Application
The covered aluminum steel wire for compression, internationally known as Alumoweld or ACS, is a wire of high resistance whose cover is carried through an extrusion process, that adheres the aluminum by pressure and heat. Once the covering process is finished, the wire is drawn until its final diameter without any alteration in the aluminum steel ratio.
Manufacture of Overhead Bare Conductor, OPGW, Ground Wire,Overhead Ground wire, Messenger wire, Guy wire, Formed wire for protecting, Terminating and Splicing Transmission and Distribution lines,Shield wire Protecting Transmission lines against lightning damage fence, barber wire and hardware. Aluminum-Clad steel Wire and Strand is used by Power Utilities as well as Formed Wire and Optical Ground Wire Manufacturers.
