ShunNa Shares' over 340,000 lots hit the daily limit! Over 7 billion yuan in main force funds pour into this sector

The power grid equipment sector advanced early in the trading session.

On March 6, the A-share power grid equipment sector continued to strengthen, with a net main capital inflow of 7.632 billion yuan in the morning, ranking first among the secondary industries in Shenwan. Six stocks in the sector, including Shun Na Shares (000533), Samsung Medical, Radio & Television Electric, and Jiangsu Huachen, hit the daily limit. Among them, Shun Na Shares had an order volume exceeding 340,000 lots in the morning.

Regarding news, the 2026 government work report emphasized building a new type of power system and accelerating smart grid construction. In developing new forms of smart economy, new infrastructure projects such as ultra-large-scale intelligent computing clusters and computing-electrical collaboration are being implemented. These policies are expected to continue creating development opportunities for the power grid equipment industry.

Notably, computing-electrical collaboration was included in the government work report for the first time in 2026. Data centers are stable, high-energy-consuming loads with rigid demand for low-cost, zero-carbon green electricity. In recent years, with the rapid growth of AI computing power, data center electricity demand has exploded. According to a report by Schneider Electric, by 2030, under high electricity consumption scenarios, China’s data centers may exceed 700 billion kWh, accounting for 5.3% of the national total electricity consumption. Computing-electrical collaboration requires the power grid to have strong intelligent dispatching capabilities to dynamically match computing load with power supply. Smart grids, AI dispatch platforms, and virtual power plants are expected to benefit significantly.

Industry Policies Favoring Growth

The policy environment for the power grid equipment industry continues to send positive signals. In September 2025, the “Work Plan for Stabilizing Growth in the Power Equipment Industry (2025–2026)” was released, proposing to promote smart microgrid construction and energy storage applications on the power source and grid sides. By the end of 2025, the “Guiding Opinions on Promoting High-Quality Power Grid Development” was issued, emphasizing strengthened multi-level planning and operation coordination of main trunk grids, distribution networks, and smart microgrids.

At the local level, provinces and cities such as Beijing, Jiangsu, and Fujian actively implement national directives, releasing specific plans and support measures to promote the development of smart grids, virtual power plants, and computing-electrical collaboration. Additionally, during the 14th Five-Year Plan, State Grid Corporation of China’s fixed asset investment is expected to reach 4 trillion yuan, with efforts to enhance resource allocation, increase grid investments, and accelerate the commissioning of 15 ultra-high-voltage direct current projects included in planning. Cross-provincial transmission capacity is targeted to increase by 35%.

According to a research report by Guojin Securities, as the proportion of new energy installed capacity continues to rise and new high-energy-consuming loads like AIDC emerge, upgrading grid infrastructure faces urgent demand. The current planning by State Grid not only targets large-scale infrastructure investment but also emphasizes system flexibility and intelligence. The overall focus of grid investment will shift substantially toward a “inter-regional mutual aid (main grid) + flexible capacity (distribution grid) + flexible dispatching (intelligent systems)” structural upgrade.

15 Stocks Under Intensive Institutional Research

According to Securities Times Data Treasure, there are 137 listed companies in the power grid equipment industry in the A-share market. Some stocks have received significant institutional attention since the beginning of the year, with 15 stocks being researched by more than 10 institutions. Huaming Equipment, Huatong Cables, Siyuan Electric, and AnKao Smart Electric have been researched by over 40 institutions each. Among sub-sectors, the ultra-high-voltage concept is the most favored by institutions, with Huaming Equipment, Siyuan Electric, and AnKao Smart Electric all associated with ultra-high-voltage concepts.

During investor research activities, Huaming Equipment stated that by 2025, the company’s DC ultra-high-voltage line on-load converter station has achieved mass operation and reached benchmark technical standards. Last year, the company’s market share in 500kV and 750kV ultra-high-voltage segments also increased. Although the ultra-high-voltage sector is a new start for the company, it is confident that it can gradually increase its market share as it has in other lower voltage levels.

From a capital perspective, power grid equipment stocks have performed well recently and attracted leveraged funds. Since the beginning of this month, 26 stocks have seen net financing inflows exceeding 10 million yuan, with Changcheng Technology, XinFengGuang, and China Western Electric leading, with net inflows of 94.2463 million yuan, 84.2464 million yuan, and 73.8009 million yuan, respectively.
