View data sheetWhy TPEPL
Four things we can show you.
01
Type-tested, not just designed
Designs type-tested up to 20 MVA, 33/11 kV at CPRI and ERDA: temperature rise, lightning impulse and short-circuit withstand. Reports are available on request.
02
Tank to radiator
Tanks, pressed-steel radiators and corrugated fin walls are made in-house by our Mechanica Elec unit, so we control quality and lead time.
03
Losses you can capitalise
Every offer states guaranteed no-load and load-loss figures, so you can compare suppliers on lifetime cost, not just price.
04
Built for export
Designs to IEC, ANSI, BS and IS, with BIS-marked distribution transformers to IS 1180 (Part 1): 2014.
