Description
Technical field
The utility model belongs to cable application field, and in particular to a kind of new harbour medium-voltage drum cable.
Background technology
Cable is typically by several or the cable of similar rope that several groups of conducting wires [every group at least two] are twisted, every group
Mutually insulated between conducting wire, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation.Multi rack is located at
In the air or mounted in underground, the bottom, for telecommunication or power Transmission.1832, tsarist Russia's army officers were permitted woods lattice and are buried telegraphy line
Each other with, with being placed in glass tube, here it is an earliest in the world undergrounds after rubber-covered between underground, six conductors
Cable.
And with Chinese society expanding economy, the requirement to cable also becomes higher therewith, for special circumstances, it is necessary to consider
Cable has the function of soaking for certain tensile capacity, bending resistance and cold-proof, anti-seawater in itself, i.e., is passed through to cable under temperature
It pulled, bent, continuous thousands of times or even up to ten thousand times, cable is maintained to normal operation conductor and does not break, insulate
It does not also crack with sheath material, the performances such as also require cable that there is high intensity, cold-resistant, oil resistant, block water.
The content of the invention
The purpose of this utility model is that in a kind of new harbour reel for solving above-mentioned prior art problem and providing
Voltage cable.
A kind of new harbour medium-voltage drum cable, including cable body, the cable body is by cable core, enhancement layer and outer
Sheath forms；The cable core is in flat；It is made of in the cable core 4-6 group conductors；Fibre coatings are extruded outside the cable core；
Gap in the fibre coatings is filled with the expansion cream that blocks water；Enhancement layer is extruded outside the fibre coatings；On the cable core
Under be provided at both ends with reinforcing rib；The reinforcing rib is arranged between cable core and enhancement layer；Strengthening core is provided in the enhancement layer；
Shielded layer is extruded outside the enhancement layer；Oversheath is extruded outside the shielded layer.
A kind of above-mentioned new harbour medium-voltage drum cable, the strengthening core extrude interior shield outside using load-bearing resistance to compression wire drawing
It covers；The quantity of the strengthening core is four.
A kind of above-mentioned new harbour medium-voltage drum cable, the inner sheath oversheath be by ethylene-propylene diene copolymer be base-material
Low smoke and zero halogen rubber material be made.
The beneficial effects of the utility model：The structure design of the utility model is reasonable, has good tension and bending property,
The reinforcing rib of setting can be very good to influence from external force inside protection cable core.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific embodiment
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not form to this reality
With new any restrictions.
In the description of the utility model, it is necessary to explanation, term " center, upper and lower, left and right, it is vertical, horizontal, interior,
The orientation of instructions or position relationship are based on orientation shown in the drawings or position relationship outside " etc., are for only for ease of and describe this reality
There must be specific orientation, with device that is simplifying description rather than instruction or hint meaning or element with specific with new
Azimuth configuration and operation, therefore it is not intended that limitation to the utility model, term " first, second, third " only limits in addition
It is acted in description, and it is not intended that instruction or hint relative importance.
, it is necessary to which explanation, unless explicitly stated or limits in the description of the utility model, term " installation,
It is connected, connection " it should broadly understood, such as：Can be fixedly connected or be detachably connected or integrally connected, it can be with
It is mechanical connection or electrical connection, can be directly connected, can also be indirectly connected by intermediary, can be two
Connection inside a element.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood in this reality
With the concrete meaning in new.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of new harbour medium-voltage drum cable, including
Cable body 1, the cable body 1 are made of cable core 2, enhancement layer 3 and oversheath 4；The cable core 2 is in flat；The cable
It is made of in core 2 4-6 groups conductor 5；Fibre coatings 6 are extruded outside the cable core 2；Gap filling in the fibre coatings 6
Block water expansion cream 7；Enhancement layer 3 is extruded outside the fibre coatings 6；2 upper and lower ends of cable core are provided with reinforcing rib 8；Institute
Reinforcing rib 8 is stated to be arranged between cable core 2 and enhancement layer 3；Strengthening core 9 is provided in the enhancement layer 3；It is squeezed outside the enhancement layer 3
Bag shielded layer 10；Oversheath 4 is extruded outside the shielded layer 10.
The strengthening core 9 extrudes inner sheath 12 outside using load-bearing resistance to compression wire drawing 11 and forms；The quantity of the strengthening core 9 is four
Root.
The inner sheath 12 and oversheath 4 are made of ethylene-propylene diene copolymer of the low smoke and zero halogen rubber material of base-material.
Inner/outer sheath is with high tensile, cold-resistant, oil resistant, the ethylene-propylene diene copolymer to block water（034）Material is made, so mechanical
Intensity is high, and the load-bearing enhancement layer of another aspect cable adds the torsional resistance of cable, because aramid fiber silk fiber is braiding knot
Structure has that left-hand is wrapped and dextrad is wrapped, so cable is distorted in left-hand and anti-twist, cable body is all played the role of in dextrad distortion
Strengthening core is inside additionally provided with, greatly improves the anti-pressure ability of cable body.
The preferred embodiment of the utility model described in detail above, but the utility model is not limited to above-mentioned implementation
Detail in mode in the range of the technology design of the utility model, can carry out the technical solution of the utility model
A variety of equivalents, these equivalents belong to the scope of protection of the utility model.
