PRODUCTS 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-step overlapping method to reduce the no-load loss and no-load current.
2. Simulation analysis method is applied for the core design, thus to precisely and effectively calculate the vibration frequency and scale.
3. 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.
Transformer 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. 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.
2. 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.
ADVANTAGE:
1. Low loss, low noise, low partial discharge.
2. Strong anti-short circuit capability and high anti-lightning impact level.
3. Excellent moisture resistance for operation at 100% relative humidity.
4. Strong overload capability for long-term operation at 150% loading.
