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.
Built around IEC-compliant switchgear, this prefabricated containerized substation handles compact power distribution and transmission at 33 kV / 35 kV. The aluminium-zinc-coated, IP65-rated container brings switchgear, transformer, and low-voltage equipment together in one transportable, weatherproof unit with its own climate control.
Electric power transmission and distribution, industrial parks, mining and infrastructure projects, and any medium-voltage utility substation needing a complete, transportable solution.
Enclosure colour, voltage class, switchgear configuration, capacity, and climate-control features can be tailored on request.
Every unit is manufactured to order against confirmed specifications. Please provide the voltage class, switchgear scheme, capacity, and site requirements when enquiring.
The images shown are illustrative marketing renders; the unit actually delivered is manufactured to the specification confirmed at order.
