Designed and tested to IEC / GB. Millenium production is certified to ISO 9001, ISO 14001 and ISO 45001; the product family carries CE (ECM), UDEM attestation and an EAC declaration of conformity. Every unit passes routine factory tests before dispatch.
Rated at 1600 kVA with a 12 kV to 0.4 kV ratio, this three-phase European-style compact substation can be ordered with either a dry-type or an oil-type transformer. Its integrated steel housing combines the high-voltage, transformer, and low-voltage rooms in one well-ventilated cabinet, built for quick outdoor commissioning.
Well suited to industrial parks, residential and commercial developments, municipal power distribution, and medium-voltage utility grids.
We can adjust transformer type (dry or oil), enclosure colour, capacity, voltage ratio, winding material, and compartment layout on request.
Units are manufactured to order against confirmed specifications. Please provide the capacity, voltage ratio, transformer type, and site conditions when enquiring.
The images shown are illustrative marketing renders; the actual delivered unit is manufactured to the specification confirmed at order.
The rated capacity is 1600 kVA. Other ratings in the same series are quoted on request.
Delivers 1600 kVA capacity through a 12 kV-to-0.4 kV transformation; Buyer's choice of dry-type or oil-type transformer; Three separate compartments (HV, transformer, LV) built into one enclosure.
We can adjust transformer type (dry or oil), enclosure colour, capacity, voltage ratio, winding material, and compartment layout on request.
