developed as guard cables, searching for an economic conductor that would have a long useful life and a higher mechanical resistance. With the fabrication of these cables in Colombia, the void that existed in the national market was filled. This allowed national electrical enterprises to stop importing expensive cable that didn’t fit their exact needs.
Steel cables covered in aluminum for guard wire, messenger wire, or guy wire.

Steel Wires and Strands for ACSR type Conductor nucleuses
With the rapid development of electrical generator plants, the ACSR (Aluminum Conductor Steel Reinforced) presents itself as the perfect cable for the transmission of electricity. The galvanized strand for ACSR requires a great quality due to the fact that they constitute the support for aluminum conductors across great distances.
