It is a traditional product of our company, including water-cooling and air cooling compensators, water-cooling and copper bar type copper buses, water-cooling and air cooling combination cable, copper tube forging in the furnace and rolled contact shoes free of collector rings. Besides, the system also includes the design, manufacturing, installation, adjustment of the complete set of hecvy-current conductor system and transformation of old furnaces. The short net of the submerged arc furnace is circuit with heavy current form the secondary side of the transformer to the electrode, which generally refers to the hard bus bar and is divided into two kinds as copper tube and copper bar. that the copper tube adopts the water cooling mode to save copper quantity is a trend for the future development. As the submerged arc furnace is developing to ward the large-scale, the arrangement of the short net is of vital importance to the conduction efficiency.
