The important component part of system safety operation.Under normal circumstances, strain clamp port is level or the ramp-like operation that dips down, but
In the overhead transmission line of some extreme terrains, adjacent two base shaft towers there is bigger difference in height and span is less so that highly
The strain clamp of relatively low side shaft tower is presented and is pulled out form operation;Additionally, for normal condition port be within level or 10 ° downwards
The strain clamp tilted, wire tension varies with temperature with sag in cold weather, also can make strain clamp to a certain extent
Present and pull out form.Once meet with sleety weather, rainwater or snow water will carry over wire pour in down a chimney inflow strain clamp in.Strain clamp exists
Typically use welding procedure during production, do not reserve leaking hole, and steel anchor crimps well with aluminum pipe afterbody when assembling crimping so that
Rainwater or snow water are retained and cannot be escaped to aluminum pipe crimpless district, when running into freezing weather especially, after the water in aluminum pipe freezes
The squeezing action produced will have a strong impact on the service life of strain clamp, the safe and stable operation of harm transmission line of electricity.The lowest
Under the conditions of temperature, wire tension increases, the conjunction that the extruding force now produced at wire tension and internal water icing volumetric expansion produces
Under power effect, strain clamp aluminum pipe is susceptible to deformation, even ruptures time serious.
In prior art, " the resistance to bracing cable of carbon fiber photoelectric composite lead wire Anti-freezing of Patent No. 201320159474.1
Folder ", this patent is directed under normal operation, and water enters the situation within aluminum pipe at strain clamp afterbody steel anchor, and
Cannot avoid on wire clamp, pulling out rear water and carry over the situation of wire inflow wire clamp.
In sum, prior art there is problems in that, existing strain clamp, in the case of frost, is susceptible to
Deformation or fracture.
