Values above are drawn from the supplied product data. Final dimensions, materials, colors and packaging are confirmed once the sample is approved and the order finalized.
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.
Spanning five ratings — 25, 50, 75, 125 and 250 kVA — this single-phase oil-filled pole-mounted transformer steps a 13.8 kV primary down to a configurable low-voltage secondary for overhead distribution. The sealed cylindrical tank suits outdoor pole mounting, and copper or aluminium windings carry IEC-aligned certification appropriate for residential, rural and light-commercial service.
The sealed cylindrical steel tank carries high-voltage porcelain bushings on its cover, low-voltage terminals along the side, and mounting brackets ready for pole attachment. The fully sealed, oil-filled build keeps the windings free of moisture and lets the oil provide cooling, so the transformer holds up reliably with minimal servicing across the whole rating range.
Overhead distribution lines for residential subdivisions, rural electrification, farms, streets and light-commercial loads that call for single-phase pole-mounted step-down.
Capacity, HV/LV voltage, winding metal, bushing style and mounting hardware can be adapted to local grid standards, ANSI and IEC included.
The rated capacity is 25 / 50 / 75 / 125 / 250 kVA, with an input voltage of 13.8 kV (or custom). Other ratings in the same series are quoted on request.
A complete ratings ladder — 25 / 50 / 75 / 125 / 250 kVA — on a single platform; Fully sealed, oil-filled cylindrical tank built for long outdoor duty with little upkeep; Purpose-built for pole and overhead-line mounting with integral brackets.
