Foreword
This code is revised from the original national standard “Code for Design of 10kV & under Electric Substation" (GB 50053-94) jointly by China Electric Design & Research Institute, Co., Ltd. and other organizations concerned according to the requirements of the former Ministry of Construction-"Notice on Printing Development and Revision Plan of National Engineering Construction Standards in 2001~2002" (JIANBIAO [2002] No. 85). The drafting group of this code formulated and finalized this code by conducting extensive investigations, carnestly summarizing the practical experiences, making reference to the related international standards and foreign advanced standards as well as extensively soliciting opinions. This code prises 6 chapters with the main contents as follows: general provisions, selection of substation location, electrical part, layout of switchgear and transformer, shunt capacitor and requirements on relevant specialties. There have been some significant changes in this code in the following technical aspects: 1 Code name was changed into “Code for Design of 20kV and Below Substation° from "Code for Design of 10kV & under Electric Substation"; pe oo usponpd semp s oos uogejsqns spun pue Ao1, wong _uoeysqns 3Technical requirements for aspects of design of 20kV substation were added; 4 Design requirements and fire protection requirements for substations in high-rise civil buildings were added; 5 Contents of "prefabricated substation" were added; 6Provision for new type operational power supply of substation was added; 7 Provision for engineering design of shunt capacitor was supplemented; 8Provisions for design of substation over aspects such as fire protection and building were supplemented, improved and modified; 9 Other provisions of the former code were supplemented, improved and modified. Provisions printed in bold type are pulsory ones and must be enforced strictly. Ministry of Housing and Urban-Rural Development is in charge of the administration of this standard and the explanation of the pulsory provisions; China Machinery Industry Federation is responsible for daily management, and China Electric Design & Research Institute, Co., Ltd. is responsible for the explanation of specific technical contents. During the process of implementing this code, if contents that need modification or supplementation are found, please send opinions and suggestions to China Electric Design & Research Institute, Co., Ltd. (addres: China Electrical Engineering Building, No. 9, Shouti South Road, Haidian District, 100048, Beijing). drafting staffs and chief examiners of this code: Chief development organization: China Electric Design & Research Institute, Co., Ltd.
