The CG Power Systems Unit Substation delivers maximum versatility in a fully metal clad distribution system using a galvanised underbase with transformer, HV switchgear ring main unit and LV 4, 5 or 6 way fused distribution system. The whole package is delivered as a finished assembly and only requires cabling. The galvanised underbase allows a simplified foundation such as a precast concrete sleeper system. Double or triple front access doors enable separate access to the HV switchgear and the LV equipment. The modular concept enables the RMU or LV equipment to be removed without opening up the transformer or removing oil.
