Distribution Transformers for the Philippines
Overhead and pad-mounted distribution transformers built for the Philippine grid at 60 Hz: 13.2, 13.8 and 34.5 kV primary, with 230 V, 254/440 V and 480 V secondaries. Single-phase pole-mounted units and three-phase substation units are both within our range.

Everything for the Philippines is built and factory-tested at 60 Hz.
Coastal and typhoon exposure drives the enclosure, corrosion protection and fitting spec — tell us the site and we build to it.

Oil immersed or cast resin?
- Oil immersed: outdoor substations, pole and pad-mounted duty.
- Cast resin: indoor rooms and sites where fire rules restrict oil.
- Tell us where the unit sits and we will specify the build.
Where these units are used
Questions buyers ask
Yes. Philippine units are wound and factory-tested at 60 Hz, and the test report states the test frequency.
Yes — single-phase pole-mounted units from 15 to 333 kVA sit inside our distribution range, alongside three-phase pad-mounted and substation units.
We build to IEC 60076 and ANSI C57 as applicable to the order. Tell us what the utility or the cooperative specifies and we match it.
