Wires - Galvanized for ACSR Conductor Centers

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.

This Wire is cold drawn and then covered with Zinc, achieving the customer’s desired properties.
