A gift to the 70th anniversary of the motherland

——Haihong's technological innovation bears fruit again

　　2019 is the 70th anniversary of the founding of the People's Republic of China. Time flies, and 70 years is but a blink of an eye. But for the Chinese nation, which has experienced countless trials and tribulations, seventy years is enough to open up the world and create brilliance! The great achievements of the Chinese nation in the past 70 years of development depend on "rejuvenating the country through hard work". Industry is the foundation of a country and the foundation of a strong country.

　　New China's manufacturing industry has grown from scratch, from weak to strong, especially since the reform and opening up, "Made in China" has experienced rapid development and has made great contributions to the Chinese economy and even the world economy. But behind the halo, "Made in China" has also encountered unprecedented crises and challenges. We will accelerate industrial transformation and upgrading, increase independent innovation and research and development, improve the overall quality of products, create a number of outstanding national brands, and realize "Made in China". Quality development is a top priority.

　　Since its establishment, Haihong Electric has deeply realized that innovation is the foundation of enterprise development, and it must firmly grasp the commanding heights of technology in order to take the lead in the fierce market competition. Haihong has insisted on innovation and investment for 20 years, independently developed green and energy-saving three-dimensional wound core transformers, and successively developed three open-type three-dimensional wound core transformers, amorphous alloy three-dimensional wound core transformers, and 110kV voltage level three-dimensional wound core power transformers. A series of world-leading products in technology.

　　On the occasion of the 70th anniversary of the motherland's birthday, Haihong's research and development has yielded fruitful results, presenting a gift to the motherland. Recently, Haihong has developed three new products super class 1 energy efficiency open three-dimensional wound core dry-type transformer, outdoor open three-dimensional wound core dry-type transformer, and miniaturized double-layer prefabricated substation。

1. Super Class 1 open three-dimensional wound core dry-type transformer

　　When the load rate is higher than 50%, the performance is better than that of the amorphous alloy transformer, and the cost performance is better than the mainstream products in the current market. It has significant advantages such as low no-load and load loss, low noise, and strong short-circuit resistance. It is suitable for data Power transmission and distribution environments with high energy-saving requirements such as centers, rail transit, airport projects, and government projects.

2. Outdoor open ventilated 3D wound core dry-type transformer

　　Combining the characteristics of open three-dimensional wound core dry-type transformers with fire and explosion protection, moisture resistance and pollution resistance, and strong weather resistance, the outdoor open three-dimensional wound core dry-type transformer developed by NOMEX^?Insulating paper + Alentas insulating varnish are the main insulating materials, combined with the innovative box design, the product can operate safely and reliably in complex and changeable outdoor environments, and can be directly used in outdoor places to overcome the easy occurrence of oil-immersed transformers. Oil leakage, oil leakage, rust and other problems, reduce the daily maintenance of transformers, and prevent combustion and explosion accidents caused by product failures. It can replace the current oil substations in urban and rural areas and streets, and has many advantages in performance, production cost, and economical use.

3. Miniaturized double-layer prefabricated substation

　　It perfectly solves the problem of shortage of land resources, has the advantages of reducing the occupied area of substations, compact structure, safe and reliable, low loss, low noise, strong short-circuit resistance, easy installation and use, maintenance-free or less maintenance, and is in harmony with the surrounding environment specialty.

　　The double-layer layout design occupies an area smaller than the conventional prefabricated substation (European Transformer) with the same schemereduce 44.7%，体积reduce 41.4%；Compared with the combined transformer (Meibian) of the conventional low-voltage cabinet scheme, the footprint is reduced18.2%。The roof adopts a double-layer roof pavilion structure, compared with the ordinary single-layer roof, the double-layer roof pavilion structureIt can reduce the temperature rise of the product by 10°C.The shell adopts enhanced ventilation structure, to ensure that the product has good ventilation and heat dissipation performance.

　　Every colleague is the fulcrum of Haihong's development. Haihong's R & D achievements today are due to the efforts of Haihong's team. In the future, Haihong will not forget the original intention, forge ahead, continue to increase product innovation, focus on product quality, and contribute Haihong's strength to promote the high-quality development of China's economy.
