Single-phase Converter Transformers

Transformers are designed for use with thyristor converters. In standard design, the transformers are adjusted to fastening by means of a base welded into core or screwed angles.
If agreed, the transformers may have more tappings. The windings terminals may be placed on one side only, or on both sides of a transformer.

Upon request, the transformers may be assembled in enclosures with the protection degree of IP 23, IP 44 and IP 54 with the possibility to insert supply cables through glands.
