GB/T 30550-2014
ActiveConcentric lay stranded overhead electrical conductors containing one or more gap(s)
含有一个或多个间隙的同心绞架空导线
Application Summary AI generated
This standard specifies the construction, dimensions, and performance requirements for concentric lay stranded overhead electrical conductors that incorporate one or more longitudinal gaps between wire layers. It is applied in the design and manufacturing of high-voltage overhead power transmission lines, particularly for conductors requiring reduced wind load or ice shedding properties, such as those used in long-span or heavy-icing regions. The standard ensures mechanical and electrical consistency for procurement and quality testing in the electrical power industry.
