Description
Technical field
The utility model belongs to power cable technical field, is specifically related to a kind of plastic and flexible foam matter filler.
Background technology
The primary structure of present cable is made up of cable core and sheath, core cross section is mostly circular, there is space by between the core that stranding is adjacent, because space can affect the compactness of the construction of cable, when using for a long time or be subject to extraneous extruding, cable can be made to deform.
Many producers, in order to strengthen the compactness of the construction of cable, all with the addition of the construction of cable such as armour, steel band, and this not only increases the production cost of cable, but also increase weight and the maintenance cost of cable.
General cable does not possess good fillibility, and in construction with when pulling, adjacent core can constantly rub, and destroys the overall structure type of cable core, not only affects the normal work of cable, also destroys overall aesthetic property.
Therefore, how improving the compactness of the construction of cable, is the current technical issues that need to address of those skilled in the art.
Utility model content
The utility model provides a kind of plastic and flexible foam matter filler, for filling the space that adjacent core is formed when being wound around stranding, can strengthen the compactness of the construction of cable, alleviating the weight of cable, save production cost.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of plastic and flexible foam matter filler, comprise the filler body for filling the space that adjacent core is formed when being wound around stranding, described filler body is strip, and the cross section of described filler body is regular polygon or circle.The shape of regular polygon can be decided according to the different size of cable, the extruding of combining core during stranding makes each limit outside this filler body start distortion, make side form a kind of radian, arc limit that is perfect and core is close to mutually, better can fill the space between core; Make the filler smaller volume of distortion when filler body is squeezed, density becomes large, and cable core structure is more compacted.And this filler body possesses certain water absorption, when moisture infiltration is torn in cable somewhere, this filler body can absorb certain moisture, keeps core not to be immersed in water and can normally to work.This filler body also possesses good coloring, and the needs that can have more producer carry out painted to this filler body.
Preferably, described filler body is that flexible polyurethane foams is made.This material water absorption is high, has excellent water preventing ability; Mechanical strength is good, and shock-absorbing capacity is excellent; Processability is good, is easy to molded; The advantages such as coloring is good, and thermal adaptability is strong, and radioresistance is excellent, and dimensional accuracy is high, even structure.
Preferably, the density of described filler body is 35 ~ 45kg/m3.During stranding, filler body is subject to the extruding of core, smaller volume, and density becomes large, and cable core structure is more compacted.
Preferably, described filler body interior is provided with reinforcement.Reinforcement can increase the mechanical performance of cable, also makes core and filler body be not easy to be damaged in cabling process.
Preferably, described reinforcement is metal reinforcement or glass fiber tape.Glass fiber tape adopts high-temperature-resistant high type glass fibre, processes through special process.There is high temperature resistant, insulation, insulation, fire protection flame retarding, corrosion-resistant, ageing-resistant, the feature such as weatherability, high strength, smooth in appearance.Spun-glass insulation heat insulating belt, silicon rubber glass fibre is mainly divided into protect heat insulating belt, glass radiation proof heat-preserving heat-insulating belt etc.
Preferably, the cross section of described reinforcement is regular polygon or circle.The different edge shape of reinforcement can produce different adhesive force between filler body, regular polygon is compared with circle, more be conducive to avoiding relative movement between the two or rotation, but processing cost increases to some extent, can select according to specific needs.
Preferably, described reinforcement has one or more.When filler inside arranges multi reinforcements, the mechanical performance of filler and whole cable all can correspondingly increase, but simultaneously due to reinforcement increase time, the minimizing of this cognitions of filler, thus its elasticity can weaken to a certain extent to some extent, its filling effect and water absorption etc. all can correspondingly weaken.Equally, also can there be certain influence the position that reinforcement is arranged to the filling effect of filler.
Preferably, described reinforcement only has one, and described reinforcement is located at filler body center position, and described reinforcement is arranged on filler body length direction.Such design makes the combination property of filler all ideal, is more preferably scheme.
The utility model discloses a kind of plastic and flexible foam matter filler, for filling the space that adjacent core is formed when being wound around stranding, owing to combining the extruding of core during stranding, there is elastomeric filler and deform, the space between core can be filled better.And being added with fire-proof heat-insulating reinforcement in the middle of filler makes cable have more mechanicalness, cable can be made to remain unchanged when the external world is squeezed shape, make it have higher crushing resistance.And filler water absorption of the present utility model is high, has excellent water preventing ability; Mechanical strength is good, and shock-absorbing capacity is excellent; Processability is good, is easy to molded; Coloring is good, and thermal adaptability is strong, and dimensional accuracy is high, even structure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of a kind of plastic and flexible foam of the utility model matter filler;
Fig. 2 is the structural representation that the utility model fills after adjacent core winding stranding.
Embodiment
As shown in Figure 1, 2, for the preferred embodiment 1 of a kind of plastic and flexible foam of the utility model matter filler, comprise the filler body 1 for filling the space that adjacent core 3 is formed when being wound around stranding, described filler body 1 is strip, and the cross section of described filler body 1 is regular polygon or circle.Can decide to be adopt square, regular pentagon, regular hexagon etc. according to the different size of cable, adopt circle also can realize, the extruding of combining core 3 during stranding makes each limit outside this filler body 1 start distortion, side is made to form a kind of radian, arc limit that is perfect and core 3 is close to mutually, better can fill the space between core 3; When filler body 1 is squeezed, make the filler smaller volume of being out of shape, density becomes large, and cable core 3 structure is more compacted.And this filler body 1 possesses certain water absorption, when moisture infiltration is torn in cable somewhere, this filler body 1 can absorb certain moisture, keeps core 3 not to be immersed in water and can normally to work.This filler body 1 also possesses good coloring, and the needs that can have more producer carry out painted to this filler body 1.
