A shielded busbar has a casing having a duct housing, a conductor pack including three or more conductors arranged side by side, wherein each conductor extends along a longitudinal axis and has a rectangular cross-section. Each conductor has two primary lateral surfaces, which are opposite to each other, and two secondary lateral surfaces, which are opposite to each other, wherein each pair of adjacent conductors of the conductor pack are arranged side by side along respective primary lateral surfaces. The shielded busbar also includes two or more shielding elements extending along the longitudinal axis and made of magnetically shielding material. Each one of the two or more shielding elements has a primary plate that entirely overlaps a primary lateral surface of one or two of the three or more conductors, and wherein not more than one shielding element of the two or more shielding elements has a C-shaped cross-section.

The method for producing a transparent conductive substrate includes forming metal meshes on a flexible non-conductive substrate with high transmittance. It's unnecessary to use palladium as a catalyst in this method. The metal meshes are in the form of nano/micro wires and the conductive substrate has high transmittance of 80%-90% at visible light wavelengths of 390-750 nm.
