Advantages – Amorphous Metal
Distribution Transformer
Common Metallic Solid are crystalline, regular and periodic having structural anomalies in Atomic arrangement which hinder Magnetization Process due to no crystal grain boundary. Amorphous Structure Randomized by process having absence of regular structure which helps Magnetization Process.

Cost Benet in
terms of TOC
Proven technology for
installation in grid; No
special technique required
Proven technology for
production; UAML will teach
technology and support start-up
of production at transformer makers
Easy magnetization occurs by
means of low coercivity, low
hysteresis loss, high
permeability
Low magnetic losses occur by
means of low coercivity, low
eddy current loss, high
permeability, high resistivity
Fast flux reversal occurs by
means of low magnetic loss
Best performance under
harmonics (Non-Linear Loads)
Less temperature rises of core
and short circuits
Reduction in fossil fuel
consumption
and Greenhouse Gas
Reduced cost of generation per
kWh consumed
Easy to repair or
replace coils
Lesser CO2 Emission
The losses due to induction in the cores produced with various transformers sheets.

- Main Difference in DT
between AMDT and
CRGO-DT is just a core -
You can produce AMDT
using traditional technique. -
Many people are worried that
AM-core is very difficult to
handle. But handling of
AMC becomes easy after
they have some experience - Several AMDT makers
have mastered its
production - UAMLwill support
