Product details

One platform, nine ratings: this single-phase oil-filled pole-mounted transformer is built from 15 kVA all the way to 333 kVA (15 / 20 / 25 / 37.5 / 50 / 100 / 167 / 250 / 333 kVA), stepping a 13.8 kV primary down to a selectable low-voltage secondary for overhead distribution work. The sealed cylindrical tank is designed for outdoor utility-pole service, and copper or aluminium windings carry IEC and related international certifications suited to residential, rural and light-commercial networks.

Design & Construction

Two porcelain high-voltage bushings top the sealed steel tank, low-voltage terminals sit to the side, and integral brackets let the unit bolt straight to a pole. Sealing the tank and filling it with oil keeps moisture off the windings while the oil manages heat dissipation — a combination that holds up across every rating in the 15–333 kVA line with minimal servicing.

Applications

Overhead distribution circuits for residential areas, rural electrification, farms, streets and light-commercial sites needing a single-phase pole-mounted step-down at any point in the 15–333 kVA range.

Customisation Options

Rating, HV/LV voltage, winding metal, bushing type and pole hardware can be tailored to regional grid codes, ANSI and IEC among them.
