4. Structure feature 

(1). The product is cast in epoxy resin.

(2). The transformers are equipped with primary winding and secondary winding.

The windings are fixed to their on core bar by casting.

(3). For the two secondary windings, the first one is for either measuring or

protection purposes;

the other is for being connected into an open-delta connection in a three-phase system.

(4). The outlet of the primary winding is insulated from the earth to a correspondent level.

(5). The secondary terminal board is covered with a transparent cover made of plastic.

(6). The bolted earthed clamp is located on the transformer base plate.

(7). The transformer is fixed onto the base plate by four screws.
