Transformer industry hot spotlight

I. Intelligent power protection to help modernise the tea industry

Recently, Guizhou Dejiang Power Supply Bureau installed a 160 kVA transformer for local tea processing enterprises, solving the pain point of insufficient power supply in the traditional tea-making process. After the new transformer was put into operation, the tea factory's intelligent equipment achieved full load operation, including intelligent picking robots, automated processing production lines and IoT management systems, increasing tea processing efficiency by more than 50% and significantly enhancing quality stability.1 This case highlights the key role of power infrastructure upgrades in the digital transformation of traditional industries, and also provides a good example of how to modernise the tea industry for tea enterprises nationwide. This case highlights the key role of power infrastructure upgrading in the digital transformation of traditional industries, and provides a model for tea enterprises across the country to demonstrate ‘intelligent production + stable power supply’.

During the same period, power grid enterprises in many places accelerated the replacement of old transformers. For example, a city substation has improved the reliability of regional power supply by replacing overloaded main transformers, laying out a plan in advance to cope with the summer power peak. Such projects generally use modular construction technology, combined with big data prediction of equipment life, to achieve the power grid operation and maintenance from ‘passive repair’ to ‘active prevention’ of the change2.

Second, the transformer recycling industry into the normative fast track

With the deepening of the ‘double carbon’ goal, Beijing Fengtai, Shijingshan and other areas of the recent intensive introduction of transformer recycling policy, requiring the establishment of a full life cycle traceability system, standardise the dismantling process and the promotion of environmentally friendly treatment technologies. The policy clearly requires: by the end of 2025, the waste transformer copper, iron and other materials recovery rate must reach more than 95%, the harmless treatment rate of insulating oil to achieve 100%.37 At present, the head of the enterprise has been introduced into the automated dismantling line and plasma cracking technology, a single transformer recycling time shortened by 40%, pollutant emissions reduced by 70%, to promote the industry to the intensification of the green direction upgrading, Green direction of upgrading the industry.

Third, technological innovation drive industry pattern reshaping

Transformer market in 2025 presents two major trends:

Intelligent product demand surge: equipped with sensors and edge computing module smart transformer accounted for more than 30%, can real-time monitoring temperature rise, load factor and other parameters, and through the AI algorithm to predict the failure, operation and maintenance costs reduced by 25%.

New energy-adapted equipment into focus: for wind and photovoltaic power station fluctuation power supply characteristics, wide range voltage regulator transformer R & D accelerated, voltage regulation range extended to ± 20%, to help renewable energy grid consumption.

Fourth, regional co-development release new kinetic energy

Central and western regions relying on the construction of ultra-high voltage power grid, promote the development of transformer industry clusters. For example, Henan Dietrich Electric and other enterprises through the ‘machine + accessories’ industry chain linkage mode, to achieve the box-type substation delivery cycle shortened by 15%, the cost decreased by 10%, the product has covered the ‘Belt and Road’ along more than 20 countries! The products have covered more than 20 countries along the ‘Belt and Road’.

Industry Outlook

In 2025, the transformer industry will be deeply integrated into the construction of new power systems, the annual market size is expected to grow 12% year-on-year, of which intelligent operation and maintenance services, recycling and remanufacturing and other segments of the growth rate will exceed the industry average. Policy guidance and technological innovation under the double drive, ‘efficient power supply + circular economy’ industrial ecology is accelerating the formation of the
