Matching transformers (Series: TMA and TTA)

Description Construction:

The windings of these transformers are made ​​of copper wire (double insulated with Class H insulation or double Nomex tape) or performed with aluminum tape. On request, a copper band version is possible.

The transformers are protected by a vacuum pressure impregnation with a solvent-free polyester resin and anschließßender heat treatment. The magnetic core is made ​​of EI and UI sheets (types 1, 5, 8 kVA) and grain oriented sheets (types 10 and 250kVA).

Applications:

These transformers are used to adjust the load voltage to the mains with a galvanic isolation between the two networks. It can also be a neutral conductor (insulated or grounded) are brought out.

Autotransformers can also adjust the tension, but there is no galvanic isolation between the networks possible.
