Features: This typical construction drawing set is based on the "Typical Design Scheme for 35-110kV Unmanned Substations" and provides construction drawings for three typical schemes: a 35kV substation with two double-winding transformers (each with a capacity of 3.15-6.3 MVA or 8-10 MVA) and a 110kV substation with two three-winding transformers (each with a capacity of 20-31.5 MVA). The typical schemes are designed for unmanned operation and monitored via remote control. The 35kV substation's main transformer capacity of 3.15-6.3 MVA adopts an entirely outdoor layout, while the 8-10 MVA capacity uses a mixed indoor-outdoor layout. The 110kV substation's main transformer capacity of 20-31.5 MVA also uses a mixed indoor-outdoor layout. These various capacity levels can meet the needs of different scales, environments, and economic conditions, such as rural areas, suburban regions, and small towns. Each type includes a design specification, a list of main equipment and materials, and construction and installation drawings, facilitating the selection and reference for similar projects. The key feature of this construction drawing set is its ability to effectively accelerate project startup and shorten the construction cycle. This drawing set is suitable for rural power grid design and construction departments to select or refer to based on project needs, as well as for professionals engaged in engineering management, construction, installation, and operation and maintenance, and for faculty and students of relevant disciplines in universities and colleges.
