Dry transformers TSL

Dry three-phase power transformers to lower voltage with resin insulation and capacities from 100 to 2500 kVA are intended for installation in industrial and public buildings, which have increased requirements for fire protection and environmental protection.

Dry three-phase distribution transformers TSL with resin insulation of the primary windings on the high voltage side are designed for 6 or 10 kV and a low voltage of the secondary winding for 0.4 kV. Scheme and connection group of the winding is Yyn-0 or Dyn-11

Design features

Dry transformers TSL are fire-resistant and can withstand very well work in the short-circuit conditions and are also easy to maintain and they are environmentally friendly. Thermal insulation class – F (155˚C).

Dry transformers TSL are produced without protective cover – protection class IP 00 (without protective cover).

Low voltage windings are made of aluminum or copper foil. High voltage windings are made of aluminum or copper wire.

Technology of filling molds with epoxy resin in vacuum conditions provides the same high quality and high resistance in winding for short-circuit current.

Dry transformers do not require time-consuming maintenance: There is no need for sealing of the transformer tank and its protection against corrosion, as well as cleaning of the oil.

Dry transformers with epoxy resin cast windings require only air for cooling. There is no need to control the oil level and its purification.
