Segmental assembly of windings as well the first and the second assembly of transformers of voltage class up to 750 kV is carried out in special “clean” rooms where dust fall is controlled.
All assembly works are performed with the use of lightweight, mechanical racks facilitating the mobility of production.
All transport movements are made by hover platforms.
Assembly of electrical scheme of transformer active parts is carried with the aid of a set of equipment used for preliminary forming and crimping of wires ensuring 100% control of all non-separable connections.
Drying of active parts of transformers is carried out in vacuum drying chambers produced by HEDRICH (Germany), applying the technology of vapour-phase drying with cyclic vacuum evaporation, under isostatic pressure on windings during drying.
