Bolted clamps

Bolted clamps were developed to anchor self supporting LV-ABC lines. Some of them can be used as universal solutions of anchoring and suspension service cables in low voltage insulated overhead lines.

These LV ABC fittings are applicable for self-supporting low-voltage cable with 4 or 2 insulated overhead conductors. Minimal breaking load of bolted clamp is higher than wedge type aluminum or plastic clamps, because they are bigger and made of galvanized metal parts, weather and UV resistant fiberglass reinforced plastic, stainless or galvanized hardware.

The bolted clamps, which produced by Jera line fittings can be divided to:

* Anchoring clamps for self supporting LV-ABC lines
* Anchor or suspension clamps for service cables
* Anchor clamps for service cables
Different mount system allow installations with the LV ABC hooks or LV brackets. Anchoring clamps and LV ABC suspension hooks are available either separately or together as assembly. All the assemblies passed the tensile tests, operation experience with temperatures ranging from –60 °C up to +60 °C test, temperature cycling test, aging test, corrosion resistance test etc.

This low voltage accessories conform to the standard CENELEC EN 50483-2.


Insert conductors between the wedges. Self opening feature is realized by springs that keep the clamp in open position during the installation. Pull conductors in the strain clamp and upstream them to the pole, to tensile the aerial bundled cable. Then, properly tighten the nut until needed torque will be reached.
