For low voltage, high current, DC systems and in some high voltage AC power supply applications, the requirement is for safe and reliable distribution of power from rectifiers, battery rooms and substations to the point of utilisation. GKW have designed, installed and commissioned Open Busbar systems for a wide range of uses, including the electrolytic reduction of zinc and magnesium, smelting of aluminium, refining of copper, electrothermal processing of metals and chemical processes involving electrolysis, as well as conventional switchyard work up to 400kV. In each case our project team has drawn upon our combined company experience and skill set to design and construct an installation that is totally effective and efficient.

Open Busbars are made from either rectangular section or tube, in both aluminium and copper, which are welded or bolted together longitudinally to form a continuous conductor. For the larger currents, up to 300000A they are made from extruded, rolled or cast aluminium, or from extruded or rolled copper. Connectors are made to suit the installation and, if necessary, an appropriate finish is applied to provide protection against atmospheric or process conditions encountered on site.

The highest standards of workmanship are applied throughout all stages of manufacturing. Our quality control procedures are supported by our own test laboratory with mechanical and non-destructive testing to achieve utmost reliability. On-site skills are particularly important in busbar installations where bolted joints must be carefully prepared to minimise joint resistance. Our on-site welding is to the same high standard as manufacture. Attention to site planning at the earliest stages ensures that installation can proceed to the client’s programme.
