DESCRIPTION
ABB Power Products - Medium & High Voltage Transformers Cast Resin Trasformers ABB Power Products ABB TDC voltage transformer for medium voltage systems has all parts of its primary winding, including terminals, insulated from the earth at a level corresponding to its rated insulation level . Indoor dry type, cast resin insulated medium voltage (MV) transformer for measuring and protection with up to 2 secondary windings. 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. ABB TDC Voltage Transformer ABB MV Medium Voltage Transformers - Voltage Transformer Features Indoor dry type, cast resin insulated transformers for medium voltages (MV). ABB transformers are suitable for measuring and protection of MV medium voltages with up to 2 secondary windings. ABB offers a full range of medium voltage (MV) and high voltage (HV) transformer products and solutions for ANSI, IEC and other local standards. ABB is a major transformer manufacturer throughout the world and offers both liquid-filled and dry-type transfomers for medium and high voltage power distribution, measurement and protection. T&D distribute ABB fuses, vacuum contactors, surge arresters, capacitors, plugs and sockets for LV, MV and HV electrical distribution and cable systems.TRANSCRIPT
DescriptionThe TDC 4 voltage, double-pole insulated transformers are cast in epox 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 voltage factor of 1.2 x Un. All the parts of the primary winding of the transformer are insulated from the earth, including the terminals, to an insulation level identical with the rated insulation level. When operating in a three-phase system the primary inlets of the transformer are connected across the respective lines, to the phase-to-phase voltage, mostly in the „V“ type of connection. The majority of the transformers is equipped with one secondary winding, intended to be used for either the measurement or protection purposes. One of the terminals of each secondary winding has to be earthed during the transformer operation.If not required otherwise, the secondary winding is lead out into a cast secondary terminal board.The transformer may be mounted in any position. The transformers are fixed by four screws, The M8 bolted earthing clamp is located on the transformer base plate. The secondary, sealable terminal board is covered with a transparent cover made of plastic material.

DescriptionThe TDC 7 double-pole insulated voltage transformers are casted in epox resin and designed mostly for insulation voltage 36 kV. Insulation voltages different from the above are to be the subject of an agreement between the manufacturer and the customer. If no a different value is required the transformers are manufactured with a overvoltage factor of 1.2 x Un. Both outlets of the primary winding, including the respective terminal is insulated from the earth to a level which corresponds to the rated insulation value. Most of the transformers are equipped with one secondary windings. One terminal of each secondary winding has to be earthed during the transformer operation. The transformer can be mounted in any position. The transformer are fixed by four screws. The secondary terminal board is covered with sealable cover.
Secondary wiringThe terminal box is entirely metal and provided with two detachable threaded inserts, Pg 16. Degree of protection is IP 30. The terminals are provided with M5 screws for the termination of the secondary wiring and with throughgoing holes for direct earthing of the secondary circuit by M6 screws. The terminal cover is sealable.
