The vector group consists of at least one capital letter and one small letter as well as of a reference number. Both wire and foil conductors can be wound depending on the current that is required.
With high rated currents streamlined copper wire and strip copper wire are used. All power specifications refer to the collected power at the secondary side with: This demands an enormous amount. Over the past Also available with CSA-label! The second reference number marks the protection against the penetration of water. Transformers with Autowinding Autotransformers have a winding which consists of two parts. To make this website work, we log user data and share it with processors.

Further regulations, as for example certain marine classifications, can be considered upon request. Advantages During the production process Ruhstrat Dry-Type transformers undergo a resin impregnation under vacuum with following furnace drying.
The transfer of the other part of the output power is effected by means of direct current conduction. A straight length of wire moves through a uniform magnetic field. The capital letter stands for the input winding, the small one for the output winding.

LOW VOLTAGE DRY-TYPE TRANSFORMERS ACCORDING TO DIN EN (VDE /) TECHNICAL INFORMATION – PDF
Voltages Ruhstrat Dry-Type transformers can be offered with voltages up to 10, V. Vector Groups of Three-Phase Transformers The combination of the different connection systems for highvoltage winding and low-voltage winding is called vector group of the three-phase transformer. During its production the transformer has to undergo an impregnation with resin under vacuum and then vee is dried in a furnace.
