All transformers are built with 220oC insulation and 150
oC temperature rise. For 115
oC rise add 10% to price and F to catalog number. For 80
oC rise add 20% to price and B to catalog number. Check with factory to verify dimensional changes and weights. For copper windings add 20%.
Standard high voltage taps: 4-2.5%, 2AN and 2BN. For
4-2.5% FCBN, add BN to catalog number.

All transformers are built with 220oC insulation and 150
oC temp. rise. For 115
oC rise add 10% to price and F to catalog number. For 80
oC rise add 20% to price and B to catalog number, and check with factory for dimensional changes.
Standard high voltage taps: 4–2.5%, 2AN and 2BN. For 4–2.5% FCBN, add BN to catalog number.
Example: 1000 kVA, 3Ø, 60 Hz, 150oC temp. rise, 60 kV BIL, NEMA sound level, ventilated enclosure, 13.2 kV delta 480Y/277 = 100051H with 2-2.5% full capacity taps. 2AN and 2BN.
The correct catalog number for a 167 kVA, 2400/4160Y-120/240, 1Ø 60 Hz unit is 167S13H. The unit would be supplied with 2–2.5% above and 2–2.5% full capacity below normal taps on the primary.
