  • Gecsa manufactures flexible connections in copper and aluminum, where a flexible conductor is necessary when any of the elements to be joined is in motion or you want to avoid the transmission of vibrations to equipment of greater delicacy.

    Thanks to the wide range of products with which Gecsa works, flexible conductive parts are obtained for a multitude of applications and for a wide variety of needs in terms of form, flexibility, material or working conditions.

    The fields of application of our flexible connections can be in environments of high voltage or in conditions of high temperatures. Therefore, all flexible connections can be protected in various types of finish: heat shrink sleeves, fiberglass covers …

    Gecsa manufactures all kinds of flexible connections; copper or aluminum; of band, cable or braid, tinned, silvered or without any coating. From 5 mm2 of net section onwards, without size limit.

    We have bands from 0.2mm thick to 1mm.

    The most common applications are the following:

    • To avoid vibration effects.
    • For moving parts of welding machines.
    • Connections between low voltage terminals of transformers and busbars.
    • Connections in ferroalloy furnaces.
    • Earth connections.
    • Assembly of fixed and mobile conductor elements.

    The types of flexible connections that we produce are of two types: in sheet and in braid.

    GECSA designs and manufacture traditional and modern power conducting arms made of copper/steel or aluminum....

  • The current conducting arms designed and manufactured by GECSA offer a rigid and compact structure that adapts to the required demands on power and productivity in modern electric arc furnaces to allow rapid acceleration, vibration-free speeds in electrode movements and a high-level Insulation to work with high secondary voltages.

    Working with minimal production costs, maintenance stops and repairs due to the current conducting arms configuration. The main design standard is: high reliability and optimization of energy saving.

  • Induction Elements

    With more than30 years of experience manufacturing copper and aluminum busbar systems, our experts have been closed to specialist customers obtaining high knowledge about high current transmission. GECSA, company dedicated to the design, manufacture and installation of electric conductors of high intensities of copper and aluminum, also manufactures components for induction furnaces, both for manufacturers of equipment and for end users (foundries) or auxiliary companies that provide service. The specialization of GECSA in welding processes for copper, aluminum, stainless steels and their alloys using high intensity MIG and TIG procedures is noteworthy. Within the range of products supplied, the manufacture and repair of coils stands out, which is responsible for the production of the magnetic field in which the material is melted by electromagnetic effects.

    Coils For Crucible Furnaces

    GECSA manufactures and repairs induction coils, according to drawing. The coils are formed by a copper profile of different shapes and sizes depending on the design, circulating the flow of cooling water inside. Once the profile is formed, it is isolated by means of paints, varnishes and protections of various insulating materials. Previously, the cooling connection terminals will have been welded to the copper profile. Ultimately epoxy type materials are placed to insulate the coil from the boiler. The most frequentrepairs are the elimination of cracks and leaks. Also, measurement ofearth fault is made,checking isolation, as well as replacement ofthese. GECSA can supply refractory protections to install directly on furnace.
