Designed and tested to IEC 60076 / 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.
This prefabricated European-style package substation handles three-phase medium-voltage input at 11 kV, 33 kV, 35 kV or 36 kV and steps it down to a 400 V / 415 V output. HV, transformer and LV rooms sit together inside one ventilated all-metal cabinet, so the unit can be dropped on site and connected quickly outdoors.
Fits industrial parks, mining and infrastructure sites, commercial developments, and utility medium-voltage distribution networks.
Enclosure colour, input voltage class, capacity, winding material (copper or aluminium) and compartment layout are all available to order.
Manufactured to confirmed specifications. Please share the capacity, voltage ratio and site conditions needed when you enquire.
Images shown are illustrative renders for marketing purposes; the finished unit is manufactured to the specifications confirmed at order.
Accepts four input voltage classes: 11 kV, 33 kV, 35 kV and 36 kV; HV, transformer and LV compartments integrated into one enclosure; Heavily louvred doors promote natural airflow and heat dissipation.
