HPS Fortress commercial potted transformers from Hammond provide an innovative design that is ideal for commercial applications where quality, ease of installation, and low cost are key. All Fortress units are encapsulated power transformers 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.
