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.
Sold factory-direct at wholesale pricing, this low-loss single-phase oil-filled transformer is rated 100 kVA within a broader 10–500 kVA platform, stepping 13.8 kV down to 600 V (custom available). The sealed cylindrical tank is built for outdoor utility-pole mounting, and copper windings deliver high efficiency backed by IEC and related international certifications.
High-voltage porcelain bushings top the sealed cylindrical steel tank, low-voltage terminals sit on the side, and mounting brackets are built in for direct pole attachment. The low-loss core paired with copper winding lifts efficiency, and the oil-filled, hermetically sealed construction keeps the windings dry while the oil handles cooling — dependable, cost-effective single-phase service.
Overhead distribution circuits for residential neighborhoods, rural electrification, farms, streets and light-commercial loads needing efficient, budget-friendly single-phase pole-mounted step-down.
Capacity, HV/LV voltage, winding metal, bushing style and mounting hardware can be tailored to local grid standards, ANSI and IEC among them.
The rated capacity is 100 kVA (range 10–500 kVA), with an input voltage of 13.8 kV (or custom). Other ratings in the same series are quoted on request.
