After more than 50 years of development, China's insulating material industry has initially formed an industrial system with relatively complete products, complete supporting facilities, and considerable production scale and scientific research strength. Especially in the 21st century, with the rapid growth of the national economy, the rapid development of the power generation, transformation, and electrical machinery industries, it has promoted China's domestic demanding insulation material market. At present, some products have reached a high level, have strong competitiveness in the international market, and became the world's largest producer of insulation materials in the late tenth century.


During the Eleventh Five-Year Period (2006-2010) in the early 21st century, the installed capacity of China's power generation equipment increased year by year at a rate of about 10, and the rapid development of household appliances and railway construction has given China's insulating material industry, especially the insulation layer. Compressed materials, etc. provide a larger space and market for development. During this period, the output of environmentally-friendly, energy-saving and high-performance products has grown rapidly. A number of new-type enterprises have made new improvements in both production scale and manufacturing technology. Insulation materials are widely used in many fields such as electrical appliances, electronic information, automobiles and aerospace. In recent years, the innovative application of insulating materials has gradually become one of the key driving forces for the implementation of sustainable energy solutions in China, and the country attaches great importance to the development of insulating materials.


First of all, in the "Outline of National Medium- and Long-term Scientific and Technological Development Planning (2006-2020)" promulgated in China in recent years: focus on research and development of high-performance composite materials and large and ultra-large composite structural components that meet the needs of the development of the basic industries of the national economy. Preparation technology, which also shows that the development of high-performance composite materials in China has been listed as the priority topic of basic materials in the manufacturing industry in China. Secondly, the "Industrial Structure Adjustment Guidance Catalogue (2005 edition)" issued by the National Development and Reform Commission lists composite materials and functional polymer materials as industries encouraged by the state. In addition, the Ministry of Industry and Information Technology proposed in the China's Twelfth Five-Year Plan for the Development of Raw Materials in January 2011 that the new materials industry is the leader of the development of the materials industry and an important strategic emerging industry. Accelerating the cultivation and development of new materials industries has important strategic significance for supporting the development of strategic emerging industries, ensuring the construction of major national projects, promoting the transformation and upgrading of traditional industries, and building new international competitive advantages. The extensive application of electrical equipment has brought broad development space for new materials: In recent years, driven by the strong demand for electricity, China's electrical equipment industry has entered a period of ultra-high growth, not only in size but also in technology. The industry is also facing rare development opportunities. Recently, China's energy conservation and environmental protection requirements have brought huge opportunities for energy conservation and consumption reduction products in the electrical equipment industry.


With the coming of a new round of power investment boom, power transmission and transformation equipment manufacturing enterprises will be at full capacity in the next few years, showing a booming production and sales situation. However, the reliability and service life of core equipment such as transformers depend to a large extent on the resin substrate / molding material used. In addition to the performance requirements of the laminates used in transformers, in addition to the conventional requirements of mechanical strength, electrical properties, good heat and moisture resistance, and good machinability, in recent years, in order to ensure that transformers are more reliable in operation, Good reliability has higher requirements for its heat resistance and arc extinguishing under high pressure. For resin-based reinforced composite material manufacturing enterprises, the rapid growth of power transmission and distribution equipment and other industries has injected a strong impetus into the development of the entire industry. The rapid development of rail transit construction has ensured the strong demand for new materials: According to the National Medium and Long-term Railway Network Plan, by 2020, the national railway operating mileage will reach 100,000 kilometers, and the main busy trunk lines will achieve passenger and freight separation, and the double line rate and The electrification rate has reached 50, the transportation capacity can meet the needs of national economic and social development, and the main technical equipment has reached or approached the international advanced level. In addition, in recent years, about 1.8 trillion yuan of infrastructure investment plans issued by the state will be invested in railways, highways, airports, and major infrastructure construction, of which railway investment is about 500 to 600 billion yuan.


With the acceleration of railway electrification, the new materials market will also grow rapidly. From the perspective of the entire insulation material industry, developed countries such as the United States, Germany, and Switzerland have developed earlier, and the technology of insulation material products is at the world-leading level. At present, the large companies in the insulation material industry in the world are mainly concentrated in the United States, Switzerland, Austria, Germany, Countries such as Japan and the United Kingdom occupy the vast majority of the international market. In recent years, China's domestic insulation material industry has developed rapidly in recent years, especially compared with foreign manufacturers, there are obvious cost advantages. With the continuous improvement of the technical level of domestic insulating material production enterprises, their share in the international market is increasing, and the competitiveness of the international market is gradually increasing. Worldwide, manufacturers of laminated (molded) insulation materials are mainly manufacturers of insulating laminates. Most of them are comprehensive chemical and chemical production plants, with strong technical level and financial strength. The basic situation of the major foreign insulating laminate companies is shown in the table below. These companies are at the forefront of the world in terms of material manufacturing technology, production equipment, customer quality, and service level. Therefore, to improve the technical level of domestic GPO-3 board manufacturing, It has become a very important task for domestic GPO-3 board manufacturers.


According to survey statistics, there are currently about 60 companies in China that have the ability to manufacture laminated insulation materials, and that the production can run normally and the annual output can reach more than 200 tons. Among them, there are 12 enterprises with an annual actual output of 1,500 tons. Their total output in 2010 accounted for 72% of the total production of laminated insulation materials in China. The total sales of 12 laminated insulation materials accounted for about 74% of the total sales of such products in China. The actual production statistics in 2010 are shown in the table below. With the high voltage and high current of China's electrical equipment, fire protection requirements for layer-molded insulation materials, as well as requirements for high voltage resistance and high strength, have increased the demand for personalized materials, requiring manufacturers to provide insulation. While stabilizing the production capacity of materials, it forms a development model with its own characteristics. Therefore, the layered insulation material market is fully subdivided, and companies are inclined to specialize in target markets. At the same time, companies that provide customers with overall solutions based on their technical strength have obvious competitive advantages.


Currently. The laminated insulation products produced by the issuer have entered CSR, CNR, Siemens, Toshiba, Hitachi, GM, Alstom, Schneider and others. And as customers' requirements for supporting manufacturers continue to increase, the issuer has the ability to develop, design and finish insulation systems, and has become a leading supplier of complete system solutions in the insulation field.
