Unlike underground cable installation, pulling in conductors can generate significantly higher tensile forces, which the overhead line grips must withstand.

For this reason, heavier strands and a three-strand mesh are required. However, to ensure that the overhead line grips remain flexible, the mesh is stepped in 3 sections, corresponding to the occurring tensile load distribution:

Section with single-strand mesh – for absorbing low loads and establishing the friction lock

Section with two-strand mesh – for absorbing higher loads and further establishing the friction lock

Section with three-strand mesh – for absorbing the full load and fully establishing the friction lock

The resulting self-clamping effect gives the pulling grip high resistance to slipping on the conductor.

With pressed rope eyelet for conventional cable pulling; however, due to their rigid ferrules, these pulling grips are not suitable for pulling over bullwheels, capstan heads or Figure-eight brakes with diameters of less than 1000 mm. There is a risk that individual strands of the outer layer will be levered off directly at the ferrule.

Samples of the pulling grips are submitted to an independent rope testing institute for breaking tests. Upon request, when supplying overhead line grips, we provide our customers with instructions for use (based on practical experience) and a table listing all technical data.
