Description The TJC 4 single-pole insulated voltage transformers are cast in epoxi resin and designed mostly for insulation voltages of 3.6 kV to 12 kV. If no other value is required the transformers are manufactured with a overvoltage factor of 1.9 x Un/8 hrs. One outlet of the primary winding, including the respective terminal is insulated from the earth to a level which corresponds to the rated insulation value. The transformer is mostly equipped with two secondary windings, the first one for either measuring or protection purposes, the other for being connected into an open-delta connection in a three- phase system. One terminal of each secondary winding and one of the open-delta connected terminals have to be earthed during the transformer operation. When not required otherwise, the secondary windings are lead out into a cast- type secondary terminal board. The transformer can be mounted in any position. The transformer ore fixed by four screws, the M8 bolted earthing clamp is located on the transformer base plate. The secondary terminal board is covered with a transparent and sealable cover made of plastic material. Rated primary voltages ... 3/√3 kV; 3,3/√3 kV; 6/√3 kV; 6,6/√3 kV; 10/√3 kV; 11/√3 kV Other primary voltages can also be supplied on request. Rated secondary voltages... 100/√3 V; 110/√3 V – accuracy classes 0.2; 0.5; 1 (measuring winding) or 3P; 6P (protection winding). Other secondary voltages can also be supplied on request.

ABB TJC MV Indoor Voltage Transformer : Indoor Cast Resin Voltage Transformer Single Pole Transformer
ABB Power Products - Medium & High Voltage Transformers
Cast Resin Transformers
ABB Power Products
ABB TJC is a single phase voltage transformer which is intended to have one end of its primary winding directly earthed. Indoor dry type, cast resin insulated medium voltage transformer for measuring and protection with up to 2 secondary windings. With or without fuses. Most electrical standards available. Reconnectable MV medium voltage versions available.
Cast Resin Transformers are constructed with their HV high voltage windings encapsulated in resin and are an excellent alternative to traditional oil immersed transformers. Cast resin transformers encase the windings in epoxy resin : these HV high voltage cast resin transformers simplify installation since they are dry, without cooling oil, and so require no fire-proof vault for indoor installations. The epoxy resin protects the high voltage transformer windings from dust and corrosive atmospheres.
