CORNER

• A DC or Direct Current busbar system carries electricalcurrent around a plant when AC or Alternating Currentcan not be used.

• These systems usually carry very large electrical currentsof between 15,000 Amps and 100,000 Amps

• Due to the large currents involved the systems use heavysections of copper to conduct the electricity

• With the heavy sections of copper involved a significantsupports structure is required.

• Systems can also be manufactured from Aluminium

What is a DC Busbar System?SYSTEMS

CORNER

• DC Busbar systems are used extensively inthe refining of chlorine

• This refining produces a number ofproducts such as:– Caustic Soda– Liquid Chlorine– Chlorine Dioxide

• These products are used in a number ofareas such as for the production of bleachwhich is used to treat wood pulp for newsprint

• For example MSS India has supplied aBusbar system to Tamil Nadu Pulp andPaper Ltd for their new bleaching plant ICI Chlorine Electrolyser Refinery
