Abstract
The utility model discloses a pre-winding T-shaped connecting strip for leads with different diameters. The connecting strip includes two helical pre-winding sheets, conductive sands are adhered to the inner walls of the pre-winding sheets, the pre-winding sheets are formed by pasting a plurality of alloy leads which have a same diameter and are pre-prepared into helical shape, and each of the pre-winding sheets is folded to a right angle at the middle part. The pre-winding T-shaped connecting strip for leads with different diameters is used for connecting a down-lead with a small diameter and a main lead with a big diameter, achieving electrical conduction. The pre-winding T-shaped connecting strip for leads with different diameters is winded at the outside of the main lead and the down-lead, and the internal diameter of the pre-winding T-shaped connecting strip is less than the external diameter of a winded lead, ensuring an enough clenching force; the clenching force generated by the pre-winding T-shaped connecting strip is applied to leads uniformly without stress concentration; the total cross sectional area of the pre-winding T-shaped connecting strip is far greater than that of a small lead, ensuring enough flow conductivity; and the pre-winding T-shaped connecting strip can be installed by hand, and operation is convenient.
Description
Technical field
The utility model relates to the T ﹠ D Technology field, particularly relates to a kind of non-isometrical wire with preformed T shape connecting strip.Utilize this connecting strip can carry out main line to the continuing of downlead, downlead is fixed on the main line, and realize electrically conducting between downlead and main line.
Background technology
Along with the development of China's T ﹠ D Technology, more and more higher to the performance requirement of power equipment.In the time need to drawing less wire downwards from the main line, equipment commonly used is parallel groove clamp or T-shape cable clamp now.These two kinds of equipment all need by bolted, and fastening torque of bolt is wayward.Tightening moment is excessive, the easy damaged wire; Tightening moment is too small, then can get loose, slippage.In addition, parallel groove clamp and T-shape cable clamp are generally casting aluminium material, are control weight, and so small volume is little with the contact area of wire.If Torque Control is improper, problem overheated even broken string very easily occurs.Top-twisted wire-clip is even to the grip force of wire, and the water conservancy diversion area is large, can solve the problem of traditional wire clamp.Also there is producer to design preformed T shape connecting strip, but all connects for the T between the equal diameter wire, can't realize continuing of different-diameter wire.
The utility model content
The utility model provides a kind of non-isometrical wire with preformed T shape connecting strip, exists conventional method easily to break down in the prior art and problem that non-isometrical wire can not continue with preformed connecting strip in order to solve.
For reaching above-mentioned purpose, on the one hand, the utility model provides a kind of non-isometrical wire with preformed T shape connecting strip, and described connecting strip comprises 2 spiral helicine preformed armor rods sheets, and every described preformed armor rods sheet is identical and be prefabricated into spiral helicine B alloy wire and paste and form by the several wire footpath.
Further, described every preformed armor rods sheet is curved orthogonal shape in the centre, and the spiral internal diameter d1 in A district, both sides, right angle is greater than the spiral internal diameter d2 in B district.。
Further, every described preformed armor rods sheet adopts aluminum-alloy wire.
Further, described every preformed armor rods sheet internal diameter is stained with conduction sand.
Further, described connecting strip is wound in outside the wire.
Further, the inner diameter d 1 of described connecting strip, d2 are respectively less than wire diameter D, d.
Further, described connecting strip is made color mark S at B district external diameter.
The utility model beneficial effect is as follows:
A kind of non-isometrical wire of the utility model embodiment has guaranteed that with preformed T shape connecting strip the T between the different-diameter wire connects; Continuing the position can electrochemical corrosion, extension lead useful life; The internal diameter of preformed connecting strip is less than the external diameter of wire, and internal diameter is stained with conduction sand, can guarantee connecting strip to the enough grips of wire and water conservancy diversion area, guarantees to continue intensity and electric property; Preformed T shape connecting strip is easy for installation, only needs connecting strip can be finished installation along the wire winding.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, does not limit the utility model.
A kind of non-isometrical wire that the utility model embodiment relates to is a kind of power transmission and transformation system electric armour clamp with preformed T shape connecting strip (hereinafter to be referred as connecting strip), is drawing the downlead use downwards from main line.
As shown in Figure 1, every preformed armor rods sheet is identical and be prefabricated into spiral helicine B alloy wire and paste and form by the several wire footpath, and every preformed armor rods sheet is curved mutually vertical right-angle side in middle C district, and the inner diameter d 1 of A district helix is greater than the inner diameter d 2 of B district helix.The B alloy wire of making the preformed armor rods sheet adopts aluminum-alloy wire; The internal diameter of every preformed armor rods sheet is stained with conduction sand.Every preformed armor rods sheet by subterminal position, is processed with firmly color mark S in the helix outside at B district helix, clearly representing this end as small end, and the mark S alignment on two preformed armor rods sheets when requiring to install.
As shown in Figure 2, the non-isometrical wire of a cover is comprised of two such preformed armor rods sheets with preformed T shape connecting strip.
Connecting strip A district is installed on the large diameter main line, and the B district is installed on the downlead of minor diameter.The inner diameter d 1 in connecting strip A district is slightly less than the outer diameter D of main line, and the inner diameter d 2 in B district is slightly less than the outside diameter d of downlead.The preformed connecting strip that installs as shown in Figure 3.
