前 言
根据国家电网公司国家电网科［2008］928号《关于下达国家电网公司2008年度标准制修订计划（第一批）的通知》，制定本规程。
本标准贯彻“强制性条文、强制性执行”的指导思想。
《输变电工程建设标准强制性条文实施管理规程》是一套系列标准，用于输变电工程建设中强制性条文的执行、检查及记录。
该规程由如下8部分组成： ——第1部分：通则
——第2部分：变电站建筑工程设计 ——第3部分：变电站建筑工程施工 ——第4部分：变电站电气工程设计 ——第5部分：变电站电气工程施工 ——第6部分：输电线路工程设计 ——第7部分：输电线路工程施工 ——第8部分：输变电工程施工安全
本部分是该规程中的第5部分：变电站电气工程施工。对变电站电气工程施工质量强制性条文参建各责任主体单位的执行、检查及记录做了统一规定，尽可能地避免在执行中发生偏差、遗漏和违反强制性条文的情况，有利于变电站电气工程施工水平及工程实体质量的提高。
本规程由国家电网公司基建部提出。 本规程由国家电网公司科技部归口。 本规程由国家电网公司基建部负责解释。
