The main transformer, as the core equipment of a substation, relies on a professional main transformer structure for its safe and stable operation. Made from high-strength steel, the main transformer structure primarily serves the functions of securing, supporting the transformer, and installing surrounding cables, forming the "core skeleton" for the safe operation of the substation.

Its core advantages include: 1. Strong load-bearing capacity, supported by precise mechanical calculations, enabling stable support for heavy main transformer equipment weighing hundreds of tons; 2. High structural stability, with a frame-type design, offering excellent wind and seismic resistance; 3. Easy maintenance, with ample maintenance passages and operational space, facilitating routine maintenance and fault repair for the main transformer equipment. The quality and design level of the main transformer structure directly impact the power supply capacity and operational safety of the substation, making it a key facility for ensuring the stability of the power grid's core sections.
