According to data from Champ Consulting GroupIn 2023, the demand for flameproof transformers at home and abroad will increase. The main reasons are the following:

The recovery of the coal industry at home and abroad. Global coal production and consumption have declined in 2020 as a result of the neo-crown epidemic, but as the epidemic is brought under control and the economy recovers, the coal industry will gradually pick up from 2021, especially in Asia, where coal remains the main source of energy and demand for coal is high in countries such as China, India and Indonesia.According to data from the Shangpu Consulting Group, global coal demand will increase by 4.5 in 2021 to 7.7 billion tons, exceeding the level in 2019. In 2022, global coal demand continues to grow by 0.6 per cent to 7.74 billion tonnes. This means that the demand for mining electrical equipment such as explosion-proof transformers will also increase.

The promotion of energy conservation and emission reduction policies. In order to cope with the challenges of climate change and environmental pollution, a series of energy conservation and emission reduction policies and measures have been issued at home and abroad, requiring the coal industry to improve energy efficiency, reduce emissions and reduce waste. This requires mining explosion-proof transformers and other power equipment to improve performance and safety, reduce energy consumption and loss, to meet environmental standards. For example, the national standard "mine flameproof mobile substation"The technical requirements, test methods and inspection rules of the mobile substation and its components are specified, and the mobile substation is required to have good explosion-proof performance, insulation performance, load capacity, temperature rise limit, etc., and meet the relevant safety specifications.

impact of technological innovation and product upgrading. With the progress of science and technology and market competition, the mining explosion-proof transformer industry is also constantly carrying out technological innovation and product upgrading to improve product quality and technical level, meet the individual needs of customers, and enhance brand influence and competitiveness. For example, Shenyang Transformer Research Institute Co., Ltd.A temperature monitoring system for flameproof dry-type transformer based on intelligent sensor is developed, which can monitor the internal temperature of the transformer in real time and send it to the host computer or mobile phone through wireless transmission to realize remote monitoring and fault warning. Jiangsu Zhonglian Electric Co., Ltd.A flameproof dry-type transformer with oxygen-free copper foil winding technology is introduced, which can effectively reduce the temperature rise and loss of the winding, and improve the mechanical strength and impact resistance of the winding.

In summary, according to the projections of the Champ Consulting GroupIn 2023, the demand for flameproof transformers at home and abroad will increase. It is estimated that the domestic market demand will reach about 2 billion yuan in 2023, an increase of 8.1 percent over the same period last year, while the foreign market demand will reach about 1 billion yuan, an increase of 10 percent over the same period last year. Overall, the market demand for flameproof transformers will reach about 3 billion billion yuan in 2023, an increase of 8.7 percent over the same period last year.

In terms of market supply, the main domestic manufacturers include Shenyang Transformer Research Institute Co., Ltd., Jiangsu Zhonglian Electric Co., Ltd., Tonghua Transformer Manufacturing Co., Ltd., etc., with high product quality and technical level, and a large market share. According to the statistics of Shangpu Consulting Group, the top three enterprises in the domestic flameproof transformer market in 2022 are Shenyang Transformer Research Institute Co., Ltd., Jiangsu Zhonglian Electric Co., Ltd. and Tonghua Transformer Manufacturing Co., Ltd., with market shares of 22.3, 18.7 and 15.4, respectively. These companies not only have an advantage in the domestic market, but also actively explore overseas markets, using the "Belt and Road" initiative to cooperate with coal development countries in Asia, Africa and other regions to increase exports. According to Chinese customs statistics, from January to November 2022, China's exports of flameproof transformers reached 0.32 billion billion yuan, an increase of 12.8 percent over the same period last year, with the main export destinations being India, Indonesia, Vietnam, South Africa and other countries.

In terms of development prospects, Shangpu Consulting believes that the mining explosion-proof transformer industry is still facing some challenges and opportunities. The challenges mainly come from the following aspects:

The market competition is fierce. With the growth of market demand, domestic and foreign production enterprises are also increasing, resulting in intensified market competition. On the one hand, the competition among domestic enterprises is becoming increasingly fierce, the homogenization of products is serious, the price war is frequent, and the profit space is squeezed. On the other hand, foreign companies are also constantly entering the Chinese market, using their technological advantages and brand influence to seize market share. For example, Siemens of Germany, Schneider Electric of France and Toshiba of Japan are all well-known enterprises in the field of flameproof transformers, and their products enjoy high reputation and recognition in the international market.

Increased environmental standards. In order to protect the environment and personnel safety, the national environmental protection standards and safety specifications for mining flameproof transformers and other power equipment have been continuously improved, requiring enterprises to strictly control pollutant emissions and noise levels in the production process, and take into account energy saving and emission reduction in product design. And safety protection and other factors. This requires enterprises to invest more capital and manpower for technological transformation and equipment renewal to meet policy requirements and market demand.

New energy replacement. With the development of new energy technology and the reduction of cost, such as wind energy, solar energy, nuclear energy, more and more countries and regions begin to use new energy instead of traditional energy, in order to reduce the dependence and consumption of fossil energy such as coal. This means that the demand for the coal industry and its related equipment will gradually decrease. The European Union, for example, has developed a European Climate Act aimed at achieving carbon neutrality by 2050 and phasing out high-carbon energy sources such as coal.

Opportunities mainly come from the following aspects:

technological innovation and product differentiation. Facing the challenge of market competition and environmental protection standards, enterprises can improve their core competitiveness and market share through technological innovation and product differentiation. For example, more efficient, energy-saving, safer and smarter explosion-proof transformer products can be developed to meet the individual needs and high-end needs of customers. New technologies such as the Internet of Things, big data, and artificial intelligence can be used to realize the functions of remote monitoring, fault diagnosis, and intelligent adjustment of flameproof transformers to improve the reliability and convenience of products. New materials, new processes, new structures, etc. can be used to reduce the weight and volume of the product and improve the performance and life of the product.

Expand new application areas and market space. In addition to the application of coal mines, explosion-proof transformers can also be used in other places with explosion hazards, such as petrochemical, metallurgy, medicine and other industries, to provide power for various equipment and instruments. This opens up new application areas and market space for flameproof transformers. At the same time, explosion-proof transformers can also use the "Belt and Road" initiative to strengthen cooperation with countries and regions along the route, expand overseas markets, and increase exports. Especially in Asia, Africa and other regions, due to the rich coal resources and the low level of coal development, there is a large demand for power equipment such as flameproof transformers.

Enhance brand influence and competitiveness. Through technological innovation and product differentiation, companies can improve their brand influence and competitiveness, increase customer trust and loyalty, and expand market share. At the same time, enterprises can also enhance their industry status and sense of social responsibility by strengthening publicity and promotion, participating in the formulation of industry standards, and joining industry associations, and enhance communication and cooperation with the government, industry, customers and other parties.

In short, the supply and demand analysis and development prospects of the mining explosion-proof transformer market in 2023 show that the industry still has great development potential and space, but it also faces some challenges and opportunities. It is suggested that enterprises should strengthen technological innovation and product differentiation, improve product performance and safety, reduce cost and energy consumption, expand new application fields and market space, and enhance brand influence and competitiveness according to market changes and customer needs.
