Product details

This single-phase oil-filled pole-mounted transformer comes in 25 kVA and 50 kVA ratings, stepping 13.2 kV down to 120–240 V (custom available). Its compact, sealed cylindrical tank is designed for outdoor overhead mounting on utility poles, giving reliable power to residential, rural and light-commercial networks. Windings are available in aluminium or copper, and the unit is certified to IEC and other international standards.

Design & Construction

Two high-voltage porcelain bushings sit on the sealed steel tank's cover, low-voltage terminals are fitted to the side, and mounting brackets let the unit attach directly to a distribution pole. The oil-filled, hermetically sealed build keeps the windings dry and lets the oil manage cooling, so the transformer runs reliably with minimal upkeep.

Applications

Overhead distribution circuits for residential neighborhoods, rural electrification, farms, streets and light-commercial loads that call for single-phase pole-mounted step-down.

Customisation Options

Capacity, HV/LV voltage, winding metal, bushing style and mounting hardware can be adapted to local grid standards such as ANSI or IEC.
