Transformers are ordered in
single or three phases.
Ideal Transformer uses mineral
oil with or without additives in its production. If requested, incombustible oil is also used.
cooling (ONAN) and Forced cooling (ONAN/ONAF) are used in production.
It is produced hermetically
with an expansion tank open to the atmosphere, closed to the atmosphere, or
with a gas cushion.
It is produced with a no-load
tap changer or an on-load tap changer.
It is produced with a cable
box or protection box.
It is produced with a porcelain
insulator or plug-in bushing.
Copper or aluminum is used as conductors
in low-voltage windings.
Windings are produced from
sheet or rectangular paper or Nomex insulated wire.
If the windings are made of
sheet, shellac paper (DDP) with increased base strength and coated with resin
is used as layer insulation.
In high-voltage windings,
copper or aluminum conductors are used depending on the customer's request.
Due to the strip insulation
paper (kraft or thermally improved shellac) layer insulation is formed in the
form of a wedge.
The special structure of the
layer insulation increases the resistance against the impact voltage; It helps
to form gapless, solid, and excellent-quality coils.
