Picture the last pole of a new overhead route. The cable comes in from the span, and the tension of the whole line now hangs on one small wedge assembly at the pole. An anchoring clamp, often called a wedge type tension clamp, grips the cable, holds that tension, and passes the load into the pole bracket through its bail. This anchoring clamp installation guide walks the complete sequence for LV ABC bundles and insulated conductors, from pre-check to final inspection.<\/p>\n
Since 2003, RaxPower has manufactured pole line hardware on hot-forging lines. The field notes behind this guide come straight from the installation questions that utility crews and line contractors raise with our engineering desk. The sequence below reflects how wedge clamps actually behave on the pole, not just how they look in a catalogue drawing.<\/p>\n
\nThe short version:<\/strong><\/p>\n
\n
An anchoring clamp installation starts at the pole: bracket first, then clamp, then cable.<\/li>\n
The wedge grips tighter as line tension rises, so no torque value applies.<\/li>\n
Match the clamp to the cable’s insulation diameter and inspect the wedge before loading.<\/li>\n
Finish with a service loop and a hand-check before the crew leaves the pole.<\/li>\n<\/ul>\n<\/div>\n
How an Anchoring Clamp Holds an Overhead Line<\/h2>\n
Insulation clean and undamaged at the grip length<\/td>\n
Abraded or burned insulation inside the wedge path<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
In our experience, most clamps that slip in service were damaged before loading, not worn out on the line. A wedge that has rolled across the switchboard floor can look serviceable and still fail to bite, so treat dropped wedges as expendable and swap them without argument.<\/p>\n\nClamp family covering different cable diameter ranges<\/figcaption><\/figure>\n
Also confirm the design intent at this point. Single-core clamps grip one insulated core each, so a four-core bundle needs a set, while bundle clamps close around the whole cable in one body. Mixing the two up mid-installation costs a second trip up the pole.<\/p>\n
