Specifications listed reflect the supplied product data. Exact dimensions, materials, colors and packaging are confirmed with the approved sample and finalized order.
Designed and tested to IEC60076 / 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 at 333 kVA and built to IEC 60076, this single-phase oil-filled pole-mounted transformer steps a 7.62 or 13.2 kV primary down to 120/240 V (custom on request). Its sealed cylindrical tank is shaped for outdoor utility-pole duty, and copper or aluminium windings, together with IEC and related certifications, make it a strong fit for higher-capacity residential, rural and light-commercial distribution.
The sealed cylindrical steel tank carries its high-voltage porcelain bushings on the cover and low-voltage terminals on the side, with brackets built in for direct pole mounting. Being oil-filled and hermetically sealed keeps the windings free of moisture while the oil manages cooling, delivering dependable single-phase performance to IEC 60076 with little maintenance required.
Overhead distribution feeders for residential neighborhoods, rural electrification, farms, streets and light-commercial sites where a higher-capacity single-phase pole-mounted step-down is called for.
Capacity, HV/LV voltage, winding metal, bushing style and mounting hardware can be adapted to regional grid standards including ANSI and IEC.
The rated capacity is 333 kVA, with an input voltage of 7.62 / 13.2 kV (or custom). Other ratings in the same series are quoted on request.
High-capacity 333 kVA single-phase unit built to the IEC 60076 standard; Fully sealed, oil-filled cylindrical tank for long outdoor service with minimal upkeep; Designed for pole and overhead-line mounting, brackets included.
