From 65438 to 0997, at the beginning of Shenma's establishment, enterprises closely focused on the oil leakage problem of power transmission and transformation equipment that plagued the power industry for more than half a century, and developed acrylate seals with the same service life as the equipment through independent technological innovation, which solved this long-standing problem in one fell swoop. At present, the domestic market share exceeds 80%. The product technology fills the domestic blank, and the enterprise dominates the formulation of industry standards.
Relying on independent technological innovation, the hollow composite insulator is developed to fill the international gap.
In 2000, Shenma discovered the explosion injury and pollution flashover of traditional porcelain hollow insulators that have plagued the power industry for more than half a century. What is more serious is that the core components of hollow insulators above EHV level in China are completely dependent on imports and have long been controlled by people. Shenma has developed a hollow composite insulator to fill the international gap through independent technological innovation, adopting new technologies, new materials and new processes, effectively putting an end to all kinds of accidents of traditional porcelain hollow insulators. More than 50,000 Shenma hollow composite products with voltage levels of 65,438+065,438+000 kV-65,438+0,000 kV have been widely used all over the world, and no safety accidents have occurred, which has reduced the huge accident losses for the power grid. The successful development of Shenma hollow composite insulator has not only completely broken the long-term international monopoly of hollow insulators above ultra-high voltage level in China, but also led the international in comprehensive performance, and enterprises have also become the main units in formulating national standards for this product.
The successful development of Shenma hollow composite insulator has also greatly promoted the development of China's power equipment manufacturing industry. It turns out that 500 kV SF6 transformers all depend on foreign manufacturers, and domestic enterprises can no longer produce independently. After the application of Shenma hollow composite insulator, high-end transformer products with independent intellectual property rights have developed rapidly in China. At present, China's 500 kV SF6 transformer products have been completely self-sufficient, and all these products use Shenma hollow composite insulators.
Relying on independent technological innovation, the pillar composite insulator is developed to fill the international gap.
In 2005, Shenma developed the pillar composite insulator with the technology to fill the international gap, and the product performance reached the international leading level, which put an end to the hidden dangers of pollution flashover, damage and collapse of traditional porcelain pillar insulators, and once again broke the long-term international monopoly on China.
Relying on independent technological innovation, a full range of composite insulators for AC and DC lines have been developed.
In 2007, in order to further improve the technology and cost performance of China's line composite insulators, Shenma high-point positioning took one year to develop a full range of AC and DC line composite insulators, and the product material properties and process level reached the international leading level. In March 2009, Shenma successfully won the bid for the 800 kV HVDC "Xiangjiaba-Shanghai" transmission project of State Grid Corporation, and its products were applied to UHVDC projects in batches.
Relying on independent technological innovation, a full range of electrical bushings have been developed.
In 2009, in order to better create value for customers and provide customers with products with good quality, low cost and short delivery time, Shenma successfully developed11000 kV-1000 kV full series SF6 switch electrical bushing, which filled the international gap and reached the international leading level.
Relying on independent technological innovation to strongly support the construction of national UHV power grid
In the demonstration stage of UHV AC 1000 kV power transmission and transformation project, experts pointed out that external insulation is one of the technical bottlenecks restricting the smooth progress of the project-the international technology may not be mature, and the price of each foreign porcelain hollow insulator is as high as 4 million yuan. On the basis of Shenma raising 50 million yuan independently, the National Development and Reform Commission has invested130,000 yuan in the central budget for the research and development of UHV hollow composite insulators. After Shenma successfully developed UHV AC 1000 kV hollow composite insulator to fill the international gap, the price of foreign companies dropped to 2 million yuan/piece, while the price of Shenma products was only 680,000 yuan/piece. More importantly, the performance of the product in actual operation has completely surpassed that of foreign products and reached the international leading level. At the same time, the UHVDC 800 kV pillar composite insulator independently developed by Shenma has been applied in the UHVAC 800 kV Yunguang transmission project of China Southern Power Grid Corporation, and its product performance has reached the international leading level, which has been highly praised by experts from Siemens Group of Germany.
Shenma composite insulator products have successfully withstood the test of two extreme natural disasters.
In 2008, a large number of porcelain insulators were covered with ice, flashover, fracture and collapse during the freezing rain and snow disaster in southern China and the 5. 12 Wenchuan earthquake disaster, which was one of the main reasons leading to power grid paralysis. All products operated by Shenma in the disaster area are safe and accident-free, effectively supporting disaster relief and post-disaster reconstruction.
The technological breakthrough made China become a global leader in the field of external insulation of power grid from a backward chaser.
Shenma composite products not only serve the development of domestic power grid, but also serve the development of global power grid. More than 80% power transmission and transformation equipment manufacturers in the world actively seek cooperation, and ABB, Siemens and Areva have formed long-term strategic cooperative relations with Shenma. Now, almost all users in the world have this understanding: the products with the best performance in the world can be bought at the most favorable price, which comes from the creation of China Shenma! The creation of Shenma will never stop, not only contributing to the development of China industry, but also to the global industry, which belongs to the value of China enterprises. Facts have proved that China's development is a contribution to the world, not a threat.
