High voltage transformers manufactured by Dibao reach 15000V and are airproofed
with high voltage epoxy resin ,which enable their high isolation ability.
Three Phases Transformer manufactured by Dibao are mainly classified three phase
C-core transformer and three phase R-core transformer. Toroidal transformer are
also can be assembled as three phase transformer. These sort of transformers
enjoy the characteristics such as high efficiency, low temperature rise and low
Autotransformer has great advantages of small-size, low cost and high
efficiency. The adjusted ratio in voltages of audiotransformer is lower than the
usual transformer under the same situation, which becomes more obvious when the
distinction between primary and secondary' s voltage becomes less obvious. Generally,
the voltage ratio of autotransformer is rarely more than 2.Autotransformer's isolation
much be designed based on high voltage for the connection of primary and secondary' s windings .But autotransformer can not be used as isolation
transformer for the reason that they share the grounding point.
Audio transformer is working in a wide frequency band ,for instance, they works
at the range from 20HZ to 20KHZ .Yet power transformer is working in a fixed
frequency such as 50HZ,60HZ,400HZ,etc.The leakage flux and distributed
capacitance are key factors in the high-frequency point of audio transformer
while they are needless to be taken into account in power transformer. So for
audio transformer, it is necessary to reduce the leakage flux and distributed
capacitance in designing the coils' construction.
Waterproof Transformer has been treated with waterproof process and is
classified into different grades according to their waterproof ability. Water
proof transformer was mainly used in swimming pool ,pool, bath, outdoor lighting
,kitchen and the places where would touch the water. But the transformer must not
be permanently submerged in water.
Step Up Transformer, Step Down Transformer are usually used in the voltage match
for the appliances from different countries and can be classified into single
and three phase.
isolation Transformer owns excellent insulation between the primary winding and
secondary winding . Isolation Transformer is mainly used in the filtering of
industrial circuit , audio and instruments. And various isolation Transformers
meet different requirements of customers. Generally, isolation transformer has
the same input and output except for some special equipment which needs the
Lighting transformer is a type of power transformer used in lighting industry.
We mainly use toroidal transformer for lighting transformer such as halogen lamp
due to its low temperature rise and small size. The usual output of lighting
transformer is 12V and 24V or can be changed based on your requirement.
Power transformers manufactured by Dibao are mainly working in 50HZ,60HZ and
400HZ situation, which supply the different voltages for range of equipment.
Relevant type of transformer can be available according to the special
requirement. If you have any confusions while meeting the difficulties in
choosing the transformer, please contact us to seek advice.

O-core transformer as a special transformer wound from a continuous silicon
steel strip. It is wound into circular shape which is similar to toroidal
transformer. What is more ,O-core transformer resembles R-core transformer
having a circular cross section, which is different to rectangular cross section
of toroidal transformer. For there are no sharp corners, the coils can be wound
at much lower tension and will reduce the distributed capacitance between the
windings and increase the uniformity of magnetic field. So audio amplifiers and
other noise sensitive equipment all benefit from the excellent performances of
EI transformer is a kind of conventional transformer with simple construction
and much loss in working. Thanks to the productions of EI core and bobbins as
well as other attachments have come into a large-scale development, the prices
of them is low. Now the EI transformers have been widely used in different
fields and contribute to the most used transformer in electronic equipment.
C-core transformer is manufactured using oriented silicon steel strip and is
wound into rectangular shape after having anneal treatment ,bond and incision
compaction process. C-core transformer can be classified into ED type and CD
type. The C-core's bobbins can be wound with wires in advance before being fixed
into the cores, which differs from R-core transformer. And this production
process is suitable for making high voltage transformer.
R-core transformer is made to integrate the advantages of torodial transformer
and C-core transformer. Its construction has been said to be a revolution of
transformer in 90s.Core used in R-core transformer consists of continuous,
non-cut oriented silicon steel strip which has been completed the process of
anneal treatment and soakage in insulating paint. The special feature of R-core
transformer is there are two matched PBT fire retardant bobbins on each side of
the core. Each bobbin is separated in two parts, which makes the primary winding
and secondary winding enjoy complete isolation between the two windings. By
using special winding machines to turn the bobbins , realizing the copper wires'
winding process .
Toroidal transformer is manufactured on a high-speed automatic winding machines,
enjoys an ideal physical construction with the minimum of material. Thanks to
toroidal Core consists of idea grain oriented silicon steel strip and is wound
into circular shape, leakage flux can be restricted to a minimum level and a
higher percentage of the magnetic flux of toroidal transformer is being put to
much more effective use, achieving much higher electrical efficiencies than
conventional EI laminated transformer. Moreover, with the freedom in shape of
cores' designs ,toroidal transformer is available to different situations based
on sizes' requirements.
The toroidal transformers manufactured by Dibao are used special technical
processes in production, which settles the general short-circuit in windings.
With different measures in testing ,the high quality toroidal transformers are
guaranteed no matter what size of transformers would be.
