Editor's review

This code is the national standard for the construction and acceptance of overhead power lines of 66 kV and below. It covers the full chain from inspection of raw materials and equipment, surveying, earthwork, foundation works, pole and tower works, stringing works, grounding works, and electrical equipment on poles to project acceptance and handover, and includes four appendices. Its core value lies in specifying quality control points and acceptance criteria item by item during construction, making it easy for engineering and technical personnel to follow on site and reducing rework and disputes caused by misunderstandings. The provisions are technical and prescriptive; readers need to use them together with drawings, construction plans, and current related standards. It is suitable as a standby reference for construction project departments, an inspection basis for supervisors, and a reference for cost and design personnel to understand construction processes. For readers preparing to participate in power engineering acceptance or write construction organization designs, this book provides a systematic process framework and compliance boundaries.

Reading tips

  1. Read the general provisions and terms first to clarify the scope of application and key definitions, then read the corresponding chapters in construction order.
  2. Use the appendices together with the main text and check each item against the checklist before acceptance to avoid missing key control points.
  3. Consult the construction drawings of the project and current mandatory provisions together, and pay attention to the references among standards.
  4. Make quick-reference cards of commonly used clauses for on-site use, facilitating fast reference during construction team briefings and supervisor inspections.

FAQ

What voltage levels of overhead lines does this code apply to? It applies to the construction and acceptance of overhead power lines of 66 kV and below. For line projects at higher voltage levels, other corresponding standards should be consulted; this code cannot be directly applied.
What does the project acceptance and handover section of the code mainly include? This section specifies the organization of acceptance, inspection contents, judgment requirements, and the documents and procedures required for project handover, helping construction and owner units clarify their respective responsibilities and ensuring the project is ready for commissioning.
Can non-power professionals understand this code directly? The code consists mainly of engineering technical provisions, with many terms and construction procedures, so it is difficult for non-professionals to understand. It is recommended to first acquire basic knowledge of overhead line construction processes, then read the provisions alongside them, or use the code together with on-site technical personnel.
What are the practical uses of the four appendices in the book? The appendices usually provide inspection records, inspection methods, or form-type tools to facilitate item-by-item implementation of the main text requirements on site. When using them, attention should be paid to the correspondence between the appendices and the main text provisions, avoiding filling in forms without checking the substantive content.
