Description
Technical field
This utility model relates to a kind of earth lead, a kind of copper pigtail earth lead.
Background technology
In power construction, owing to high tension cable only has three cores, there is no the neutral conductor, operationally can the three characteristics of the middle term uneven and produce faradic current, therefore outside the steel sheath of hv cable termination head, all can fix an earth lead, faradic current can be allowed to pass through the incoming the earth of earth lead.Earth lead in use is the most all copper pigtail earth lead at present, this earth lead uses copper stranded conductor or copper litz wire as middle conductor section, and these middle conductor section two ends are all crimped with copper pipe as jointing, there is feature light, that conductivity is high, anti-fatigue ability is strong.But in use find, owing to the middle conductor section of the sub-earth lead of current copper pigtail is the copper pigtail net of a whole piece straightway, quality is soft, and the outdoor termination of high tension cable is that long-time exposure is aerial, the use time one is long afterwards, hydrone in air can permeate along copper pigtail net at leisure inward, finally arrive high tension cable copper shield and semi-conductive layer, not only the safe operation to high tension cable leaves hidden danger, and greatly reduces service life and the service life of copper pigtail earth lead itself of high tension cable.
Utility model content
For the problems referred to above, the problem that this utility model intends to solve be to provide a kind of rational in infrastructure, water-impervious performance is good, safe and reliable and the copper pigtail earth lead of length in service life.
For reaching above-mentioned purpose, this utility model is by the following technical solutions: a kind of copper pigtail earth lead, including earth lead body, described earth lead body includes middle conductor section and is fixed on the jointing at these middle conductor section two ends, described middle conductor section includes canned paragraph, water-impervious section and transition linkage section, described water-impervious section is positioned between described canned paragraph and described transition linkage section, described canned paragraph, the material of described water-impervious section and described transition linkage section is copper stranded conductor or copper litz wire, the shape of described canned paragraph and described transition linkage section is linear, described water-impervious section be shaped as Curved, and it is additionally provided with tin coating in described water-impervious section, the length of described canned paragraph is provided with 8cm, the length of described water-impervious section is provided with 5cm.
As preferably, described water-impervious section be shaped as S-shaped.
The beneficial effects of the utility model: this utility model has carried out unique design to its middle conductor segment, especially water-impervious section has been carried out curved design and tin plating design, the wherein tin plating design of water-impervious section, the most soft tin plating solidification of water-impervious section can be made, so that the hydrone in air cannot slowly penetrate into high tension cable copper shield and semi-conductive layer along middle conductor section, the safe operation of high tension cable is effectively ensured, add the design of curved shape, stop the hydrone infiltration in air further, furthermore canned paragraph and water-impervious section have been carried out rational size design, its entirety is made to have rational in infrastructure, water-impervious performance is good, safe and reliable and the feature of length in service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-middle conductor section, 2-jointing, 3-canned paragraph, 4-water-impervious section, 5-transition linkage section.
Detailed description of the invention
In order to make those skilled in the art be better understood from this utility model scheme, below in conjunction with the accompanying drawing in the present embodiment, the technical scheme in this utility model embodiment is carried out clear, complete description.
As shown in Figure 1, the utility model discloses a kind of copper pigtail earth lead, including earth lead body, earth lead body includes middle conductor section 1 and is fixed on the jointing 2 at these middle conductor section 1 two ends, middle conductor section 1 includes canned paragraph 3, water-impervious section 4 and transition linkage section 5, water-impervious section 4 is between canned paragraph 3 and transition linkage section 5, canned paragraph 3, the material of water-impervious section 4 and transition linkage section 5 is copper stranded conductor or copper litz wire, the shape of canned paragraph 3 and transition linkage section 5 is linear, water-impervious section 4 be shaped as Curved, and it is additionally provided with tin coating in water-impervious section 4, the length of canned paragraph 3 is provided with 8cm, the length of water-impervious section 4 is provided with 5cm, water-impervious section 4 be shaped as S-shaped.
This utility model has carried out unique design to its middle conductor segment 1, especially water-impervious section 4 curved design and tin plating design are carried out, the wherein tin plating design of water-impervious section 4, the most soft tin plating solidification of water-impervious section 4 can be made, so that the hydrone in air cannot slowly penetrate into high tension cable copper shield and semi-conductive layer along middle conductor section 1, the safe operation of high tension cable is effectively ensured, add the design of curved shape, stop the hydrone infiltration in air further, furthermore canned paragraph 3 and water-impervious section 4 have been carried out rational size design, its entirety is made to have rational in infrastructure, water-impervious performance is good, safe and reliable and the feature of length in service life.
Obviously, described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all should belong to the scope of this utility model protection.
