Abstract

The utility model discloses an aluminum armour tape, which is composed of an inner aluminum strip layer and outer rough surface layers. The aluminum armour tape is divided into two forms as follows: the first form, under the condition that the thickness of 1mm of the original inner aluminum strip layer is not changed, one layer of particles is respectively stuck on the upper surface and the lower surface of the inner aluminum strip layer to form the outer rough surface layers, and the thickness of the stuck particles is not larger than 0.5mm; and the second form, the thickness of the inner aluminum strip layer is appropriately increased to 1.5mm from 1mm, the upper surface and the lower surface of the thickened inner aluminum strip layer are respectively polished by 0.25mm to form the uneven outer rough surface layers. When the aluminum armour tape is twined on a conducting wire, the aluminum armour tape is twined along the inherent twining direction of the outer layer of aluminum conducting wire, the twining length is advisable to appropriately widening the width of a hard ware fitting, and the tail end of the aluminum armour tape is folded into a contact surface of the hard ware fitting with the aluminum conducting wire. On the basis that the original performances of the aluminum armour tape is kept, the fiction force between the aluminum conducting wire and the iron hard ware fitting is increased, the shifting or loosening probability of the iron hard ware fitting is reduced, the line repair times are reduced, the daily maintenance cost of lines is reduced, and the safe operation of the lines is ensured.

Description

A kind of aluminium armor tape

Technical field

The utility model relates to the aluminium armor tape on a kind of transmission line wire, particularly a kind of rough surface aluminium armor tape.

Background technology

In power construction, especially in the transmission line construction, aluminium armor tape is widely used.Aluminium armor tape is loaded between lead and the gold utensil, prevents that lead from because of long-time vibration damages, shielding to lead.Stockbridge damper place like transmission line of electricity just should use aluminium armor tape in strict accordance with rules, but in real work, after circuit moves a period of time; Stockbridge damper can be shifted; No longer be between original design-calculated vibration crest and the trough, thereby have influence on the performance of this gold utensil, do not have antihunt action.Cause the reason of this kind phenomenon, one is because the installation of stockbridge damper is not in place, a prior problem that reason is an aluminium armor tape itself; Because aluminium armor tape is the design of light face, the contact surface friction force of lead and aluminium armor tape, aluminium armor tape and gold utensil is less, even if fastening putting in place during installation; Operation a period of time; Because of expanding with heat and contract with cold of lead and gold utensil, the friction force of contact surface is changed, at friction force during less and circuit aeolian vibration; The gold utensil that is loaded on the lead will squint inevitably, has influence on the safe operation of circuit.

Summary of the invention

The utility model is intended to solve the problem that above-mentioned prior art exists, and the conventional aluminum band is improved, and increases the friction force of aluminium armor tape and lead, gold utensil contact surface, gets loose after avoiding lead and gold utensil fastening and is shifted the smooth operation level of raising circuit.

The technical scheme that the utility model adopts is following:

This aluminium armor tape has following two kinds of forms:

Aluminium armor tape constitutes by interior aluminium strip layer and outer coarse surface layer.

First kind of form be do not change original under the situation of aluminium strip layer thickness, each sticking one deck granular substance that is coated with forms outer coarse surface layer on the upper and lower surfaces of interior aluminium strip layer, the sticking thickness that is coated with granular substance is not more than 0.5mm.

Aluminium strip layer thickness preferred value is 1mm in said.

In said on the upper and lower surfaces of aluminium strip layer to glue the granular substance that is coated be carborundum.

Second kind of form is the thickness of aluminium strip layer in suitably increasing, and at the upper and lower surface that increases the thick aluminium material 0.25mm thickness of respectively polishing, forms outer coarse surface layer.

Should interior aluminium strip layer thickness preferred value be 1.5mm.

Said second kind of form increases the upper and lower surface of thick aluminium material through mechanical grinding at interior aluminium strip layer, the coarse surface layer of being polished is uneven.

When above-mentioned two kinds of form aluminium armor tapes twine on lead, all should twine along the intrinsic coiling direction of outer aluminium conductor, coiling length suitably relaxes with adorned gold utensil width is advisable, the invagination of aluminium armor tape tail head between the gold utensil of adorning and the aluminium conductor contact surface.

The utility model is on the basis that does not change the original performance of aluminium armor tape; Increase the friction force of smooth aluminum lead and iron material matter gold utensil, reduced the probability that iron material matter gold utensil displacement takes place or gets loose, reduced the line maintenance number of times; Circuit daily attention cost is reduced, guaranteed the safe operation of circuit.

Description of drawings Fig. 1 is the cross section view of the utility model;

Fig. 2 is the perspective view of the utility model.

The specific embodimentFurther introduce the embodiment of the utility model below in conjunction with accompanying drawing.

Like Fig. 1, shown in Figure 2, this aluminium armor tape is made up of with outer coarse surface layer 4 interior aluminium strip layer 2, and interior aluminium strip layer 2 thickness are 1mm or are slightly larger than 1mm that width is 10mm, is determined the coiling length of aluminium armor tape by the diameter of width that is loaded on the gold utensil 3 on the lead and aluminium conductor 1.

The outer coarse surface layer 4 of this aluminium armor tape can form through following dual mode:

First kind of mode is under the situation that does not change the original specification of aluminium armor tape; Sticking one deck granular substance that is coated with on the aluminium strip layer 2 in aluminium armor tape; The sticking granular substance that is coated with is a silicon-carbide particle; Only be distributed on two outside faces up and down of interior aluminium strip layer 2 of said aluminium armor tape, form rough outer coarse surface layer 4, the side keeps smooth cut surface.Two outside face silicon-carbide particles are sticking up and down is coated with thickness and is not more than 0.5mm.

The second way is suitably to increase the aluminium armor tape calculated thickness; By 1mm or be slightly larger than 1mm thickness and increase to 1.5mm or be slightly larger than 1.5mm; Pass through mechanical grinding; The 0.5 mm thick aluminium material that is not more than having more on average respectively is polished into uneven on two surfaces up and down, i.e. each polishing of upper and lower surface by interior aluminium strip layer is not more than 0.25mm thickness, thereby forms and the corresponding outer coarse surface layer 4 of first kind of mode.

During on-site installation, aluminium armor tape carries out on aluminium conductor earlier, twines along outer aluminium conductor 1 intrinsic coiling direction; Every circle should be tried one's best closely during winding, and coiling length suitably relaxes greater than its width with adorned gold utensil 3 width is advisable, and redundance is cut; Aluminium armor tape tail head should fold between the gold utensil of adorning 3 and aluminium conductor 1 contact surface; At last gold utensil is enclosed within on the outer coarse surface layer 4 of aluminium armor tape, and fixes, accomplish and install with bolt.
