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.
