MINIATURE POWER DISTRIBUTION SUBSTATIONS
Standard Coastal 315kVA and 500kVA Miniature Substation
Our miniature substation incorporates either SF6 or Vacuum Circuit Ring Main Units subject to client specification.They meet the requirements of SANS 1874. We offer a range of various brands and makes of RMU's and circuit breakers ranging from Siemens, Lucy, ABB, Eaton, Schneider and LS.
Miniature substations are equipped with high quality oil cooled transformers that comply with SANS 780 and are sourced from local suppliers and manufacturers. Windings can be either copper or aluminium based on customer requirements.
We supply both coastal and inland specifications, manufactured in powder coated mild steel, 3CR12 or 304 stainless steel. Miniature substations are only required to comply with SANS 1029:2010/NRS 004:2010. Our busbars in the miniature substations are based on a type tested design.
