Aluminium clad steel wire - Aluminium tube and aluminium wire manufacturers - HTLS and GAP overhead conductor - Alumoweld wire manufacturers
TREFINASA is a company stablished in 1999 with the first objective of manufacturing aluminium clad steel (ACS) wire. These wires are used in electrical industry, more concretely in manufacturing optical ground wire (OPGW) and strands for conductors installed in overhead electrical lines. Trefinasa, by applying the same manufacturing process, manufactures aluminium tubes with optical fibre inside for OPGW conductors, as well as extruded Aluminium profiles for insulated cables, extruded Aluminium flat wires for the automotive, electrical and renewable industries and extruded and/or calibrated Aluminium tubes for refrigeration, home appliances, automotive industry and rivets). Since 2018 and once the acquisition of the rights for MADE HERRAJES was completed, TREFINASA offers a complete solution including in its range of products the fittings for insulator string, bolted and compression clamps and accessories up to 500kV OHL. Trefinasa supplies to the most relevant European OPGW and ACSR manufactures, as well as to different electrical companies and appliance companies.
HTLS GAP Conductor - ACS and Alumoweld Wire
TREFINASA deployed in 2006 the manufacturing GAP type technology for High Temperature Low Sag conductors. These conductors are able to dispatch higher power and to reduce joule losses at standard operating temperatures, keeping the same safety clearances than their equivalent hard drawn aluminium conductor due to the possibility to continuously run at much higher operation temperature. Nowadays TREFINASA is developing the ACSS type technology for High Temperature Low Sag conductors to complete the wide range of available products for the upgrade of existing OHL at a very beneficial investment-cost ratio.
HISTORY
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.
