Specifications reflect the supplied product data. Final dimensions, materials, colors and packaging are confirmed with the approved sample and order.
Designed and tested to UL / 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.
Carrying UL certification, this single-phase oil-filled pole-mounted transformer is offered at 25, 75 and 167 kVA, stepping 13.2 kV down to 120/240 V (custom available). Its sealed cylindrical tank suits outdoor utility-pole installation, and copper or aluminium windings meet both North-American and international distribution requirements under UL, IEC and additional certifications.
The sealed cylindrical steel tank carries high-voltage porcelain bushings on its cover and low-voltage terminals on the side, with brackets built in for direct pole mounting. UL listing confirms suitability for North-American networks, and because the tank is oil-filled and hermetically sealed, the windings stay free of moisture while the oil manages cooling — dependable single-phase performance with little maintenance.
Overhead distribution circuits for residential neighborhoods, rural electrification, farms, streets and light-commercial loads where a UL-listed single-phase pole-mounted step-down is required.
Capacity, HV/LV voltage, winding metal, bushing style and mounting hardware can be adapted to local grid standards including ANSI and IEC.
The rated capacity is 25 / 75 / 167 kVA, with an input voltage of 13.2 kV (or custom). Other ratings in the same series are quoted on request.
