  • Publication number: 20230109751
    Abstract: “SINUSOIDAL TUBULAR CONDUCTING BUSBAR” refers to an electric conductor busbar, more specifically a conductor busbar, with a sinusoidal tubular shape, applied to electric cabinets to control and switchgear assemblies for low and high voltage and prefabricated power lines. The busbar has an initial crimping tab connecting to a first sinusoid, which in turn connects to a junction tab, which in turn connects to a second sinusoid, so that said first sinusoid and second sinusoid form a tubular region between them, wherein there is no contact between said first sinusoid and second sinusoid. Said second sinusoid is connected to a final crimping or even a second junction tab, which is connected to a third sinusoid, with the said third sinusoid being connected to a final crimping tab.

  • Patent number: 11432646
    Abstract: Structural Column and Modular Structure for Electrical Cabinets Comprising said Structural column, includes a structural column (1) which, from a single piece, accurately determines two corners or vertexes of a modular structure (19) for electric cabinets. The modular structure (19) has four vertically positioned structural columns (1) and at least eight horizontal beams (20) connected to each other by means of screws (21). This invention also introduces an innovative joint between the elements of the structural columns (1), which are joined together by means of welds (6) and with the aid of limiters (12), positioning flaps (11) and engagers (9). Thus, this invention guarantees a perfect square of the modular structure and the correct assembly of the electrical cabinet, with no need for highly specialized labor. The modular structure (19) presented here can be manufactured entirely from low-cost metal materials such as carbon steel, significantly reducing the manufacturing costs of electrical cabinets.
