TREFINASA was founded in 1999 with the initial goal of producing Aluminum Clad Steel wire (ACS) through the continuous extrusion process. This wire is generally used in the electrical industry, more specifically in the manufacture of fiber optic cable (OPGW) and cores for ACSR electrical conductors intended for distribution and transmission overhead power lines.
TREFINASA, using as a manufacturing technique the same continuous extrusion system used for ACS wire, expanded its catalog to extruded aluminum products:
- Aluminum tube
- Aluminum tube containing fiber optics for OPGW cables
- Flat, round and other forms of aluminium profiles
These products are used in the automotive, refrigeration and household appliance industries, as well as components for cable and insulated and enameled conductor.
In 2006, TREFINASA began manufacturing low sag conductors. These special conductors allow to increase the electric current transmission capacity with respect to the capacity of equivalent conventional conductors, maintaining the regulatory ground distances.
In 2016, after many years present in the electricity market and based on its extensive experience in HTLS conductors, TREFINASA started to manufacture standard Electric Conductors for overhead lines.
Finally, in 2018 TREFINASA acquired the rights to the MADE hardware brand by adding to its catalog hardware for overhead power lines, a complementary product to the conductors already offered.
TREFINASA’s quality system is endorsed with ISO-9001, IATF-16949, ISO-14001 and ISO-45001 certificates.
TREFINASA products have the AENOR product certification according to the specific regulations applicable in each case.
