The rated short-time currents given refer to the steel parts and apply for 35°C initial temperature and 400°C final temperature.
Also applicable for steel wires 50 mm².
1. safe support of the conductor under normal operating conditions.
Proper dimensions, specific designs and suitable materials for the individual parts of the suspension clamp assure that the forces resulting from the conductor own mass plus normal or increased additional loads are held with a safety factor of 2.5.
2. securing of the conductor against displacement in the cable direction (not applicable for release and controlled slip clamps)
A sufficiently high clamping force between the conductor and the suspension clamp prevents the conductor from slipping in the direction of the cable in the event of differential pulls.
3. absorption and transmission of aeolian conductor vibrations within the spans via pendulum-type suspension clamp designs with a
- low mass moment of inertia of the oscillating clamp parts,
- low friction in the pivot points,
- Separation of the points of largest alternating bending stress from those of largest transverse pressure,
- conductor support that assures as little as possible bending of the conductor,
- helical armoring between the conductor and the clamps,
- double straps for attachment to the insulator chain or to the ground wire support point
Thus for each type of suspension clamp, conditions are created to not cross that the fatigue strength limits of the individual conductor wires
and to prevent single wire breaks within the clamping area and next to the suspension clamp.
The additional installation of vibration dampers next to the suspension clamps considerably reduces the
the stresses on the suspension clamps caused by conductor vibrations.
1. safe transmission of short-circuit currents from the conductor to the support arrangements
(insulator chain, earth cable support point).
Sufficient dimensioning of the support elements of the suspension clamp and low resistances between the conductor and the suspension clamp ensure that short-circuit currents of the rigidly earthed
grounded networks are transferred into the supporting arrangements.
2. avoidance of partial discharges
By appropriate shaping and suitable inclusion of the suspension clamps into the suspension system of bundled conductors, the corona extinction voltage at the suspension clamps is above the required levels.
This clamp supports and guides the conductor within in the groove of the clamp body.
The maximum permissible conductor outlet angle is 22°.

These suspension clamps are designed for attaching aluminium conductors (AAC), all aluminium alloy
conductors (AAAC), steel reinforced aluminium conductors (ACSR) and steel reinforced aluminium alloy
conductors (AACSR), to suspension chains at locations which are particularly exposed to vibrations.
The helical armour rods protect the suspension point from damage and distribute the acting forces over a larger area/length.
The standard versions of the helicals are right-hand or Z-stranded and the rod ends are faceted. The helicals are variable and individually adaptable to the respective customer requirements.
