Shenma Power Station, founded in 1996, is the largest composite insulator manufacturer in China (according to the data of Swedish ABB 20 1 1, Shenma Power Station's world market share has far surpassed Tyco, McLean, MR and other European competitors, becoming the largest composite insulator manufacturer in the world).
Relying on independent technological innovation, the company has developed power transmission and transformation seals to fill domestic gaps and hollow composite insulators, pillar composite insulators and composite insulating sleeves to fill international gaps. These products have applied for 54 national patents and successfully applied for international invention patents in 2/kloc-0 countries around the world. At the same time, the company has also become the main formulation unit of national standards for these products.
In 2000, Shenma discovered the problems of explosion 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.
