Description

A kind of harbour flat cable that low temperature resistant tension is anti-aging

Technical field

The utility model belongs to field of cable technology, and in particular to a kind of flat electricity in harbour that low temperature resistant tension is anti-aging Cable.

Background technique

Currently, urban and rural power network construction and renovation is dig-inned by many enterprises, and the enterpriser of some clevernesses is eye Light is put farther, aims at Communication construction market, especially Port Construction Projects.Recently the market investigating datas issued shows, port Mouth construction cable market contains good business opportunity, and is a huge wire and cable city.Investigation shows that China is planning It is self-evident with regard to the dosage of its cable in the coastal and many major ports of inland river watershed construction.It is introduced that port construction electricity consumption Cable, mainly harbour construction power transmission and distribution power cable, the interim distribution cable in building site and light conduits, communication cable, harbour machine Tool cable etc..According to the natural conditions in harbour building site, it is desirable that cable used has the mechanicalnesses such as resistance to dragging, drawing, impact Can, while requiring safe and reliable leakproof.

Utility model content

A kind of low temperature resistant tension provided utility model aims to solve above-mentioned prior art problem is anti-aging Harbour flat cable.

A kind of harbour flat cable that low temperature resistant tension is anti-aging, including cable body, the cable body is by three groups of cables Core and the sheath being extruded in outside cable core form；Three cable core parallel equidistants are placed in sheath；Setting inside the cable core For conductor；The first polyester layer and the second polyester layer are surrounded with outside the conductor；First polyester layer and the second polyester Butyronitrile polyvinyl chloride composite insulating layer is provided between belt；Combined knitting layer is extruded with outside second polyester layer；Institute It states and is surrounded with third polyester belt outside combined knitting layer；Sheath is extruded with outside the third polyester belt.

Sleeping berth in a kind of above-mentioned reversible heavy truck, the combined knitting layer are interlocked by copper wire and cotton synthetic fibre fibrous material It weaves.

Sleeping berth in a kind of above-mentioned reversible heavy truck, the sheath are made of butyronitrile polyvinyl chloride composite.

The utility model has the beneficial effects that the utility model conductor uses the 5th kind of annealed copper conductor, when conductor strand in The heart, as reinforcing element, improves the tensile property of conductor using nylon fibre, while lesser lay ratio is used when conductor strand, Improve the bending property and softness of cable.

Be surrounded with three layers of polyester belt outside the utility model conductor, prevent it is insulating exruded during led because extrusion pressure is big Insulation embedded conductor gap is caused, guarantees cable softness and bending property, and can prevent the burr of conductor or burr from stabbing Insulation.

The braiding layer that the utility model has copper wire and nylon fibre composite structure to constitute outside every insulated wire cores, metal It is identical with nylon fibre number of spindles, contrary.Copper-wire braided layer can double as ground wire, and only for ground connection, electricity can be improved in nylon fibre The tensile property of cable, and the bending property of cable is not influenced because weaving copper wire.

The utility model ground wire is arranged outside insulated wire cores with type of weave, and the construction of cable is stablized, and reduces cable Outer diameter, do not have to occupy much room, be well suited for harbour machinery use.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model.

Specific embodiment

The utility model is described in further detail for embodiment in reference to the accompanying drawing, but does not constitute to this reality With novel any restrictions.

In the description of the present invention, it should be noted that term " center, upper and lower, left and right, it is vertical, horizontal, interior, The orientation or positional relationship of instructions is to be based on the orientation or positional relationship shown in the drawings outside " etc., is merely for convenience of describing this reality It is described with novel with simplified, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific Orientation construction and operation, therefore should not be understood as limiting the present invention, furthermore term " first, second, third " only limits It is acted in description, is not understood to indicate or imply relative importance.

In the description of the present invention, it should be noted that unless explicitly stated or limit, term " installation, It is connected, connection " it should broadly understood, such as: it may be a fixed connection, may be a detachable connection or integrally connected, it can be with It is mechanical connection, is also possible to be electrically connected, can be directly connected, two can also be can be indirectly connected through an intermediary Connection inside a element.For the ordinary skill in the art, above-mentioned term can be understood in this reality with concrete condition With the concrete meaning in novel.

Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of flat electricity in harbour that low temperature resistant tension is anti-aging Cable, including cable body 1, the cable body 1 are made of three groups of cable cores 2 and the sheath 3 being extruded in outside cable core 2；Described three 2 parallel equidistant of cable core is placed in sheath 3；Conductor 4 is set as inside the cable core 2, conductor is led using the 5th kind of annealed copper Body, the tensile property of conductor is improved as reinforcing element using nylon fibre in center when conductor strand, while adopting when conductor strand With lesser lay ratio, the bending property and softness of cable are improved；5 He of the first polyester layer is surrounded with outside the conductor 4 Second polyester layer 6；It is exhausted that butyronitrile polyvinyl chloride composite is provided between first polyester layer 5 and the second polyester layer 6 Edge layer 7；It is extruded with combined knitting layer 8 outside second polyester layer 6, the combined knitting layer 8 is by copper wire and cotton synthetic fibre fiber Material weaving forms；Third polyester belt 9 is surrounded with outside the combined knitting layer 8；Shield is extruded with outside the third polyester belt 9 Set 3, the sheath are made of butyronitrile polyvinyl chloride composite.

Three layers of polyester belt are surrounded with outside conductor, prevent it is insulating exruded during cause insulation to be embedded in because extrusion pressure is big Connector slots guarantee cable softness and bending property, and can prevent the burr of conductor or burr from stabbing insulation.

The braiding layer that the utility model has copper wire and nylon fibre composite structure to constitute outside every insulated wire cores, metal It is identical with nylon fibre number of spindles, contrary.Copper-wire braided layer can double as ground wire, and only for ground connection, electricity can be improved in nylon fibre The tensile property of cable, and the bending property of cable is not influenced because weaving copper wire.

The utility model ground wire is arranged outside insulated wire cores with type of weave, and the construction of cable is stablized, and reduces cable Outer diameter, do not have to occupy much room, be well suited for harbour machinery use.

Preferred embodiments of the present invention are described in detail above, but the utility model is not limited to above-mentioned implementation Detail in mode can carry out the technical solution of the utility model in the range of the technology design of the utility model A variety of equivalents, these equivalents belong to the protection scope of the utility model.
