On the last transformation step from the power station to the consumer, distribution transformers (DT) provide the necessary power for systems and buildings.
Accordingly, ther operations must be reliable, efficient and, at the same time, silent. Distribution transformers are used to convert electrical energy of higher voltage, usally up to 36 KV, to a lower voltage, usally 250 or 435 V, with an identical frequency before and after the transformation. Application of the product is mainly within suburban areas, public supply authorities and industrial customers. Distribution transformers are usally the last item in the chain of electrical energy supply to households and industrial enterprises.
Distribution transformers are fail-safe, economical and have a long life expectancy. These fluid-immersed transformers can be 1-phase or 3-phase. During operation, the windings can be exposed to high electrical stress by external overloads and high mechanical stress by short-circuits. They are made of copper or aluminum. Low-voltage windings are made of strip or flat wire, and the high-voltage windings are manufactured from round wire or flat wire.

Three product classes are available: standard, special and renewable
Standard distribution transformers: Pole mounted, Voltage regulator
Special distribution transformers: self-protected DT, regulating DT (OLTC), or others
Renewable distribution transformers: Used in wind power stations, solar power plants or others.
