SLIM® Transformer

STC’s SLIM® Transformers, using DuPont NOMEX® high temperature resistant insulation are especially made to answer the requirements of the transformers wherein installation space and safety is to be considered.

STC’s SLIM® transformer has a higher mechanical and dielectric strength due to the presence of high temperature resistant insulation SLIM® tramsformers are provided with high temperature fluid (silicon fluid or BIOTEMP)


Advantages of SLIM® Transformer:

The special insulation's high-temperature resistance improves the transformers reliability. Higher overload capacity gives longer life expectancy of the transformer. NOMEX® thermal protection in combination with BIOTEMP or SILICONE oil makes possible to achieve a compact dimension. Lower losses can also be achieved compared with conventional insulation.

The SLIM® transformer is suitable to be installed in areas where space and safety factor are to be considered as critical parameters.
