VzimanElectric's Technology

Core:

• The core is made of high quality grain-oriented cold-rollled silicon steel of high magnetic conductivity, by using 45°five-step overlapping method to reduce the no-load loss and no-load current.
• Simulation analysis method is applied for the core design, thus to precisely and effectively calculate the vibration frequency and scale.
• Flexible connections are adopted between the core and coils, core and clamps. With these measures, transformer's noise level has been improved by 10-15dB over the conventional products.

LV Winding:

• LV windings are adopting superior foil conductors or made of 100% copper wire, thus to obtain better amperturn balance and reduce more transverse magnetic flux leakage. Then to greatly improves transformer's anti-short circuit capability.
• Excellent design of oil passage structure, greatly increasing the coils' heat dispersion effect. It helps to decrease temperature rise of the LV winding and improve transformers' overload capability.

Tank:

• The tank is jointed with highquality steel. The surface is eliminated rust phosphate coating and painted 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.
