Summary

This code applies to the construction and acceptance of power transformers (hereinafter referred to as transformers), oil-immersed reactors (hereinafter referred to as reactors), voltage transformers, and current transformers (hereinafter referred to as transformers) for AC voltage levels of 3kV to 750kV; the installation of arc suppression coils may be carried out in accordance with the relevant provisions of this code.

Effective date: December 1, 2010.

Editor's review

This code sets out systematic provisions for the construction and acceptance of power transformers, oil-immersed reactors, voltage transformers, and current transformers at AC voltage levels of 3kV to 750kV, and specifies that arc suppression coil installation may be executed by reference, covering the main stages of oil-immersed main equipment installation in substation projects. Its value lies in linking equipment arrival inspection, installation techniques, oil filling and sealing treatment, testing, and acceptance into an executable chain of provisions, reducing quality risks caused by unclear process interfaces. The provisions are engineering-oriented, with accompanying tables and indicators for item-by-item on-site verification. Readers should locate chapters by equipment voltage level and type, focusing on mandatory provisions and acceptance criteria; for key processes such as oil filling and vacuum treatment, it is advisable to cross-reference manufacturer technical documents. This book is suitable as a field reference for substation installation projects and as a basis for preparing construction plans and organizing acceptance documentation.

Who it's for

A good fit for

Substation installation construction personnel who need to complete transformer and transformer installation in accordance with the code
Power engineering supervision and quality inspection personnel who need to conduct acceptance judgments based on the provisions
Power design personnel who need to understand equipment installation requirements for civil works and interfaces
Power engineering students and faculty who need to master national standards for construction and acceptance of oil-immersed equipment

Not a good fit for

Low-voltage distribution and civil electrical readers—this book focuses on 3kV to 750kV oil-immersed equipment
Procurement staff concerned only with equipment selection parameters—this book focuses on construction and acceptance
Beginners without power engineering fundamentals—the provisions are highly specialized and lack explanation of principles

Reading tips

First confirm the project voltage level and equipment type, then locate the corresponding chapters to avoid reading irrelevant sections.
Compile mandatory provisions and acceptance criteria into an on-site checklist and verify item by item as work progresses.
When reading key processes such as oil filling and vacuum treatment, cross-reference the manufacturer's installation and operation manual to understand parameters.
Before acceptance, review documentation completeness in chapter order to ensure test reports correspond one-to-one with code requirements.

FAQ

What voltage levels and equipment scope does the code cover?

According to the source material, it applies to the construction and acceptance of power transformers, oil-immersed reactors, voltage transformers, and current transformers at AC voltage levels of 3kV to 750kV; arc suppression coil installation may be carried out in accordance with the relevant provisions of this code. Before use, confirm whether the equipment type and voltage level fall within scope.

Does arc suppression coil installation fully comply with this code?

The source material states that arc suppression coil installation may be carried out in accordance with the relevant provisions of this code, which constitutes reference application rather than full equivalence. In practice, relevant installation and acceptance provisions should be selected in light of the product characteristics and manufacturer technical requirements of the arc suppression coil, and any ambiguities should be confirmed with the design institute.

What is the most effective way to use this code on site?

It is recommended to use it process by process: equipment arrival inspection, installation, oil filling and sealing treatment, testing, and acceptance each correspond to relevant chapters. Extract mandatory provisions and acceptance criteria into a checklist. This reduces omissions and facilitates verification before concealed works are covered, avoiding rework.
