Product Details

Protection fittings: are used to restrain vibration of conductor and ground wire of overhead transmission lines, or to grade and to shield the insulator string of 330kv and above.

It includes:

1.preformed armour rod

2.stockbridge vibration dampers

3.spacers, spacer dampe

4.grading and shielding rings

5.counter weight

6.arcing horn

7.guy grip deadend

8.side tie and distribute tie

9.A short time after it was detected that there are vibrations on conductors, energy-absorbing dampers were installed. Up to now, this method is the most effective solution.

Stockbridge dampers with forged clamps for aluminium-, al-alloy-, ACSR-, AACSR- and alumoweld conductors. Weights are cast onto the messenger wire.

Spiral dampers for light conductors, earth wires and optical cables.

The function of this type is to disturb the vibration and this prevents the building up of a standing wave.
