📝 Foreword / 前言 ai_extracted

This standard is formulated in accordance with the electric power industry standard planning project under the former Ministry of Electric Power's Technical Comprehensive [1996] No. 51 document, and the electric power fitting standards are consolidated and classified by type. This standard DL/T 764.1—2001 replaces SD 25—1982 "Hexagon head bolts with split pin hole on shank". In the revision of SD 25—1982, it is noted that the current national standard GB 5780—2000 adopts a necking transition process between the unthreaded portion and the thread of the bolt, which is not suitable for use in electric power fittings. This standard specifies equal-diameter shank bolts. This standard shall be implemented from February 1, 2002. From the date of implementation, all standards related to this standard submitted for approval shall comply with the provisions of this standard. This standard is under the jurisdiction of the National Technical Committee on Overhead Lines (Electric Power Fittings) Standardization. This standard was drafted by the Electric Power Construction Research Institute of the State Power Corporation. Main drafters of this standard: Dong Ji'e, Xu Naiguan, Xu Shaoxian, Bo Tong, Zhao Junhu, Sun Yuqing. This standard is interpreted by the National Technical Committee on Overhead Lines (Electric Power Fittings) Standardization. People's Republic of China Electric Power Industry Standard Electric power fitting fasteners — Hexagon head bolts with split pin hole on shank DL/T 764.1—2001 Replaces SD 25—1982

本标准根据原电力部技综［1996］51号文电力行业标准计划项目进行制订，并将电力金具标准按种类进行归并分类。本标准DL/T 764.1—2001代替SD 25—1982《六角头带销孔螺栓》。对SD25—1982的修订，注意到现行国标GB 5780—2000中螺栓的无螺纹段与螺纹间的工艺为缩颈过渡，不适用于电力金具使用，本标准为等颈螺栓。本标准自2002年02月01日起实施，从实施之日起，所有报批的与本标准有关的标准，均应符合本标准的规定。本标准由全国架空线路(电力金具)标准化技术委员会归口。本标准由国家电力公司电力建设研究所负责起草。本标准主要起草人：董吉谔徐乃管徐绍贤薄通赵君虎孙玉庆本标准由全国架空线路(电力金具)标准化技术委员会负责解释。中华人民共和国电力行业标准电力金具专用紧固件六角头带销孔螺栓 DL／T 764.1—2001 代替SD 25—1982 Electric power fitting fasteners Hexagon head bolts with split pin hole on shank
