Dehnklemme

Die Aufhängungsklemme wird hauptsächlich verwendet, um Leiter an Isolatorsträngen zu befestigen oder Blitzableiter an geraden Türmen zu hängen. Darüber hinaus kann sie auch für Transpositionsmasten verwendet werden, um Transpositionsleiter zu unterstützen und für Spannungsmasten oder Winkelpfosten, um die Sprungdrähte zu fixieren.

  • According to its configuration and installation means, the strain clamp can be divided into compression type, bolt type and wedge type. Generally, the compression type includes hydraulic compression type and explosive compression type.

The strain clamp adopts a wedge-shaped structure design. There is no need for a drain clamp, eliminating the problem of heating at the connection of the drainage plate. The installation is more convenient without the need for cutting wires or crimping tools, which can save time and improve efficiency.
