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.
Available in 75 kVA and 100 kVA ratings, this single-phase oil-filled transformer steps 10.5 kV down to 400 V (custom ratios on request) for overhead distribution service. It shares the same sealed, cylindrical tank format built for outdoor pole mounting, and its aluminium or copper windings are certified to IEC and other international benchmarks, making it a dependable choice for residential, rural and light-commercial feeders.
The cover of the sealed cylindrical steel tank carries the high-voltage porcelain bushings, low-voltage terminals sit on the side wall, and mounting brackets are built in for direct pole attachment. Because the tank is oil-filled and hermetically closed, the windings stay dry and the oil provides efficient cooling — the reason this unit needs so little maintenance in single-phase outdoor duty.
Overhead lines running to residential developments, rural electrification zones, farms, streets and light-commercial connections that call for single-phase pole-mounted step-down.
Capacity, HV/LV voltage, winding metal, bushing style and mounting hardware can be matched to local grid requirements, ANSI and IEC included.
The rated capacity is 75 kVA & 100 kVA, with an input voltage of 10.5 kV (or custom). Other ratings in the same series are quoted on request.
Two ratings — 75 kVA and 100 kVA — in a common single-phase pole-mount body; Fully sealed oil-filled tank keeps outdoor maintenance to a minimum; Integral brackets built for straightforward pole and overhead-line fitting.
