Trasfor typical products for industrial plant application are:

  • Cast resin, medium voltage transformers and reactors up to 25 MVA and 36 kV with or without enclosure and protection degree from IP00 to IP66.
  • Dry type transformers and reactors up to 20 MVA and 24 kV with or without enclosure and consequent protection degree from IP00 to IP66.
  • Water cooled and special design transformers and reactors, heavy current up to 50 kA, multi components assemblies, customized design under technical specification, air or water cooled LCL filters for converters.

Heavy industries

Trasfor manufactures transformers and reactors for many different industrial applications. Our products are typically required where large amounts of energy conversion is necessary as well as for distribution systems.

The transformers and reactor used for these application have a customized reinforced construction characteristic from an electrical and mechanical point of view. Often these components work in environments with high humidity and pollution.

Typical applications are:

  • Steel mills
  • Mines
  • Paper mills
  • Aluminium Smelters
  • Electric Arc furnaces
  • Silicon production

Chemical plants

In this field, Trasfor designs power transformers with very high current (50KA) and forced water cooling (water circulates inside the windings). Here again the environmental conditions are very severe and tough and the transformers and reactors need to have an excellent resistance to corrosion, moisture dust and corrosive agents.

Typical applications are:

  • Chloride plants
  • Galvanic treatment lines
  • Industrial electrolysis

Coal mine

Technological advancements have made coal mining today more productive than it has ever been. Improvements in mining methods (e.g. longwall mining), hazardous gas monitoring (such as safety-lamps or more modern electronic gas monitors), gas drainage, electrical equipment, and ventilation have reduced many of the risks of rock falls, explosions, and unhealthy air quality.

Rolling mill

In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled.

If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process and cold rolling processes the most tonnage out of all cold working processes.

Typical Trasfor products are used in rolling mills converters for the steel plate surface treatment.

Silicon from the rocks

Silicon is commercially prepared by the reaction of highpurity silica with wood, charcoal, and coal, in an electric arc furnace using carbon electrodes. At temperatures over 1,900 °C (3,450 °F), the carbon reduces the silica to silicon. Liquid silicon collects in the bottom of the furnace, and is then drained and cooled. The silicon produced via this process is called metallurgical grade silicon and is at least 98% pure. Pure silicon (>99.9%) can be extracted directly from solid silica or other silicon compounds by molten salt electrolysis. This method has the potential to directly produce solar grade silicon without any CO2 emission and at much lower energy consumption.

Compressor Station Drive

A compressor station is a facility, also called a pumping station, which helps the transportation process and the storage of gas from one location to another. Transformers, special turbines, motors and engines normally pressurize gas. The size of the station and the number of compressors varies on the diameter of the volume of gas to be moved.

The underground gas storage industry is 100 years old and largely contributes to the reliability of gas supplied to consumers; in fact, it secures natural gas supplies regardless of the season, temperature, or force-majeure.
