Metal-enclosed bus is one of the main products of our plant. Since 1978 the first set of metal-enclosed bus was successfully developed, we have designed and manufactured more than 1000 sets of metal-enclosed bus and its associated facility for hydro, coal and nuclear power generating plants home and abroad. The products have been operating well, and some even more than 30 years. Practice shows that our products have the characteristics of installed conveniently, operated safely and quality reliably.
Our products have been identified by the Ministry of Electric Power and then started to produce in 1986. Meanwhile, we drafted the state's existing "Metal-enclosed Bus" National Standards (GB/T8349-2000) consigned by the National Bureau of Standards .Due to excellent product design and reliable operation, our products were awarded as Beijing quality products and national quality products in 1987,and were recommended consistently by the Ministry of Electric Power as the preferred China manufacturer of metal-enclosed bus for many years.
Metal-enclosed bus works is a branch plant of BPEG which specialized produces various types of metal-enclosed bus including more than 20 qualified professional designers who have rich experience in designing and manufacturing processes. We attach great importance to the products quality. Every designer owns one computer and makes full use of CAD (computer aid design) in designing to ensure the quality. We adopted vacuum ion silvering technology, effectively reducing the temperature rise of contact face. The introduction of the state-of-the-art automatic protection soldering machine and digital rolling machine ensured the quality of the rolling and soldering. Now we have two production lines, making the annual production capacity reached to more than 100 sets.
Through long-term design, practice and new product development, our product pattern ranges from 12~1750MW units with a variety of metal-enclosed bus, such as continuous and noncontinuous enclosure type isolated-phase bus, self-cooling and force-cooling isolated-phase bus, micro-pressure air-charging isolated-phase bus, non-segregated and segregated phase common enclosure bus which can apply to different sizes and patterns .
In recent 30 years, we have supplied more than 1000 sets of metal-enclosed bus for various unit capacities, of which for the first-phase 310MW and second-phase 2×600MW of Qinshan Nuclear Power Plant have operated well. Haerbin No. 3 Power Plant and Datang Panshan Power Plant 3×600MW units have been generating electricity, Ertan Hydro Power Plant 6×550MW units have also been operating well. On Aug. 2nd, 2010, we made a contract with Alstom Technical Service Limited Company for the Guangzhou Taishan Nuclear 2X1750MW Project which has the biggest single machine capacity and rated current reaches to 44,000A. Until now, BPEG has become the first-rate manufacturer of Mental Enclosed Busduct，which has designed and manufactured the biggest hydro, coal and nuclear power project in China. Our products have entered the international market and have exported to Nepal, Pakistan, Malaysia, Canada, India, Indonesia, Turkey and other countries. We also have established a experienced team for users with high quality after-sale services, to ensure that the metal-enclosed bus could be installed and debugged smoothly, which won widely users' praise.
With socialist market economic system getting further improved and state-owned enterprises becoming deeply reformed, we are also planning to meet the requirements of the situation, deepening on the reform and renovating concepts. We welcome friends of all circles and foreign countries to the plant to visit and inspect. Ensuring the provision of quality products and quality services to customers, we would like to provide our friends with more outstanding products and higher quality service.
