Water-cooled transformer & chokes Type 3LT-AFWF Noratel introduces a whole new range of transformers with water-cooled enclosure solutions for distribution and converter transformers, both low- and medium voltage. The AFWF design is based on well proven technology, Noratel emphasis on a high degree of customization for flexible mechanical solutions and ease of installation “on site”. The AFWF design transport heat loss effectively away from the transformer and the surroundings so that a stable ambient temperature is obtained regardless of the location / season. AFWF design also reduces cooling power requirement from ambient temperature. Application: Typical applications will be shipbuilding, offshore and process industries where there are requirements for low cooling effect from ambient temperature. Technical details: Designed in accordance to IEC60726 and IEC60076 standards - CE-marked ■ Low noise level Standard power ratings from 400 kVA to 5000 kVA, other sizes on request AFWF design Freshwater cooler (maximum 38°C on supplied water) ■ Leakage guard, water meter and PT100 sensors in transformer and capsule air Water cooled chokes Noratel also introduces a program of direct watercooled chokes with a design based on water-cooled aluminum cooling elements in the windings. Cable entry from bottom or cutomized Effective fan driven radiator cooling up to 30% more power ■ Radiator coolers with single or double cooling tubes Operating voltage for internal use are taken from main transformer or integral control power transformer ■ Design based on 5 standard capsule sizes
