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 for 1500 kVA at 33 kV, this prefabricated European-style box substation packs a complete medium-voltage distribution point into one weatherproof steel cabinet. High-voltage, transformer and low-voltage compartments are combined in a single all-metal housing, giving industrial parks, commercial sites and utility networks a substation that arrives ready to connect and energize.
Suited to industrial parks, commercial and residential developments, municipal distribution networks, and medium-voltage utility grids.
Enclosure colour, capacity and voltage class, winding material (copper or aluminium), and compartment layout can all be adjusted to order.
Every unit is manufactured to the buyer's confirmed specification. When enquiring, please share the required capacity, voltage ratio and site conditions.
Images shown are illustrative renders for marketing purposes; the finished unit is manufactured to the specifications confirmed at order.
The rated capacity is 1500 kVA, with an input voltage of 33 kV. Other ratings in the same series are quoted on request.
Three functional compartments — HV, transformer, LV — combined into one compact footprint; 1500 kVA output at 33 kV, matched to medium-voltage distribution needs; Arched-roof steel housing built for continuous outdoor exposure.
