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.
FUNDED PROJECTS
ENSURING QUALITY IN STEEL-MAKING PROCESSES THROUGH THE COOPERATIVE PREDICTIVE MAINTENANCE OF THE NDT INSPECTION ROTARY EQUIPMENT. RTC-2016-2749-7
1. The SMARTROT project aims to ensure the predictive detection ol failures in eddy current rotary inspection equipment, as well as their high maintenance, so that possible equipment failures can be anticipated and repaired before unforeseen interruptions occur as a result of them, or so that abnormal operating conditions that could be affecting the quality analysis can be detected.
The main aim of the project is to design, develop and validate a rotary inspection equipment that integrates a remote predictive maintenance system for this specific application and that enables the automatic generation of failure warnings via cooperative learning based on multiple cases.
The SMARTROT project (RTC-2016-4729-7) has funding totalling €472,759.20 (91.11% of the approved budget) from the European Regional Development Fund via the 2016 COLLABORATION CHALLENGES programme of the Ministry of Economy, Industry and Competitiveness, and within the themed objective of Promoting technological development, Innovation and quality research.
