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 

The sinusoidal tubular conducting busbar is an electrical conducting busbar, more specifically a conducting busbar having a sinusoidal tubular shape for use in electrical cabinets for switchgear and power control for low and high voltages and prefabricated electricity lines. The busbar has an initial fastening tab that is connected to a first sine curve, which is in turn connected to a joining tab, which is in turn connected to a second sine curve, such that said first sine curve and said second sine curve form a tubular region therebetween where there is no contact between said first sine curve and said second sine curve. Said second sine curve is linked to a final fastening tab or to a second joining tab, which is linked to a third sine curve, said third sine curve being linked to a final fastening tab.
