The totally sealed transformer is different from ordinary
oil-immerged transformer, it has cancelled the oil storage
cupboard, made the wing board of ripple fuel tank as the cooling
unit of dispelling heat , and which contracts and decreases with
the increasing of the volume of oil, make the inside of transformor
isolate with the atmosphere, prevented the degradation, insulated
and wet of the oil, which strengthened the dependability
performance . The users from Tianjin, Hebei, Shaanxi, Shandong
three provinces adopt the totally sealed series of products from.
our company. The products adopt the unison design across whole country,
performance accords with IEC. 76. 1~5, GB 10941~5 standard, and
passes ISO 9001 quality system authentication. The iron core adopts the high quality cold-reduced silicon sheet,
is made by the newest technology of seam of the ladder of German
GEORG company's iron core automatic production line, which improved
the magnetism and distribute within the iron core coherently
effectively, reduce the noise and loss. Coil adopts high strength
enameled wire coil, the drum type structure ( or the cake type ),
Fitted circle distributing evenly , rational insulate structure,
very high resisting ability of short-circle. The oil tank is the ripple structure, adopt blasting treatment on
the surface, afterwards use the special-purpose paint of
transformer, suitable for relatively abominable environment. |
