      sensor manufacturing industry both opportunities and challenges
      ????With the new round of investment boom coming of electricity, power transmission equipment manufacturing enterprises in the coming years will be in full load condition, showing sales booming, very boom situation. As the transmission and distribution industry is an important branch of the sensor manufacturing industry is singing along. Since China from west to east, north and south mutually supplies, the national implementation of networking, sensor demand will remain steady growth.
      Generally speaking, China's power sensor technology is still in the early 1990s the international level, a small amount of a world 20 level of the late 1990s, compared with foreign advanced Countries, there is still a gap.
      Opportunities and challenges
      Countries in accordance with the electricity sector investment, "fifteen" plan, China from 2004 to 2005 will add installed capacity of 25 million kilowatts, the average annual investment in power construction in about 240 billion yuan, an increase of about 40% of investment, including power plant equipment the proportion of about 50% to 60%; the proportion of investment in network equipment is about 30% to 40%. Plus the State Council approved a total investment of 51.2 billion yuan of 13 new power plant power plant construction project, is expected to drive annual demand sensor industry is 3.6 billion to 400 million KVA.
      According to the statistics show that in 2003 in the power transmission industry, only the sensor industry average sales growth of more than 30% of total industry profit growth will reach 40%. However, the high growth in production does not mean that there is a high profit.
      At present, China's sensor market has been the emergence of signs of oversupply, price competition is increasingly fierce and cruel. This sensor enterprises from home and abroad can be seen by low profit margins. Take dry-typeCurrent and voltage, the 1995 average profit margin of 22%, due to the influx of production companies, six years later it had dropped to about 5%, and as steel, copper and other raw materials prices continue to rise, and the sensor industry not because the market is good to sit back and relax. Now, dry-typeCurrent and voltage because excess capacity, it has been included in the list of restrictions on the development.
      Only the country's sensor business, more than 100 in 1995, and the end of 2003 the industry has grown to more than 1,000. 500 kilovolt sensor market was slightly better than the high-end price competition primarily from lower than differences and marketing strategy, and a number of low-end sensor manufacturers, the market markedly confusion, there is no shortage of low-cost distribution possible. As competition has intensified among the manufacturers, the future is only 20 to 30 companies may occupy most of the sensor market.
      Some large multinational companies into possession of 20% to 30% of the sensor market, and with its advanced technology, abundant capital and brand in the expanding market share, which gives a huge impact on domestic enterprises. In order to be able to win a share of the market, many sensor manufacturers from abroad advanced production technology and equipment, in order to further improve the product mix, improve product performance, new technology, exploration of new materials have made unremitting efforts to meet the needs of the development of the sensor.
      US exports of 900MVA sensor
      TBEA is a perfect example. Recently, TBEA Shenyang sensor Group production of China's first official US exports of 900MVA sensor and network operation in Los Angeles MEW Simma (sylmar) power plant, now everything is normal indicators, running in good condition. As Ye Jun, general manager said, we will be under the background of global economic integration, active use of international resources, the spirit of "bringing in and going out" purposes, and actively introduce with the world's outstanding business and management and operation mechanism mechanism to attract and gather more international and domestic outstanding experts, talent, especially to strengthen technical cooperation in the field of technology and innovation to further enhance the capacity of enterprises, enhance the core competitiveness of enterprises to produce more world-class product .
      Product development direction
      1 large ultrahigh voltage level to the voltage level of development will 750kV, 1000kV development. The high cost has been the biggest obstacle to the market superconducting sensor, superconducting sensor superconducting material costs account for 70% to 80%. According to Wang Yinshun researcher, the superconducting material is used PIT process, the experts currently being developed by spraying technology second generation superconducting materials. This will improve the mechanical properties, thermal properties of superconducting material, while greatly reducing the cost of materials, thereby allowing superconducting sensor from technology to shorten time to market.
      2 energy saving, Miniturization, low noise, high impedance, explosion-proof development of such products to small or medium size, as is currently the urban and rural power grids are recommended new S9-type distributionCurrent and voltage; and the volume of iron core sensor, amorphous alloyCurrent and voltage, sealedCurrent and voltage, the combination ofCurrent and voltage, dry-typeCurrent and voltage, high flash point oilCurrent and voltage, SF6 gas-insulatedCurrent and voltage. China will study the introduction of preferential policies to encourage the replacement and renovation of old high-energyCurrent and voltage, develop and promote the production and sales ofCurrent and voltage, to encourage the promotion of efficient sensor.
      In summary, our sensor business should be clearly aware of where the opportunities and challenges. Expedite the development of test methods and conditions, mainly refers to the partial discharge test should be shielded specialized laboratory, so as to make the test data reliability, it is the product competitive. According to the Investment of development and high voltageCurrent and voltage, high-capacity sensor, recommendations for industry management and standards committee work in time to revise the existing standard.
      Enterprises should seize this historic opportunity to meet new challenges: Restart information technology, revolutionizing the old enterprise management system and embarked on the path of development and the new international standards. Companies must expand the scale of production capacity, in order to ensure the sound development of the business into the fast lane.
