Amorphous alloy
oil-immersed transformer
Product introduce
Transformers can transform the voltage of a network into
the voltage matching the system or load and fulfill power transferring and
distributing. Replace the transformer with a silicon steel
core. AMDT can be widely applied
in outdoor power distribution network systems, which is magnificently energy
saving and can reduce air pollution. It is especially applicable for areas with
insufficient power supply or fluctuating load and where daily maintain is hard.
The hermetically sealed construction of AMDT prevents the oil and insulation
material from being polluted, so the unit can serve in a humid environment.
AMDT are the ideal equipment supplying power for distribution network in urban
and rural areas.
Advantage of structure
The core is wound with
amorphous alloy ribbons, which possesses a no-load loss 80% lower than S9 type
transformer(with silicon steel core); The LV coils are wound with copper foil,
which reinforces the ability to withstand short circuit for the transformer
AMDT with connection Dyn11 can lighten harmonics impact on the network and
improve the quality of the power supplied; The tank and cover are welded
together, forming a hermetically sealed construction which lengthens the
service life of AMDT and makes it repair-free; The vacuum oil filling
eliminates all bubbles in the coils to ensure stable characteristics of
insulation; Each transformer passes a full-wave lighting impulse test before delivery
to ensure its safety operation. A peak voltage 25% higher than the value
required by national standard is applied during the test.
