Description
Technical field
The present invention relates to electric armour clamp mounting technique field, more particularly to a kind of special-shaped anti-skidding preformed armor rods.
Background technology
Because high-tension overhead line bar position is higher, span is larger, when wire is acted on by wind-force, it may occur that vibration, and
Vibration, which occurs, for wire will threaten the safe operation of transmission line of electricity.Therefore, it is the level of vibration of reduction wire, it is ensured that transmission line of electricity
Safe and stable operation, damper is generally installed on wire.In order to ensure damper does not slide installed in specified location,
Stockbridge damper is generally fixed using fixing equipment, in case damper departs from original position and loses vibration-isolating effect, such as not in time
Adjustment, long-play can also fray wire.
At present, widely use preformed armor rods to fix damper, i.e., after damper installation is completed, on shockproof hammer thread clip
Install a whole piece preformed armor rods additional, or provided with several place's salient points above shockproof hammer thread clip, then wound with one circuit with preformed armor rods, using " overall
Be fastened " principle.The structure of preformed armor rods is spiral shape.
But, when fixing damper in the way of winding using existing preformed armor rods, the tail end of preformed armor rods is vertical with wire,
Long-term vibration is easily worn and torn, fray wire；And for realize " being integrally fastened " principle, existing preformed armor rods size compared with
It is long, make installation inconvenient, cost is high.
The content of the invention
