Customized Oil-Immersed Power Distribution Transformer
The Oil Immersed Transformer series are the kind of the transformer with low noise, low loss and low partial discharge. With rational structure, high-quality material,scientific design, strict craftsmanship and advanced test method, the characteristics of this series products are as follows:
Excellent dynamic thermal stability, outstanding short-circuit resistance, high lighting impulse resistance, high reliability.
Low lose, energy conservation, run economically and maintenance free.
Contour artistic, compact size, low installation and maintenance costs.
C226Performance and parameter conform to or excel the standards of IEC.
Fully Hermetically oil tank, effectively preventing air from eroding oil and prolonging the service life of the transformer
OUTLINE DRAWING
CONSTRUCTION:
CORE
The core is manufactured from cold-rolled grain oriented, (CRGO) silicon steel. The steel sheets are cut into required dimensions on automated
machines thereby ensuring reduced air gap, low exciting current and low noise. Each lamination is insulated from each other to ensure a long trouble-free lifetime of the core. Using 45° stepping all leaning lamination way to laminate. So the no-load current are reduced efficiently.
WINDINGS
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. Oil drawings of heat dispersion are scientifically used in the winding, and the surface of heat dissipation is increased, so the temperature is reduced and the ability of over-load is improved.
temperature is reduced and the ability of over-load is improved.
HV winding is manufactured with high quality copper wire and excellent design structure. It improves the distribution of electric field. With lighting
impulse analysis, the ability of anti-lighting impulse has been improved.
TANK
The tank is jointed with high-quality steel. The surface is eliminated rust phosphate coating and pained with the type of FVC anticorrosive paint. It has
ability to prevent the corrosion from oil and chemical matter. It can be broadly applied to outdoors with bad environment for its contour artistic, easily
installation and maintenance free.
INSULATION OI L
The insulating oil is inhibited, without PCB and generally complies with IEC60296.

4. Strong overload capability for long-term operation at 150% loading.
TEST REPROT:
1. ISO 9001 Quality management system certification
2. ISO 14001 Environmental management system certification
3. PCCC Certificate of qualification
4.National electrical safety quality testing center certificate of qualification
5.Occupational health and safety management system certification
Process Technology:
Core:
Our transformer's core is made of high quality cold rolled grain oriented silicon steel sheet with high magnetic permeability. It is using full 45° slope lamination, so that the noload loss and the no-load current are reduced efficiently.
We use Simulating Analysis in the core model design, so that we can calculate the frequency and size of the vibration exactly and avoid the core cavity resonance.
Between core & windings, and core & frame, we use spring connection. Then the noise is lower 10 to 15dB than the standard.
