What Determines the Cost of Power Transformers -
Miracle Electronics
Transformers are manufactured in a variety of
designs and in relatively short batches to meet
the demands of customers who always have
different expectations. There are a range of
solutions that can be applied to build different
collections of transformers. For example,
different magnetic materials can be used to
change the induction and density or the ratio of
copper to steel quantities can be altered from
12 to another relevant ratio. All these
variations result in fluctuations in the cost of
transformers.
Miracle Electronics is a leading power
transformer manufacturer in India that undertakes
requests for custom design and development of
its products, while providing transformers that
are RoHS Compliant, Reach Compliant, and
available with CE and UL marks with request. So,
you can tie up and get the most appropriate power
transformers that suit your application type and
fit your budget. There are many components that
define the cost of a transformer. Listed below
is a detailed record of the factors that affect
the cost of power transformers. Material and
Measurements of Wire Used Copper is the most
fundamental material used in a transformer that
plays a significant role in its price. The
weight of copper used in the transformer decides
the cost. For a 50 watt transformer, there is no
significant representation of the weight of
copper in the price, but

when there is reinforced insulation in the wire,
the length of the wire defines the cost.
Insulation in the wire keeps the cost low when
used for low turn count winds. With the current
going higher, the cost of the wire increases.
Similar to the length, the cost increases even
with the diameter of the wire. Larger reinforced
insulated wires are more expensive as compared to
the basic wires. Another major factor that adds
up to the wire cost is the amount of power the
wire handles. Flying Lead Connectors Flying
lead connectors are connectors with a set of
wires attached to one end while the other end
being loose or flying. Since these connectors
reduce the size of the extended rail bobbins,
they are also one important factor that plays a
role in the price. Because these flying lead
connectors are manually installed into the board,
they add to the production cost for additional
manual labour. Manufacturing Processes Utmost
care must be taken while manufacturing
transformers. Especially the process of winding
insulated wires must be done with special care so
as to avoid any kind of damage. Coils that are
made with human precision assure reliability and
better quality. The process involves soldering
which adds up to overhead costs of the
transformer. Margin Tape A margin tape is used
for every single wind in order to correspond with
clearance distances. This also adds up to the
overhead category just like soldering because it
is a part of the production procedure. Most of
the cost of power transformers is related to the
production procedure and the manual labour
involved in the construction. Since copper is a
scarce material, the size of the wire is closely
related to its price too. For more information
