Abstract
The utility model provides a drag and make cable, it includes that the tensile is central, the tensile center outside is equipped with several cells spare, the outside of unit spare is equipped with first shielding layer and low smoke and zero halogen outer jacket from inside to outside in proper order, it has the protection filling layer all to fill between unit spare and the tensile center and between unit spare and the shielding layer, wherein, unit spare is strengthened the conductor by the fibre around covering, secondary shielding layer, protection filling layer and a plurality of gangs of intertwine and is formed, around the covering cladding in the secondary shielding layer outside, the protection filling layer is filled in the space around between covering and the fibre enhancement conductor. Compared with the prior art, the utility model discloses following beneficial effect has: 1. Insulation core adopt the fibre to strengthen the flexible conductor structure, has increased the flexibility ability of conductor. 2. Double -shielded the layer has good anti -electromagnetic interference performance.
Description
Technical field
The utility model relates to one and drags and make cable, belongs to field of cable technology.
Background technology
The outdoor use driving of current each industrial and mining enterprises and dragging of crane make cable, adopt Halogen material as butyronitrile composite PVC, neoprene etc., both can produce a large amount of dense smoke and owing to not only having harm to make people suffocate to human body containing its gas discharged of halogen, and also can cause consequential damages to operational outfit during the electric wire burning of these combinations of materials.Along with the environmental protection of applying unit and the raising of awareness of safety, use integral device is comprised and drags the low-smoke non-halogen flame-retardant making cable to propose requirement.
Drag make cable in use constantly bend tension move; this just requires that the construction of cable is closely soft; shore hardness of materials used is little; because cable uses out of doors; require that sheath has excellent cracking resistance, weather resistance; so insulating barrier, protective layer, outer jacket low smoke and zero halogen material are by changing the molecular structure of material after cross-linking radiation, improving cracking resistance, the weather resistance of material, also will overcome the too hard shortcoming of cross-linking low-smoke halogen-free material and keeping soft.By two proof copper-wire braided screen, cable is made to have good interference free performance.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide one and drags and make cable.
The utility model is achieved through the following technical solutions:
One is dragged and is made cable, it comprises tension center, be provided with some root unit parts with being wound around mutually outside described tension center, all described unary outsides are provided with the first screen and low smoke and zero halogen outer jacket from inside to outside successively, are all filled with outer protection packed layer between unit piece and tension center and between unit piece and the first screen; Wherein, described unit piece is strengthened conductor by lapping layer, secondary shielding layer, interior protection packed layer and two strands of fibers with insulating barrier be mutually wound around and is formed; lapping layer is coated on outside secondary shielding layer, and interior protection packed layer is filled in lapping layer and fiber is strengthened in the space between conductor.
Preferably, described unary quantity is 4 ~ 8 strands.
Preferably, the quantity of conductor strengthened by described fiber is 2 ~ 6 strands.
Preferably, described first screen and secondary shielding layer are proof copper-wire braided screen, and described insulating barrier, interior protection packed layer, outer protection packed layer, outer jacket are irradiation crosslinking type low-smoke halogen-free material.
Compared with prior art, the utility model has following beneficial effect:
1. insulated wire cores adopts fiber to strengthen flexible conductor structure, adds the resist bending performance of conductor.
2. cable is soft, and bending radius is little, meets low smoke and zero halogen requirement.
3. double shield layer has good electromagnetism interference.
Accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present utility model will become more obvious:
Fig. 1 is the cross sectional representation of cable of the present utility model;
In figure: 1, conductor strengthened by fiber; 2, low smoke and zero halogen insulating barrier; 3, interior protection packed layer; 4, secondary shielding layer; 5, lapping layer; 6, tension center; 7, outer protection packed layer; 8, the first screen; 9, low smoke and zero halogen outer jacket.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection range of the present utility model.
A kind of drag make cable cross section as shown in Figure 1, it comprises tension center 6, be provided with four root unit parts with being wound around mutually outside tension center 6, all unary outsides are provided with the first screen 8 and cigarette Halogen outer jacket 9 from inside to outside successively, are all filled with outer protection packed layer 7 between unit piece and tension center 6 and between unit piece and the first screen 8; Wherein, unit piece is strengthened conductor 1 by lapping layer 5, secondary shielding layer 4, interior protection packed layer 3 and two strands of fibers with low smoke and zero halogen insulating barrier 2 be mutually wound around and is formed; lapping layer 5 is coated on fiber and strengthens outside conductor 1, and interior protection packed layer 3 is filled in lapping layer 5 and fiber is strengthened in the space between conductor 1.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
