Market share of dry-type transformer

In the transformer market of our country, the share of dry-type transformer is still less. According to statistics, the application of dry-type transformer in large and medium-sized cities accounts for 15%-20% on average. In cities such as Beijing, Shanghai, Guangzhou and Shenzhen, it accounts for about 50% . However, the application of dry-type transformers in China's rural distribution networks is relatively rare, overall, dry-type transformers still account for only 10-15% of transformer applications.
　　
 

   In recent years, thanks to a large number of infrastructure investment and the rapid development of the power industry, the transformer industry has expanded rapidly in scale and capacity, but there are also problems such as low industry concentration and obsolete technology level. During the "Fifteen" period, the national strategic planning of Adjusting Energy Structure and building smart grid brought new development opportunities to the transformer industry. Dry-type transformer is being used more and more widely because of its excellent environmental protection, flame-retardant and anti-impact characteristics. The optimization and adjustment of China's energy structure has promoted the energy-saving transformer products to become the mainstream of the market and the future trend of development. Jiangsu Liwang Electric Equipment Co. , Ltd. , as a large-scale, strong technology production enterprises, for the product energy-saving performance research has been placed in the important position of enterprise development. Its energy-saving dry-type transformer with its excellent energy-saving performance for the industry to set an example. Liwang electric energy-saving dry-type transformers include energy efficiency two-stage and energy efficiency one-stage. The no-load loss of energy efficiency two-stage dry-type transformers is more than 20% lower than that of SCB10 products, the energy efficiency of the first-stage dry-type transformer is reduced by more than 30% , significantly saving the operating cost. In the noise level, the two types of energy-saving dry-type transformers are lower than the current professional standard JB/T10088-2016"6-220 KV transformer sound level" by more than 10-15 DB. In addition, the resin mixture of this type of energy-saving dry-type transformer adopts foreign advanced mixing method and vacuum membrane degassing technology to make the mixture mix evenly and eliminate the air bubbles in the mixture completely. The product only has the extremely low partial discharge quantity, may control under 5PC. Both high and low voltage coils are cast under vacuum and pressure, so that the resin insulation has both full envelopment and interturn soakability. The casting body has a compact curing structure, flame retardant, explosion-proof, not polluting the environment. In the polishing of product quality, Liwang Electric is also meticulous. The company advocates the idea of pursuing high quality with high quality and high standards, therefore, Liwang Electric has formulated a series of perfect product quality standards, and strict implementation. IN THE PROCESS OF R & D and production, the enterprise has also continuously increased its investment in technical force and modern equipment, all links from incoming inspection of raw materials, production, inspection of finished products, storage of finished products, storage of finished products to installation have been closely monitored, and unqualified products are never allowed to flow out, the pursuit of "zero defects" bit by bit into every detail, to ensure that each process layer by layer clearance, elaborate to create perfect products. The promotion of Liwang Electric energy-saving dry-type transformer provides an ideal energy-saving solution for distribution system of power station, factory, hospital, airport, tunnel, chemical plant, nuclear power station and other places and facilities. With the continuous expansion of the domestic dry-type transformer market, we believe that in the future Liwang electric energy-saving transformer will be able to continue to inject vitality into the market, the concept of energy conservation will be effectively promoted.
