The 14th Five-Year Plan period is the key period and window period of carbon peaking. In the face of the new situation and new tasks, Tianjin TBEA Transformer Company Limited (hereinafter referred to as "Tianbian") has anchored on the national goal of "carbon peaking and carbon neutrality", based on the advantages of resource endowment of Tianjin, firmly seized the opportunity of new energy development, accelerated the market structure adjustment, and made a combination with the different new energy generation scenarios such as offshore, land, Gobi and desert, and completed the research and development of the whole series of products and launched them into the market successively at the fastest speed. Up to present, the Company has provided nearly 4,000 sets of green energy-saving transformer products, including dry-type transformers inside the wind turbine cabin, water-cooled transformers inside the tower, integrated photovoltaic power generation box and inverter, integrated energy storage box and transformer, etc. to the coastal areas of East China and Northeast China, so as to form a new ecology of green low-carbon recycling industry chain development.

　　Wind Turbine Cabin Transformers

　　Wind power, as a clean and renewable energy source, has been growing rapidly around the world. Tianbian Transformer has been closely following the market demand, and has organized a special research team to develop a dry-type transformer inside the wind turbine cabin to improve the overall reliability and economy of power transmission and save investment cost. It features the advantages of local voltage boosting transmission, reduced tower load and transmission cable line loss, etc. and has passed Italy's CESI vibration test, Spain's harsh LCOE trial run test, and received Germany's TUV certification, so that it can satisfy the energy efficiency level of the latest EU standard in July 2021 and can guarantee long-term safe and reliable operation. The development of dry-type transformer inside the wind turbine cabin has broken the "bottleneck" technology, solved the problem of localization of core technology, which is a comprehensive replacement of imported products.

　　Water-cooled Transformer in Tower

　　The water-cooled transformer in tower is another powerful product developed by Tianbian Transformer for the operating environment of high humidity and high salt density at sea. The product is a transformer embedded in the wind power generator with a fully enclosed shell protection and heat dissipation through water cooling radiator to the outside world, meanwhile the design can reduce the overall volume of the transformer to enhance the overall transmission reliability and save the maintenance cost later. The water-cooled transformer in tower can satisfy the offshore C5H anti-corrosion level, covering the mainstream wind turbine models such as 6 to 8 MW.

　　PV Power Generation Box Inverter All-in-One Machine

　　Furthermore, the integrated PV power generation box inverter developed by Tianbian Transformer is highly intelligent and can address complex and changing product application scenarios, providing customers with energy-saving, carbon-reducing and intelligent solutions. The equipment features the functions such as high mechanical strength, flame retardant, moisture-proof and sand-proof, and can fully adapt to the complex external environment. Meanwhile, the product also has an integrated step-up transformer and inverter, improving safety and reliability as well as saving more than 15% of cost.

　　Energy Storage Box Transformer Integrated Machine

　　To guarantee green electric energy storage, Tianbian Transformer has developed an all-in-one energy storage box and transformer, which has integrated transformer, high and low voltage cabinets, converter and other components, featuring large capacity, high integration and convenient on-site construction. High-grade dustproof design is applied to form an excellent barrier against wind and sand. The unique design of ventilation and heat dissipation system can finely control the temperature of the cabinet and improve the stability of product operation, and the overall technical index is at the domestic advanced level.

　　National Specialized, Precise, Special and Innovative "Small Giant" Enterprise, National Green Factory, Tianjin Manufacturing Single Champion Cultivating Enterprises ...... Since it was settled in Tianjin Port Free Trade Zone in 2009, Tianbian Transformer has been making continuous progress with great achievements, and now it has become a backbone enterprise in the national dry-type transformer industry. Nurtured by the excellent business environment and fertile soil, the Company has continued to invest in Free Trade Zone, centered on the national "carbon peaking and carbon neutrality" target and the development of new energy, smart grid and smart city construction. With the integration of design and manufacturing, warehouse and logistics, as well as quality standard detection and control, it aims to create a digital demonstration factory with the integration of information technology and automation, to realize end-to-end process management from design, production to service and networked and intelligent manufacturing with information and physical integration, and to contribute to the national "carbon peaking and carbon neutrality" target and green development while contributing to the high-quality development of Tianjin Port Free Trade Zone.

　　In recent years, Tianjin Port Free Trade Zone has actively put into practice the national green development policies, continuously improved the construction of green manufacturing system, and actively promoted the regional green governance and the green development of enterprises as the primary task while enhancing the manufacturing capacity. In the future, Free Trade Zone will continue to take "carbon peaking and carbon neutrality" as the guideline and continue to build a green manufacturing system. Meanwhile, Free Trade Zone will seize the opportunity of digital economy development, actively promote the deep integration of new technologies and modes such as Internet and artificial intelligence with various fields of economy and society, make the best use of data integration and platform empowerment in promoting the digital transformation of industries, and demonstrate the bonded status in building a new pattern of digital development in Tianjin.
