Advanced Expanded Diameter ACSR Conductor Solution

Expanded diameter steel core aluminum wire   This expanded diameter wire is a special overhead cable specially developed for ultra-high voltage and extra high voltage transmission projects. Based on conventional wire technology standards, it adopts professional expansion technology to optimize structural design. There are two ways to achieve the effect of expanding the diameter of the wire: one is to use the steel core and support layer to create a hollow structure, and the other is to reduce the number of single wires in the aluminum layer and reserve reasonable gaps to increase the equivalent radius of the wire. For high-voltage transmission lines above 220kV, this wire can effectively reduce line reactance, suppress corona discharge, reduce corona losses during transmission, and meet the strict technical requirements of high-voltage transmission. On the premise of meeting the outer diameter standard required for corona protection, reducing the aluminum cross-section significantly r…
