Beijing, [Date] – A new generation of high-performance cylindrical transformers, hailed for their superior energy efficiency and operational stability, has recently been widely deployed in key new energy power grid projects across northern and southern China, marking a significant step forward in the country’s efforts to build a low-carbon power system. Developed by a leading domestic power equipment manufacturer in collaboration with academic institutions, these transformers are set to reshape the landscape of power transmission and distribution with their innovative design and reliable performance.
Unlike traditional laminated transformers, the newly launched cylindrical transformers adopt an integrated winding structure and advanced insulating materials, achieving outstanding performance indicators. Official data shows that the no-load loss of these transformers is reduced by more than 35% compared to national standard requirements, the noise level is controlled below 55 decibels, and the short-circuit resistance stability under extreme operating conditions is increased by 40%, effectively solving the problems of voltage fluctuations and operational safety in large-scale new energy grid connection scenarios.
"The widespread application of cylindrical transformers will bring disruptive changes to the new energy industry," said an industry expert in the field of power grid technology. "With the rapid expansion of wind power and photovoltaic installed capacity, the demand for high-efficiency, low-noise, and stable transformers has surged. Such cylindrical transformers not only improve the overall efficiency of power transmission but also reduce the environmental impact of power facilities, which is highly consistent with the national 'dual carbon' goals."
The first batch of such cylindrical transformers has been put into operation at a 1000MW photovoltaic power station base in Qinghai and an 800MW wind power project in Inner Mongolia. Preliminary operation data shows that the equipment has significantly reduced the energy consumption and operation and maintenance costs of the projects. A project manager pointed out: "Since the commissioning of the cylindrical transformers, the stability of the power grid during peak energy generation periods has been greatly improved, and the annual power saving of a single unit is expected to reach 1.2 million kWh."
Looking ahead, the manufacturer plans to further advance the research and development of cylindrical transformers, targeting higher voltage levels and intelligent upgrading. It will focus on promoting the integrated application of online monitoring technologies such as partial discharge detection and dissolved gas analysis in oil to achieve real-time fault early warning and predictive maintenance. Industry insiders predict that driven by the continuous expansion of new energy projects and the upgrading and transformation of urban power grids, the market demand for cylindrical transformers will grow at an annual rate of 8%-10% in the next five years.
