Stable power for non-ferrous metals


lstom Grid provides complete power distribution systems for plants producing non-ferrous metals such as aluminium, copper, zinc, cobalt.

Specific to these plants is the electrolysis process used for smelting, which requires huge volumes of DC power to be reliably supplied.

Our HV/MV/LV distribution systems for non-ferrous metals begin right at the mining head, leading on to the refining plant before the smelting and rolling mills.

Importantly however, for the electrolysis process, we provide complete DC connection substations, including the quality rectifiers and associated rectifier power transformer.

The systems also feature remote and local control cubicles and DC busbars with protection, as well as advanced high performance controllers with adaptive algorithms for the high current rectifiers.

In doing all of the above we are helping plants to guarantee their production of both ferrous and non-ferrous metals.

Our fields of expertise: 

  • Turnkey solutions
  • High voltage standard or customised substations
  • DC rectifiers/substations for electrolysis processes
  • Special power transformers
  • Secondary systems
  • Associated DC and AC power supplies
  • Service
