    What Is Screened Cable? A Brief Introduction to Screened Cables

    Screened cables are electrical cables with an additional screen layer. In this way, the cables are made resistant to external electromagnetic interference. The screen in the cable structure is also a measure to improve the electric field distribution. The cable conductor usually consists of several stranded wires. This usually creates an air ga...

    Copper, Aluminum and Aluminum Alloy Cables

    The history of human use of copper can be traced back to 10000 years ago. An 8700-year-old cultural relic was unearthed in the northern part of Iraq, the bronze ear cup. China had bronze wares in the Xia Yu period more than 4000 years ago. The application of copper as a conductor has gone through more than 200 years of history with the discovery and application of...

  • Overhead Conductor Gallop Phenomenon

    Overhead Conductor Gallop Phenomenon

    Overhead conductor gallop is a unique mechanical movement expressed in the form of large low-frequency oscillations of the conductor. It is produced under certain environmental and meteorological conditions. This phenomenon is due to the uneven ice coverage of the transmission line conductors (conductores de líneas de transmisión). A low frequen...
