Technical field

The utility model relates to a kind of special cable, it is exhausted to belong to polyether sulfone for especially a kind of polyether sulfone insulation special cable Edge special cable technical field.

Background technique

Special cable is that have specific use, and the cable that can be used under some extreme conditions generally comprises high temperature resistant, resistance to Soda acid, termite-proof, the cable of the performances such as swelling resistance, polyether sulfone are a kind of comprehensive performance of Britain's ICI Company in exploitation in 1972 Excellent thermoplastic macromolecule material is one of the special engineering plastics few in number being applied at present.It has excellent Heat resistance, physical mechanical property, insulation performance etc., especially have can be used continuously at high temperature and temperature sharply Outstanding advantages of retention property is stablized is remained in the environment of variation, but since polyether sulfone flexibility itself is inadequate, is caused existing Polyether sulfone special cable flexibility it is poor.

Utility model content

The purpose of this utility model: in view of the deficiencies of the prior art, it is extraordinary that the utility model provides a kind of polyether sulfone insulation Cable can effectively improve the flexibility of polyether sulfone special cable.

To achieve the goals above, the utility model adopts the following technical solution:

A kind of polyether sulfone insulation special cable, including battery core, the battery core are enclosed with the first polyether sulfone covering by several Wire stranding form, battery core is wrapped with flexible insulating layer, is provided with shielded layer outside flexible insulating layer, the shielded layer is by gold Belong to silk to work out, shielded layer is wrapped with the second polyethersulfon layer.

Further, the battery core center is equipped with flexible reinforced core.

Further, the flexible reinforced core includes the wirerope being twisted by finer wire, and wirerope is wrapped with rubber Glue-line.

Further, the flexible insulating layer is any one in vulcanized rubber or EP rubbers.

Further, the material for the wire that the shielded layer uses is any one in aluminium or copper.

Further, second polyethersulfon layer with a thickness of 0.2-0.8mm.

The beneficial effects of the utility model are:

1, the wire stranding that battery core is enclosed with the first polyether sulfone covering by several in the utility model forms, and has flexibility Well, the advantages of heat resisting temperature height, long service life；

2, battery core center is equipped with flexible reinforced core in the utility model, and flexible reinforced core includes being twisted by finer wire Wirerope can be improved the tensile strength of the utility model；

3, it is enclosed on conducting wire in the utility model on the first polyether sulfone covering and wirerope and is enclosed with rubber layer, so that electric There is certain elasticity between core and flexible reinforced core, can allow for the deformation for having certain between battery core and flexible reinforced core, thus So that the utility model is more flexible.

It is excellent that in conclusion the utility model has, flexibility is good, heat-resist, good corrosion resistance and tensile strength are high Point.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of battery core in Fig. 1；

Wherein, 1, battery core, the 2, first polyether sulfone covering, 3, conducting wire, 4, flexible insulating layer, 5, shielded layer, the 6, second polyethers Sulfone layer, 7, finer wire, 8, rubber layer.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

A kind of polyether sulfone insulate special cable, including battery core 1 in the utility model referring to FIG. 1-2, the battery core 1 by Several conducting wires 3 for being enclosed with the first polyether sulfone covering 2 are twisted, and battery core 1 is wrapped with flexible insulating layer 4, flexible insulation It is provided with shielded layer 5 outside layer 4, the shielded layer 5 is worked out by wire, and shielded layer 5 is wrapped with the second polyethersulfon layer 6.

In the present embodiment, 1 center of battery core is equipped with flexible reinforced core；The flexible reinforced core includes by finer wire 7 The tensile strength of the utility model can be significantly increased in the wirerope being twisted, and wirerope is wrapped with rubber layer 8, Neng Goufang Only the first polyether sulfone covering 2 outside wirerope direct friction conducting wire 3, avoid the first polyether sulfone covering 2 wear the case where；It is described soft Property insulating layer 4 be vulcanized rubber, have good flexibility, insulating properties and wearability；The wire that the shielded layer 5 uses Material is copper, has the advantages that shield effectiveness is good；Second polyethersulfon layer 6 with a thickness of 0.2-0.8mm, can guarantee this reality With novel whole flexibility, at the same the utility model is had wearability is good, heat resisting temperature is high, acid-alkali-corrosive-resisting and resistance to The good advantage of swellability.

The utility model is when implementing:

When energization, the first polyether sulfone covering 2 being wrapped on conducting wire 3 is easiest to receive the heat of the sending of conducting wire 3, but by In the first polyether sulfone covering 2 have very high heat resistance, 180-200 DEG C of long-term use temperature.Ageing-resistant performance is excellent, 180 DEG C using up to 20 years.The good of flame resistance not smoke burning.Creep resistant is good, answering under 150 DEG C and 20MPa pressure Become only 2.55%, so that the utility model is able to bear very high temperature, has more safety；It is wrapped in the utility model most Second polyethersulfon layer 6 of outer layer primarily serves effect that is wear-resisting, preventing acid and alkali corrosion, anti-swelling.

It is excellent that in conclusion the utility model has, flexibility is good, heat-resist, good corrosion resistance and tensile strength are high Point.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
