Full title and description

Overhead lines with nominal voltages exceeding 1 kV — Methods and equipment for the installation of conductors — Part 2: Cable grips (Freileitungen mit Nennspannungen über 1 kV - Verfahren und Ausrüstung zum Verlegen von Leitern - Teil 2: Ziehstrümpfe aus Stahl). This part specifies requirements, design and test guidance for steel cable grips used when stringing conductors on overhead power lines.

Abstract

DIN 48207-2:2005-06 defines the purpose, constructional characteristics and minimum performance requirements for steel braided cable grips (Ziehstrümpfe) intended for use when installing conductors on overhead lines above 1 kV. The document covers mechanical strength, recommended handling and testing principles to ensure safe conductor pulling and transfer of tensile loads during installation.

Scope

The standard applies to steel braided cable grips used for the installation (stringing and pulling-in) of conductors on overhead power lines with nominal voltages exceeding 1 kV. It addresses mechanical design, dimensions and ranges (working diameters), required tensile performance and test criteria so grips will reliably transfer pulling loads without damaging conductors. The document is intended to be used together with the relevant overhead-line standards (for example the EN/DIN EN series for overhead line construction).

Key topics and requirements

• Definition and classification of steel cable grips for overhead-line conductor installation.
• Design and construction requirements (braid geometry, eyes/loops, ferrules and material considerations for steel grips).
• Nominal/working diameter ranges and matching to conductor sizes.
• Mechanical performance requirements: tensile/pulling force capability and minimum breaking strength tests (requirements for proof or type testing and acceptance criteria).
• Marking, documentation and handling guidance to ensure safe use during stringing operations.
• Testing methods and inspection requirements to verify conformity before field use.

Typical use and users

Primary users are transmission and distribution utilities, overhead-line construction and stringing contractors, manufacturers and suppliers of cable grips and pulling equipment, testing laboratories and safety/inspection personnel involved in overhead-line installation projects. The standard is used to specify procurement requirements, verify product conformity and guide safe installation practice.

Related standards

Commonly referenced documents include standards for overhead line design and installation (e.g. DIN EN 50341 series / VDE: overhead-line design and construction), related parts of the DIN 48207 series (other parts covering connectors and handling equipment) and product-specific standards for conductors and fittings. The 2024 revision of Part 2 aligns references and test language with the current EN/VDE framework.
