We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for dry type transformer. The core is made of cold-rolled grain-oriented silicon steel sheet which cut in step-lap by GEORG Germany TBA core cutting lines and laminated by the method of fifth-order step-by-step stacking technology, enabling the no-load performance of the core to improve greatly. The epoxy resin from American HUNTSMAN is adopted for the windings which casted in the vacuum resin casting machine imported from HEDRICH, Germany. The winding material ensures good permeability, no bubbles occur, which leads to minimum partial discharge. The HV and LV winding mate with each other tightly, which ensures solid strength of structure and capability to withstand short circuit and vibration. Under normal service condition, the service life of dry type transformer is 30 years. No crack will form on the surface of transformer winding due to temperature variation as long as the transformer runs under normal service condition.

Power management semiconductors are critical to ensure the stable operation of electronic systems. The decline in the market's growth rate this year is mainly due to the influence of two factors. Many semiconductor factories are located in Japan, and the March earthquake caused disruption of production in some parts of the country and the power management semiconductor market slowed down. By September, the situation in Japan had basically returned to normal, but the power management semiconductor market faced another problem immediately - consumer spending began to decline from the middle of the year. IHS believes that consumer spending may not begin to improve until the second half of 2012.
In the third quarter, consumer tightening expenditures have led to a slowdown in revenue growth in the power management semiconductor market, which was a growth rate of only 2.3% from the previous quarter, compared to 8.8% in the third quarter of last year. Forecasts show that the market's demand for popular consumer electronic products such as mobile phones and mobile computing devices has decreased, so it is expected that the situation will not improve in the fourth quarter. Mobile phones and mobile computing devices are two major factors driving the growth of the power management semiconductor industry.
2011 Power Management Semiconductor Revenue $331
Insufficient consumer purchasing power and the strong impact of the March earthquake in Japan on the supply chain, the development trend of the power management semiconductor market in 2011 was not as expected 2011 power management semiconductor operating revenue is expected to be 33.1 billion US dollars, an increase of 6.7% from 2010's 31 billion US dollars The growth rate is far lower than the 37.8% in 2010. The market is expected to grow slightly by 3.9% to reach 34.4 billion U.S. dollars next year.
