Features: Transformers are important equipment for power distribution in the power grid. Currently, China is in a peak period of power construction, and the issue of tight power supply needs urgent resolution. To alleviate the situation of tight power supply, the State Power Corporation has increased the total length of transmission lines, expanded the investment scale of power grid construction, and further increased the transformer capacity, providing broad development space for the transformer industry and promoting the sound development of the transformer manufacturing industry. To support the construction of the national power grid and enable transformer enterprises to obtain accurate and standardized technical information in a timely manner, the "Transformer Standard Collection - Product Volume" is launched. It collects the current national and industry standards for transformer products issued before the end of 2005, divided into two volumes: "Transformer Standard Collection - Product Volume (Volume 1)" collects 50 standards for three product types: transformers, current transformers, and reactors, including 18 national standards and 32 industry standards. "Transformer Standard Collection - Product Volume (Volume 2)" collects 42 standards for three standard types: voltage regulators, components, and general standards, including 7 national standards and 35 industry standards. When using this collection, readers are advised to note the following points: 1. Due to the timeliness of standards, the standards collected in this collection may be revised or reissued. Readers are requested to use the newly effective version when using them. 2. Considering that the publication dates of the standards are not the same, no changes have been made to the inconsistencies in units and quantities, or the inconsistencies in the formats of the various standards. 3. The attributes of the standards collected in this collection are indicated in the table of contents (mandatory or recommended), and the standard year number is expressed in four digits.
