DL/T 5291-2013 (English Version) PDF

Scope: This standard is applicable to 1000kV voltage level overhead transmission lines and substations, using high-pressure oil pumps as power and corresponding stamps for hydraulic construction of ground conductors and supporting hardware. This standard applies to concentrically twisted overhead conductors and ground stipulated in GB/T 1179 "Round Wire Concentrically Stranded Overhead Conductors", YB/T 5004 "Galvanized Steel Stranded Wire", YB/T 124 "Aluminum Clad Steel Stranded Wire" and other standards. Wires, including other wires that meet the requirements of the above standards, are also suitable for expanded wires used in substations (switching stations). This standard is the basis for hydraulic construction and project supervision in 1000kV power transmission and transformation projects.
