Abstract

The utility model discloses a flat watertight cable used for underwater frequent movement, comprising a flat outer casing and aramid ropes. A plurality of cabling groups are symmetrically distributed in the outer casing, with a transverse center as an axis; each cabling group is composed of a plurality of cabling wires and successively includes center layers, insulating layers, a lapping layer, a shielding layer and an inner jacket from inside to outside; the central layers and the insulating layers covered on the central layers form varnished wires. The cabling groups comprise cabling groups D, cabling groups C and cabling groups B which are successively arranged from the outer casing inner center to two ends; the aramid ropes are symmetrically distributed at two ends of the outer casing. The cabling groups are symmetrically distributed with a center line as a reference and two sides are reinforced by employing the aramid ropes, thereby ensuring good tensile performance of cables; the outer casing employs extraordinary silicone rubber, thereby ensuring watertightness performance, wear-resisting property and bending performance of cables.

Description

A kind of flat watertight cable for frequently moving under water

Technical field

The utility model relates to a kind of cable, particularly a kind of flat watertight cable for frequently moving under water.

Background technology

In recent years, maintaining sustained and rapid growth of China's economy, for wires and cables industry provides the huge market space, the kind of cable is more and more, wherein the scope of submerged cable application is also more and more wider, and existingly for frequent mobile cable under water, does not almost have, and its reason is: the cable that meets instructions for use under frequent mobile environment under water, should cable soft, also must there is good watertightness performance, tensile property and good fatigue performance.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides the flat watertight cable for frequently moving that a kind of watertightness performance is good, tensile property is strong, fatigue performance is good under water.

The technical scheme that the utility model addresses the above problem is: a kind of flat watertight cable for frequently moving under water, the outer protecting shell that comprises flat, described outer protecting shell inside take transverse center as axial symmetry is distributed with a plurality of one-tenth cable set, described one-tenth cable set becomes cable to form by some, described one-tenth cable comprises central core, insulating barrier, lapping layer, screen and the sheath consisting of conductor from inside to outside successively, and described central core and the insulating barrier being wrapped in outside central core form enamelled wire jointly.

Described one-tenth cable set comprises into cable set B, becomes cable set C and become cable set D.

Described one-tenth cable set D, become cable set C and become cable set B to be arranged in order to two ends from described outer protecting shell inside center.

The described flat watertight cable for frequent movement under water also comprises aramid fiber rope, and aramid fiber rope is symmetrically distributed in the two ends of outer protecting shell.

Described one-tenth cable set B becomes cable to form by two, in the stranding wire-wound covering of one-tenth cable set B, is evenly provided with 7 enamelled wires.

In the stranding wire-wound covering of described one-tenth cable set C, be evenly provided with 3 enamelled wires.

In the stranding wire-wound covering of described one-tenth cable set D, be evenly provided with 2 enamelled wires.

Described outer protecting shell is silicon rubber oversheath.

Described screen is formed by tinned copper wire braiding.

Described sheath adopts cross-linked polyolefin to extrude and forms.

The beneficial effects of the utility model are: one-tenth cable set of the present utility model be take outer protecting shell center line and is symmetric as benchmark, two ends adopt aramid fiber rope to strengthen, guaranteed that cable has good tensile property, outer protecting shell adopts special silicone rubber, has guaranteed watertightness performance, anti-wear performance and the bending property of cable.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, the utility model comprises the outermost outer protecting shell 6 that is flat, described outer protecting shell 6 is special, wear-resistant tear-proof silicon rubber oversheath, take transverse center and be distributed with aramid fiber rope A and become cable set B as axial symmetry in described outer protecting shell 6 inside, become cable set C, become cable set D, aramid fiber rope A is the aramid fiber rope that aramid fiber yarn forms after stranded, described one-tenth cable set comprises central core 1 from inside to outside successively, insulating barrier 2, lapping layer 3, screen 4 and sheath 5, described central core 1 is conductor, cross-sectional area of conductor is 0.3mm2, conductor structure is 19/0.14 regular lay configuration, at the outer extruded insulation layer 2 of central core 1, insulation nominal thickness is 0.25mm, and this thickness both can guarantee insulation property, again can proof strength, for alleviating cable weight, also play a role, insulating barrier 2 is outer for adopting the lapping layer 3 of the wrapped composition of polyester film, the outer screen 4 being woven into for diameter 0.1mm tinned copper wire of lapping layer 3, all litzendraht wire density of screen 4 are all not less than 85%, be not more than 88%, so both can guarantee cable shield effect, and can play again and reduce the effect of cable weight, outside screen 4, for cross-linked polyolefin, extrude the sheath 5 of composition.

Described central core 1 and the insulating barrier 2 being wrapped in outside central core 1 form enamelled wire jointly, as shown in Figure 2, described one-tenth cable set B becomes cable to form by two, in the stranding wire-wound covering of one-tenth cable set B, be evenly provided with 7 enamelled wires, as shown in Figure 3, in the stranding wire-wound covering of described one-tenth cable set C, be evenly provided with 3 enamelled wires, as shown in Figure 4, in the stranding wire-wound covering of described one-tenth cable set D, be evenly provided with 2 enamelled wires.

Below be only preferred embodiment of the present utility model, according to above-mentioned design of the present utility model, those skilled in the art also can make to this various modifications and conversion.For example, the enamelled wire radical between insulating barrier and lapping layer is revised and conversion, and the modification of making in the situation that not departing from the utility model flesh and blood all belongs to the scope of the utility model protection.
