We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for33kV cast resin 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.

In the first half of 2012, due to the sluggish economic situation, real estate control, and the overall tight monetary policy, China's commercial air-conditioning industry continued to slow down based on the slowdown in the second half of 2011.
Previously, due to the shrinking of the home air conditioner market, many companies have proposed plans to increase the number of betting commercial products. From the current situation, the growth of the commercial air-conditioning market is not as expected, and air-conditioning companies have hoped that the commercial market will not be able to make up for the home market. From the overall situation in the first half of the year, the industry still faces many challenges in the second half of the year. However, with the loosening of policies and the strategic adjustment of brands in the second half of the year, the overall downturn in the commercial air-conditioning industry may change.
Analysis of the Overall Market Scale of Commercial Air Conditioning in China
Recently, according to Ovid Consulting's monitoring data, the total market size of commercial air conditioners in China in the first half of 2012 was approximately 24.7 billion yuan, a decrease of 11.3% from the same period of 2011, and the decline was the highest in history.
