Distribution Transformers

General Information

Description

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.

GEAFOL - Cast Resin Transformers

Description
Details

GEAFOL transformers have been in successful service since 1965. Many licenses have been granted to major manufacturers throughout the world since then. Over 80,000 units have proven themselves in power distribution or converter operation all around the globe.

Advantages and applications

GEAFOL transformers in ratings from 100 to approximately 40,000 kVA and lightning impulse (LI) values up to 250 kV are full substitutes for oil-immersed transformers with comparable electrical and mechanical data. They are designed for indoor installation close to their point of use at the center of the major load consumers. The exclusive use of flameretardant insulating materials frees these transformers from all restrictions that apply to oil-filled electrical equipment, such as the need for oil collecting pits, fire walls, fire extinguishing equipment. For outdoor use, specially designed sheet metal enclosures are available. GEAFOL transformers are installed wherever oil-filled units cannot be used or where use of oil-immersed transformers would require major constructive efforts such as inside buildings, in tunnels, on ships, cranes and offshore platforms etc.
