General Purpose
Transformers
|
Dry-type
transformers (encapsulated, ventilated or non-ventilated),
600 Volt Class, isolation type, single and three phase, through
500 KVA. Indoor and outdoor models available.
Any situation where the available voltage must be changed
to accomodate the voltage required by the specific electrical
circuit or connected equipment. FOr many electrical circuits,
the National Electric Code (NEC) requires a separately derived
neutral secondary connection provided by Delta-Wye connected
transformers. Typical applications include:
Hospitals
Office Buildings
Industrial Plants
Schools
Commercial Buildings
Shopping Centers
Apartment Buildings
High Rise Buildings
Institutional Buildings |
 |
General purpose transformers can be located close to the load. No vaults are required for
installation and no long, expensive feeder lines are needed. Common applications include
inductive and resistive loads such as motors, lighting and heating.
Sola/Hevi-Duty
general purpose transformers are manufactured to meet applicable industry standards, are
listed in accordance with UL506 and UL1561 specifications and are classified as isolation
transformers. |
