Most GigaWatt devices feature a novel internal current distribution system directly to the output sockets. It is based on massive distribution bars, made from thick, polished slabs of copper, with a cross-section of 30mm2 each. Using separate bars allows for an even and stable power distribution, regardless of the draw on each output. All types of the bars are a proprietary GigaWatt design and were developed and manufactured by GigaWatt.
The manufacture of such bars is very expensive due to the quality and purity of the copper they are made from, as well as the technology applied. The distribution bars are made from the cleanest (99.99%) cathode copper Cu-OF (oxygen free copper with high conductance) and Cu-ETP (metallurgical refined copper with high conductance). The copper is enameled and annealed, what makes it denser and increases conductance, plasticity and resistance to corrosion in most environments. It is characterized with high conductance, low contamination and low residual oxygen content. Mechanical processing uses a technology that does not produce any heat, which could oxidize the copper and negatively influence the conduction parameters.
In the flag conditioner GigaWatt PC-4, and in products of the limited “Special Edition” series, the distribution bars are silver plated.
