Dry Type Transformers
Transformers meant to be installed ina dry and air conditioned room or in a PTI AUGIER type substation.
Benefits of dry type transformers
Impregnated transformer, environemental resin
- According to IEC 60076, NF C 17-200, standards
- Off load tap changers
- Protected by thermal probes
- Robust transformer long service life
Specifications of dry type transformers
- Power rating From 5 to 630 kVA
- Primary voltage Every voltage compatible with insulation voltages above
- Secondary load voltage 230 V - 400 V - 950 V - 3200 V - 5500 V and 6600 V
- Insulation voltage 1,1 kV - 3,6 kV - 7,2 kV
- Primary and secondary connesion on copper clots, by the uper side of the transformer.
- HRC fuses protection integrated above the protection envelop.
- Thermal protection by thermal probe integrated to windings, one or two thresholds protection.
- Standard : Three-phase transformer : Step-down Dyn11 - Step-up YNd1 - single-phase transformer: Iio
- Specific : Three-single tranformer, Leblanc three-two transfrmer, other couplings on request.
- Empty serring plugs : Three outputs on slots
- two earthing switches
- Lifting lugs
- For rollers for 10 kVA and higher power rating transformers
Features of dry type transformers
Transformers mechanical and electrical characteristics art the same for the step-down or step-up transformers.
Step-up transformers are built so that inrush currents are limited
- The transformers are not reversible
Optional Functions of dry type transformers
Painted sheet metal enclosure with natural airing upwards, IP21.
Connexion on pluggable terminas 3200V or 5500V
- HRC fuses protection integrated above the protection envelop
- Thermal protection by thermal probe integrated to windings, one or two thresholds protection
- Tape chargers +/- 2,5 % +/- 5%.
- Keyhole locking of the protection envelop and or pluggable terminals
Standards met, our commitment
Conforms to NF C 17-200 - NF C 52-100 - IEC 60076 standards.
Other specifications on request. Routine tests U.T.E made on each transformer, specific tests on request
