Totally Enclosed Non-Ventilated transformers
Totally enclosed non-ventilated transformers are highly suited for applications where the atmosphere contains conductive, corrosive, or combustible materials which might damage a transformer, or lint and dust which might block the ventilation passages. With no openings in the enclosure, heat is dissipated by radiating from the surface area of the enclosure.
Voltage class
600V
Ratings
Single-phase
15 - 167 kVA
Three-phase
15 - 1000 kVA
Winding conductor
Aluminum or copper
Core features
- Totally enclosed non-ventilated transformers are specifically excluded from the scope of U.S. DOE energy efficiency requirements
- Standard NEMA 3R enclosure; optional 3RX, 4, 4X, and 12 (X suffix enclosures ratings made of stainless steel)
- Includes copper or aluminum windings
- Available in 80°, 115° and 150° C rise designs
- Provides versatility for indoor/outdoor applications
- Transformers include a versatile bonding/grounding bar affixed to the bottom panel as standard, to provide compliance with NEC 450.10(A)
