Description

A kind of elastic body insulated jacketed cable

Technical field

It the utility model is related to field of cable technology, and in particular to a kind of elastic body insulated jacketed cable.

Background technology

Cable for wind power generation as wind power plant auxiliary products becomes the cable for having huge market potential New varieties, by numerous cable enterprise developments and have been launched.But for the huge cable for wind power generation in market, both do not have at present There are country and professional standard also without unified technical specification, each enterprise does things in his own way, its structure size of the cable of manufacture will The material ask, used and requirement, voltage class, use environment temperature, specification section, use occasion, test method etc. are not It is unified, it is very lack of standardization, to the selection of user and using bringing very big trouble, and due to no country and professional standard, Product requirement is lack of standardization, and product quality is very different, and there are no laws to abide by for market surpervision, and a large amount of cables unqualified or inferior are full of city , only user does not bring unnecessary economic loss, also very big hidden to be brought using the equipment safety operation of cable Suffer from, serious threat the safety of electrical control equipment, the normal operation of electric system and personal property.

At present, the flow of wind-power torsion-resistant song flexible cable：Copper wire be twisted → insulate extrude → Spark plug optical fiber sensor → insulated wire cores into Cable is twisted → and sheath extrudes → cable product inspection.Occur cable cover(ing) bulge, conductor open circuit, insulation during the cable long-time service Deformation.Wind energy generating plant frequently uses, the cable lower excessive fatigue under the action of twisting resistance and gradually deform, so generally Wind energy cable be difficult for a long time use.With the difference of wind speed, the requirement to supporting cable is very different, because wind Can gather very big stress in machine operational process, inside cable, the torsional stress in cable can bigger, traditional cable is used for such After wind turbine.Because torsional stress cannot be eliminated or alleviated in time, and the core that frequently breaks.

Utility model content

The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provides a kind of elastic body insulated shield Cover cable

Technical solution is used by realize the purpose of this utility model：

A kind of elastic body insulated jacketed cable, including conductor and extrusion are coated on the elastic insulating layer outside the conductor, There is strengthening core made of Polyester Fibers between multiple conductors, it is multiple described to be coated with the conductor of elastic insulating layer by outer The elastomeric material extrusion of layer is coated on internal and is in close contact with the strengthening core, and the elastomeric material of the outer layer forms bullet Property inner sheath, the outside of the elasticity inner sheath is equipped with braiding layer, and the braiding layer outside is extruded overmolded by elastomer Flexible oversheath.

The braiding layer is fiber braiding layer.

The conductor is copper wire, the filament diameter 0.2mm of the copper wire.

The utility model is provided at an outer portion with by extruding cladding elastic insulating layer outside conductor and extrudes overmolded interior shield Set, by extruding overmolded oversheath by braiding layer bag in the outside of inner sheath outside inner sheath, not only so that conductor with absolutely The connection of edge body is even closer, and flexibility and pultrusion performance are also further enhanced, and bending property is more preferable, especially suitable Matched together in wind power plant.

Brief description of the drawings

Fig. 1 is the structure diagram of elastic body insulated jacketed cable.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place The specific embodiment of description only to explain the utility model, is not used to limit the utility model.

It is shown in Figure 1, a kind of elastic body insulated jacketed cable, including the conductor 4 of four rectangular shapes arrangements and squeeze Go out the elastic insulating layer 5 being coated on outside the conductor, there are strengthening core 6 made of Polyester Fibers between multiple conductors 4, Multiple conductors 4 for being coated with elastic insulating layer 5 by the elastomeric material extrusion of outer layer be coated on it is internal and with the reinforcement Core is in close contact, and the elastomeric material of the outer layer forms elastic inner sheath 3, and the outside of the elasticity inner sheath is equipped with braiding layer 2, overmolded flexible oversheath 1 is extruded in the braiding layer outside by elastomer.

Wherein, the braiding layer is fiber braiding layer, can use carbon fiber, glass fibre, one kind of basalt fibre. In order to strengthen tensile property, steel wire or copper wire woven layer can also be used.

Wherein, the conductor is copper wire, the filament diameter 0.2mm of the copper wire.

Elastic insulating layer, elastic outer sheath and the elastic inner sheath, can use polyolefin alloy thermoplastic elastic Body TPV thermoplastic extrusions are formed in the outside of conductor.

For the utility model using flexibility is elastic body insulated and sheath material, when extrusion, uses fashion of extrusion, make insulation and Sheath is closer, and it is difficult to slide that conductor and core squeeze pipe mode than common PVC material when in use, is conducive to mobile use.

Preferably, the inscribed circle of the elastic inner sheath 3 is to the distance of circumcircle and the consistency of thickness of the oversheath, institute Elastic inner sheath 3 is stated in shaping, together extrudes the elastic insulating layer 5 that the conductor and extrusion are coated on outside the conductor Cladding, the gap of conductor on the outside is filled together, and is formed elastomer-filled, is set filler without other, is reduced life Into cost of manufacture.

The utility model has good weatherability, bendability, oil resistivity etc., more superior in laying and performance； In low temperature using occurring without brittle cracking phenomena；Bending property is more preferable than common PVC product, and bending radius smaller, reduces 5 Times or so；Being capable of the term use in oil pollution environment.

The utility model uses filament stranded conductor, and when stranding uses less lay ratio, is produced than common PVC electric wire Product are more soft, and bending property is more preferable.

In short, the utility model coats elastic insulating layer by being extruded outside conductor, and it is overmolded to be provided at an outer portion with extrusion Inner sheath, by extruding overmolded oversheath by braiding layer bag in the outside of inner sheath outside inner sheath, not only so that leading The connection of body and insulator is even closer, and flexibility and pultrusion performance are also further enhanced, and bending property is more preferable, Matched particularly suitable for wind power plant.

The above is only the preferred embodiment of the utility model, it is noted that for the general of the art For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change The scope of protection of the utility model is also should be regarded as into retouching.
