Abstract
The invention discloses a novel strain clamp for a large-section wire. The novel strain clamp comprises a steel anchor, a strain aluminum tube and an aluminum liner, wherein an inner crimping tube I is arranged in the strain aluminum tube; the aluminum liner is sleeved with the strain aluminum tube; and the top of the inner crimping tube I is fixedly connected to the steel anchor through a thread. By adopting a layered crimping form, the novel strain clamp has the advantages that the strain force is high, and the wire is uniformly stressed and is not easily damaged.
Description
Technical field
The present invention relates to a kind of new large-section lead strain insulator fixture, belongs to power cable tools technical field.
Background technology
With the fast development of power industry, Great span, large-section lead are using also more and more extensive.But for such
In the case of strain insulator fixture be difficult to meet the requirement of tension force.For this reason, it may be necessary to a kind of new technical scheme is asked solving above-mentioned technology
Topic.
Content of the invention
It is an object of the invention to provide a kind of point three lamination connects, tension is strong, wire uniform force, wire be not easily damaged
Great span and large-section lead strain insulator fixture.
The technical solution used in the present invention is：
A kind of new large-section lead strain insulator fixture, including arranging in steel anchor, strain insulator aluminum pipe and aluminum bushing pipe, the strain insulator aluminum pipe
There is interior aluminium hydraulic pressed connecting pipe I, the aluminum liner sleeve is in strain insulator aluminum pipe, and the top of the interior aluminium hydraulic pressed connecting pipe I is threadably secured and is connected to
On steel anchor.
Further, also include interior aluminium hydraulic pressed connecting pipe II, the top of the interior aluminium hydraulic pressed connecting pipe II is provided with crimping notch, described intrinsic pressure
Adapter II is crimped in interior aluminium hydraulic pressed connecting pipe I.
The present invention is in the form of layering crimping, while adopt two interior aluminium hydraulic pressed connecting pipes, interior aluminium hydraulic pressed connecting pipe I using thread forms and
Steel anchor inner tube connects, and by adjusting the connecting length of screw thread, is brought due to crimping material and technique with solving ectonexine steel core
The inconsistent problem of inside and outside elongation percentage, and then prevent due to discontinuity equalization and cause one layer of extension excessive without complete stress
So as to the generation that situations such as rupturing occurs.
The present invention is additionally provided with interior aluminium hydraulic pressed connecting pipe II in interior aluminium hydraulic pressed connecting pipe I, i.e., by the way of three layers of layering crimping.In crimping
When, first a part of steel core of wire is crimped in interior aluminium hydraulic pressed connecting pipe II, then interior aluminium hydraulic pressed connecting pipe II is crimped in aluminium hydraulic pressed connecting pipe I,
Then again part steel core is crimped in aluminium hydraulic pressed connecting pipe I, and aluminium hydraulic pressed connecting pipe I is crimped on steel anchor by way of screw thread and crimping combine
Interior, finally again remaining steel core is crimped in steel anchor, has been achieved in that steel core divides the purpose that three laminations connect so that steel core stress
Uniformly, strain insulator force value is substantially increased.At the same time, in strain insulator aluminum pipe, aluminum bushing pipe is provided with, in the aluminium lamination of crimping lead wire,
The aluminium lamination of wire is placed in aluminum bushing pipe while crimp, so can effectively reduce compression ratio, it is ensured that it is right to reduce during crimping
The damage of wire aluminium lamination, while the reduction of compression ratio can make wire with steel core while stress playing its sharpest edges respective,
Reach optimal strain insulator effect.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Wherein：1st, steel anchor, 2, aluminium hydraulic pressed connecting pipe II, 3, aluminium hydraulic pressed connecting pipe I, 4, strain insulator aluminum pipe, 5, aluminum bushing pipe, 6, crimping notch.
Specific embodiment
As shown in figure 1, a kind of new large-section lead strain insulator fixture, including steel anchor 1, strain insulator aluminum pipe 4 and aluminum bushing pipe 5,
Interior aluminium hydraulic pressed connecting pipe I 3 being provided with strain insulator aluminum pipe 4, aluminium hydraulic pressed connecting pipe II 2 is crimped with aluminium hydraulic pressed connecting pipe I 3, at the top of interior aluminium hydraulic pressed connecting pipe II 2
The crimping notch 6 being provided with for crimping, aluminum bushing pipe 5 is sheathed in strain insulator aluminum pipe 4, and the top of interior aluminium hydraulic pressed connecting pipe I 3 is solid by screw thread
Surely it is connected on steel anchor 1.
