On the basis of such scheme and as the preferred scheme of such scheme：The pre-hinged strain clamp is in itself and the heart Shape ring connection end to this section between main traverse line is provided with packing, and the packing is completely wrapped in preformed resistance to bracing cable Folder is internal.

On the basis of such scheme and as the preferred scheme of such scheme：The packing is isometrical with main traverse line Steel strand wires.

On the basis of such scheme and as the preferred scheme of such scheme：The shield lines are wrapped on main traverse line, The pre-hinged strain clamp is wrapped on shield lines.

On the basis of such scheme and as the preferred scheme of such scheme：The shield lines are spiral preformed Silk.

On the basis of such scheme and as the preferred scheme of such scheme：What the shield lines were wound on main traverse line Length is not shorter than the length that pre-hinged strain clamp is wound on main traverse line.

On the basis of such scheme and as the preferred scheme of such scheme：It is twisted among the preformed shunt bar, Its both ends is preformed free end.

The utility model is prominent and beneficial compared with prior art to be had the technical effect that：In the base of original compression strain clamp Increase a set of pre-hinged strain clamp on plinth, it is still tensed wire when compressing strain clamp and breaking down and lead Galvanization, pre-hinged strain clamp one end are connected by thimble with steel tower gold utensil, and the other end is wrapped on main traverse line, and it winds Shield lines are provided between portion, so do that its connector is few, the workload of installer is small, and cost reduces, in addition among connect Part, which is reduced, also can improve the reliability of connection, and protecting the setting of lines can be such that stress is uniformly dispersed on main traverse line.

Embodiment

To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with the accompanying drawing in embodiment, to reality The technical scheme applied in example is clearly and completely described, it is clear that described embodiment is only that the application part is implemented Example, rather than whole embodiments.Based on the embodiment provided, those of ordinary skill in the art are not before creative work is made The every other embodiment obtained is put, belongs to the scope of the application protection.

In the description of the present application, it is to be understood that the orientation or position relationship of the instruction such as term " on ", " under " are base In orientation shown in the drawings or position relationship, it is for only for ease of description the application and simplifies description, rather than indicate or imply Signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this The limitation of application.

In the description of the present application, term " first ", " second " etc. be only used for describe purpose, and it is not intended that instruction or Imply relative importance or the implicit quantity for indicating indicated technical characteristic.

It should be noted that term " electrolyte ", " gelatinizing agent " are the current material of this area and conventional use of material Material, and above-mentioned technical characteristic is also inventive point not of the invention, therefore, is not made for the composition of " electrolyte ", " gelatinizing agent " Repeat.

One kind preformed three across strengthen strain clamp, comprising thimble 2, compression strain clamp 5, pre-hinged strain clamp 3, Preformed shunt bar 6, one end of the thimble 2 are connected with the gold utensil 1 of steel tower side, the middle part of the pre-hinged strain clamp 3 with The other end connection of thimble 2, another both ends are wrapped on main traverse line 7, make its when compressing strain clamp and breaking down still Wire and conducting electric current can be tensed.

The groove at the middle part for accommodating pre-hinged strain clamp 3 is provided with thimble 2, hole is provided with the plate on the groove both sides, Thimble 2 is fixed on the gold utensil 1 of steel tower side by the hole by pin joint or bolt connection.

Pre-hinged strain clamp 3 is provided with packing 8 in itself and the connection end of thimble 2 to this section between main traverse line 7, The packing 8 is completely wrapped in inside pre-hinged strain clamp 3.To improve bonding strength, preformed resistance to bracing cable is prevented Its helical compression when by action of pulling stress of folder 3 causes its grip to wire to reduce than changing.
