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.
Offered in 50 kVA and 75 kVA ratings, this single-phase oil-filled transformer steps a 13.2 kV primary down to 240 V or 480 V at 50/60 Hz (custom on request), housed in a sealed cylindrical tank built for outdoor utility-pole service. Copper or aluminium windings and IEC-aligned certification support reliable single-phase distribution for residential, rural and light-commercial networks.
High-voltage porcelain bushings are fitted to the cover of the sealed cylindrical steel tank, with low-voltage terminals on the side and integral brackets for pole mounting. Being oil-filled and hermetically sealed keeps the windings free of moisture while the oil provides cooling, so the unit delivers dependable single-phase output with minimal maintenance.
Overhead distribution lines for residential neighborhoods, rural electrification, farms, streets and light-commercial loads needing 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 included.
The rated capacity is 50 kVA & 75 kVA, with an input voltage of 13.2 kV (or custom). Other ratings in the same series are quoted on request.
