Transformer information and marking

Generally

The self-cooled single or three phase dry transformers with copper winding are produced according to the following standard ČSN EN 61558. Transformers are made according to catalogue sheets or customer specification. They are intended for permanent load.

Type

The transformer cores are manufactured from transformer lamination type EI, UI, FI, 3EI. The bobbins are composed of textitte, glass-textitte or are moulded plastic that can have two chambers. Class of heating insulation is B or F, on some cases H. The outlets of input and output voltage are led to the soldering tags, pins or terminal blocks or optionally are free. The transformers can be protected by a fuse. The voltage transfer is performed according to the customers wishes in a any combination from 1V up to 1000V. The transfer can be made with tapped winding or in case of specialpurpose - with more and mixed windings. It is possible to equip the transformers of one chambered coils with shielded winding. In case of enquiry for more windings it is necessary to give the voltage and capacity in VA (or current in A) with each output voltage. The type is standard, safety isolating, isolating or special.

Testing

The transformers are tested according to respective standards and customer requirements.

Acceptance and supply

If not agreed in another way the acceptances takes place at the plant of the supplier.
