Polaris smart grid online news: on November 15, we learned from the website of the national standardization administration committee that the national standard “technical specification of metal tools for dc transmission lines under the guidance of the Chinese academy of electrical sciences” was approved and published. The standard number is GB/T 31235-2014 and will be implemented on April 1, 2015. The national standard “technical specification of 1000kV substation fittings” has been approved and published. The standard number is GB/T 31239-2014 and will be implemented on April 1, 2015.
National standard “technical specification for + 800 kv dc transmission line hardware in uhv dc transmission line hardware engineering research, design, manufacture, test results, on the basis of the combination of ultrahigh pressure line hardware ripe experience, and rules for + 800 kv dc for overhead transmission line conductor supporting the general technical requirements, design and manufacture of hardware, connecting and fastening, inspection and test, the logo and packing and so on, in such aspects as structure rationality and safety reliability higher requirements are put forward. The standard is an important part of uhv dc standard system, the implementation of the standards will further improve the uhv technical standard system, is advantageous to the specification of uhv dc transmission line hardware design, manufacturing, purchasing and inspection work, ensure quality of hardware products, on subsequent uhv dc engineering construction has the vital significance.
National standard “technical specification for 1000 kv substation hardware in uhv substation communication experiment and demonstration engineering hardware, on the basis of research results and engineering application experience, provides for uhv substation design and manufacture of hardware, connecting and fastening, inspection and test, the packing and shipping requirements, such as some technical indicators and the request is higher than the current hardware standards or specifications. The implementation of this standard will further improve the uhv ac transmission standard system, which is conducive to standardizing the design, manufacturing, procurement and inspection of 1000kV substation fittings, and guaranteeing the quality of the fittings, which is of great significance for the construction of the following uhv ac projects.
