Aluminium Clad Steel wire - Extruded Aluminium Tube - Extruded Aluminium Flat wire - Overhead conductor - Fittings and accessories

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.

PRODUCTS

Aluminium Clad Steel Wire (ACS)

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.

Aluminium tube for refrigeration

Aluminium tube is produced by means of continuous extrusion in different aluminium alloys.

Alloys;

  • Pure aluminium alloys 1235 / 1060 / 1370.
  • Aluminium alloys 3000 series (AW 3003 / 3103).

Properties of the different products are as follows;

  • Dimensions:
    • Wall thickness >= 0.40 mm.
    • Outer diameter between 2 mm and 30 mm.
  • Diameter tolerances:
    • Direct extruded tube: ± 0.04 mm.
    • Extruded + drawn/calibrated tube: ±0.02 mm.
  • Tensile Strength:
    • Direct extruded tube >= 60 MPa.
    • Extruded + drawn/calibrated tube >= 80 MPa.

Aluminium Profile

Different shapes and alloys according to customer requirements.

Aluminium Flat Wire

Mainly for electrical use.

PRODUCTION

Aluminium Products are manufactured by continuous extrusion machines.

Actual production capacity for tube and aluminium profiles is 1000 Ton/year.

Capacity will grow according to market development and necessities.

QUALITY CONTROL

Aluminium Products surface quality is controlled using an on-line Eddy Current equipment during all the manufacturing process. Finally, tube’s sealing is guaranteed by means of nitrogen  pressurization.

TREFINASA has arranged a Factory Laboratory with modern testing equipment for analyzing the product in all fabrication stages. These results are fully included in the quality report to guarantee customer specifications and requisites.

Quality System is according to ISO-9001 Standard.
