Dry Type Transformers

Product catalog summary

Overview: Trafotek specializes in manufacturing dry type transformers tailored for demanding applications, particularly in marine operations and frequency converters. Their product range includes transformers from 1 kVA to 12.5 MVA and voltages up to 17.5 kV.

Specifications: Trafotek transformers are designed with various winding materials (copper or aluminum), insulation systems (vacuum impregnated or cast resin), and cooling methods (AN, AN/AF, AF, AFWF) to optimize performance. They offer transformers with 12 and 24-pulse configurations to reduce Total Harmonic Distortion (THD) in low and medium voltage applications.

Cooling and Enclosure Options: Cooling methods include natural air (AN), forced air (AF), and air/fresh water (AFWF). Enclosures are made from dismountable sheet steel with options for different protection degrees (IP23, IP44, IP54) and installation environments (indoor, outdoor).

Transformer Types: Trafotek offers HT, CT, LT, drives, distribution, control, isolation, and excitation transformers. Each type has specific power ranges, core technologies, voltage classes, and insulation technologies.

Key Features: Options include voltage tappings, earthed copper screens, temperature sensors, anti-vibration dampers, and integrated pre-magnetizing transformers. AFWF transformers are highlighted for their efficiency in space-restricted environments like marine and oil industries.

Certifications: Trafotek transformers are certified by various third-party organizations for marine and offshore applications, including LR, RINA, GL, DNV, BV, ABS, RMRS, CCS, PRS, KR, and NK.

Contact Information: Trafotek is located in Turku, Finland, with contact details provided for further inquiries.
