transformers
OSM single-phase, dry-type, multipurpose, general-duty 0.063
to 4.0 kilovolt-ampere transformers are designed for use in various sectors of
the national economy.
These transformers are to be connected to AC electric
mains with a frequency ranging from 50 to 60 Hz.
- Operation up to 1000 m above sea level.
- When
operated at altitudes higher than 1000 m above sea level, the capacity decreases
by 2.5% for every 500 m.
- Ambient working temperature: +40 to -60 degrees.
- Climatic embodiment type: U3.
- Protection rate: IP00.
- Heat-resistance
class of winding insulation - B.
- These transformers belong to the built-in
type.
