Our Hammond HPS Fortress is an encapsulated transformer for commercial applications.
All units are encapsulated with electrical grade silica sand and resin compounds which completely enclose the core and coil to seal out moisture, airborne contaminants and eliminates corrosion and deterioration.
Single phase ratings from 50VA to 37.5kVA
Three phase ratings from 2kVA to 75kVA
60Hz frequency (50/60Hz on four single phase voltage groups)
Electrostatic shield standard on all three phase units and single phase units from 750VA and up
What is an encapsulated transformer? Basically it just means that one or more of the transformers components are completely sealed.
