Three Phase Dual Voltage Oil-immersed Distribution Transformer
Product Description
A dual voltage transformer is a special type of transformer characterized by having two windings of different voltage levels to achieve two different conversions of input voltage.
Definition:
A dual voltage transformer refers to a winding with two voltage levels installed in the transformer.
It can convert the input voltage into another output voltage and has two output voltages simultaneously to meet different voltage requirements.
Structure:
A dual voltage transformer consists of at least one primary winding and a secondary winding, which are specially designed to achieve outputs of two different voltage levels.
A primary winding may include multiple taps for adjusting and switching voltage levels.
Principle:
By adjusting the series parallel switch to parallel or series connect various series parallel segments, voltage conversion can be achieved.
By adjusting the tap changer to cut off or connect some tap sections, the purpose of increasing or decreasing the number of turns is achieved, and voltage adjustment is achieved.
Application scenario:
Dual voltage transformers are widely used in various devices that require the use of different voltages, such as factories, offices, residential buildings, etc.
Especially for devices that require providing two different voltages simultaneously, such as some special electronic or industrial devices.
Advantages:
Meet the voltage requirements of different devices and facilitate adjustment.
Economically energy-saving, with small space occupation.
In summary, a dual voltage transformer is a very practical power equipment that can convert the input voltage into two different output voltages through two windings of different voltage levels to meet the voltage requirements of different devices.

Product Parameters
Transformer Chracteristics
Transformer Core
1. The core is made of high quality grain-oriented cold-rollled silicon steel of high magnetic conductivity, by using 45°five-stepping all leaning lamination way to laminat. So the no-load losss and the no-load current are reduced effiently.
Transformer Windings
LV windings
1. LV winding is manufactured with high quality foil conductor or copper wire, and the ampere-turn is balanceable.The additional loss is low and the ability of anti-short is improved.
2. Oil drains of heat dispersion aer scientifically used in the winding, and the surface of heat dissipation is increased, so the tempertature is reduced and the ability of over-load is improved.
HV windings
HV winding is manufactured with high quality copper wire and excellent design structure. It improves the distribution of electric filed. With lighting impulse analysis, the ability of anti-lighting impulse hase been improved.
