Tension fittings

Depending on the design and a contact method, the tension clamps are classified into the following types:

• wedge clamps with a one-sided wedge;
• bolted clamps ;
• self-wedging clamps;
• compression tension clamps;
• transposition tension clamps;

The tension fittings provide the self-supporting fixation of a conductor or ground wire to a tension string of the angle tension tower and take up the tension load under normal operating conditions, wind and icing load.

Wedge clamps with a one-sided wedge, intended for fixing of aluminum and copper conductors of a cross-section 16 to 95 mm ², and with a double sided wedge (thimble), intended for fixing of steel-aluminum conductors of a cross-section 10 to 50 mm ² or steel wires of a diameter 6.6 to 15.5 mm;

Bolted clamps used for fixing of aluminum, steel-aluminum and copper conductors of a cross-section 70 to 300 mm ²;

Self-wedging clamps for fixing of aluminum and steel-aluminum conductors of a cross-section 70 to 150 mm ² without any special treatment, only through self-locking by a turn wedge;

Compression tension clamps for fixing of steel-aluminum conductors of a cross-section 185 mm ² and above to a tension set, and also for stringing the steel-aluminum conductors of high durability, steel ropes and hollow aluminum conductors;

Transposition tension clamps for transposition of steel-aluminum conductors on a tower;
