Transformer can transformer the voltage of a network into the voltage matching the system or load and fulfill power transferring and distributing.Taking the place of transformers with silicon steel core, AMDT can be widely applied in outdoor power distribution networks systems, which is magnificently energy saving and can lessen air pollution. It is especially applicable for areas with insufficient power supply and fluctuating load and where daily maintenance is hard. Since the transformer adopts a fully sealed structure, the insulating oil and the insulating medium are not polluted by the atmosphere, so it can be carried out in a humid environment, making the ideal power distribution equipment in the urban and rural distribution networks.

We manufacture transformer bushings for outdoor and indoor applications and our manufacturing program includes the following ranges :

1. Low voltage bushings in accordance with DIN 42539
- 1 kV , 250 A Low voltage bushing AB-250
- 1 kV ,630 A Low voltage bushing AB-630
- 1 kV ,1000 A Low voltage bushing AB-1000
- 1kV, 2000 A Low voltage bushing AB-2000
- 1 kV,3150 A Low voltage bushing AB-3150
2. Medium voltage Bushings in accordance with EN50180 & DIN42531
- 12.5kV,250A Indoor type transformer bushing 10Ni-250A
- 12.5 kV,250A Outdoor type transformer bushing 10Nf -250A
- 24 kV ,250A Outdoor type transformer bushing 20NF-250A
- 36 kV,250A Outdoor type transformer bushing 30NF-250A
