Description
|
|
|
Three-phase transformer in a housing IP 23, built as an isolation transformer conform to EN 61558-2-4. Basically this type size can be built in any vector group. If there is no vector group given, we use Dyn5 as default (star point can have full load from the outside conductor).
Please consider the difference between outside conductor voltage and phase voltage to star point at the different vector groups.
The housings are prepared for floor mounting. As cable bushing we use PG cable glands.
For a safe and easy transport, the transformers have crane hooks at the upper side.
Tauscher cast resin transformers need less space than comparable oil transformers. The transformers work without maintenance, they are flame-retardant and self-extinguishing. The insulation of the coils is made of environmental friendly polyurethane or epoxy cast resin.
