With its excellent low temperature resistance, Kechang Electric's extremely cold transformers achieve zero-fault continuous operation in extreme environments from -30℃ to -40℃, and successfully complete the task of power transmission and new energy grid-connected guarantee, which has been highly recognized and praised by users of the Northern Power Grid and wind power projects.
Extremely cold weather puts forward strict requirements for the operating reliability of transformers. The low-temperature environment can easily cause the viscosity of the insulating oil to increase, the heat dissipation to deteriorate, the seals to harden and age, leakage occurs, the insulating materials to become brittle and crack, and even cause problems such as equipment protection malfunction and failure to start normally. It has become an important hidden danger in the winter power supply in the north.Kechang Electric is deeply engaged in the field of power equipment. In view of the extreme climate characteristics of the north, it has specially developed extremely cold transformers, and upgraded them in all directions from material selection, structural design to performance optimization, so as to accurately crack the industry pain points of equipment operation in extremely cold environments.

The Kechang extremely cold transformers that have been put into use in power grids and wind power projects in many places in the north have been tested in actual combat in extreme weather and have shown three core advantages.
1. Super low temperature resistance, using high-toughness modified insulation materials and special low-temperature-resistant seals, with intelligent preheating start-up module, even in extremely cold and blizzard weather of -40℃, the insulation performance can be maintained stable, the seal is intact, and freeze-damaged failures can be avoided;
2. High reliability, optimize the winding structure and cooling system design, effectively solve the problems of slow heat dissipation in low-temperature environments, loose thermal expansion and contraction of components, and achieve continuous and stable operation without any downtime alarms;
3. The maintenance-free characteristics, through refined process upgrades and intelligent monitoring design, greatly reduce the operation and maintenance costs in extreme environments. Reduce the pressure of manual inspection, and adapt to complex operation and maintenance scenarios such as remote areas in the north and alpine wind power projects.

At present, Kechang extremely cold transformers have been widely used in power grid upgrades and wind power project supporting scenarios in Northeast China, Inner Mongolia, Northern Hebei and other northern regions, providing a solid guarantee for the stable supply of local electricity and the grid-connected consumption of new energy sources. In the past, some equipment had frequent start-up difficulties, failures and shutdowns in extremely cold weather. After Kechang's extremely cold transformers were put into use, they operated with zero failures throughout the process, which not only guaranteed the progress of the project, but also gave us more confidence in the winter power supply. Rest assured. The person in charge of operation and maintenance of a power grid project in the north said that the low temperature resistance and high reliability performance of Kechang transformers perfectly meet the operating needs of equipment in extreme climates in the north, and will continue to deepen cooperation with Kechang Electric in the future.
As an enterprise focusing on power equipment research and development, production and service, Kechang Electric has always been market demand-oriented, focusing on equipment performance improvement in extreme environments, and relying on technological innovation to solve industry problems. The stable performance of the extremely cold transformer in the -40℃ environment not only demonstrates Kechang Electric's deep technical research and development strength and strict quality control level, but also further verifies the adaptability of the product under extreme operating conditions.
In the future, Kechang Electric will continue to deepen the construction of new power systems, continuously optimize the research and development and production of extremely cold, energy-saving, and intelligent power equipment, continuously improve the extreme environmental adaptability and core competitiveness of products, and use more reliable products and better services to help the northern region upgrade the power grid and the high-quality development of the new energy industry, and inject Kechang's strength into the realization of the national "dual-carbon" goal and energy security.
