Abstract
The utility model discloses a reinforced cable, which comprises a cable core stranded by a plurality of wire cores, wherein each wire core consists of a middle main cable conductor, and a main cable isolating layer and a main cable insulating layer which are arranged outside the main cable conductor in turn; a lapping layer and a sheath are arranged outside the cable core in turn; and a plurality of reinforced steel cores are arranged at a gap of the cable core or outside the cable core. The operating requirement in a special environment is met by improving the tensile strength of the cable.
Description
Technical field
The utility model relates to the power cable field, relates in particular to a kind of cable that is moving under having than big pulling force condition.
Background technology
As everyone knows, conventional cable has played the transmitting effect to electric energy and signal, yet in using electricity system, must have various complex environments and laid condition, for example the vertical cable that uses reaches the cable that need carry big pulling force when the length cable installation in pipe in the high building elevator, particularly control cable and instrument cable etc., the copper conductor maximum pulling force that can carry is 7kg/mm usually
2, the pulling force that the aluminium conductor maximum can be carried is 4kg/mm
2, and be attached to pulling force on the cable under the specific environment often considerably beyond load, at this moment, normal cable just is difficult to be competent at, and is easy to appearance, especially the small dimension cable or the aluminium conductor cable that cause the broken string or the conductor drawing-down is caused operation troubles.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of ruggedized cable that can bear big pulling force is provided.
Ruggedized cable described in the utility model, comprise the cable core that is twisted into by the several wire core, described core is by the leader cable conductor of centre, and leader cable separator that outside the leader cable conductor, sets gradually and leader cable insulating barrier composition, cable core sets gradually lapping layer and sheath outward, in the cable core gap or some reinforcement steel cores are being set outside cable core.
Above-mentioned reinforcement steel core can be by many stranded the forming of finer wire.Can coated insulation protective layer or semiconductive protective layer outside strengthening steel core.
The utility model is when the cable stranding; to strengthen steel core and be placed on the cable core gap; this strengthens steel core can be solid; can be many stranded the forming of finer wire, steel core is outer can coated insulation protective layer or semiconductive protective layer, strengthens steel core and can be placed in the middle of the cable core; also can be placed on edge filling place; if any special requirement, also can be attached to outside the cable core, connect as one with cable core.The diameter of steel core and steel wire radical need to determine or determined by customer requirement according to the concrete environment for use of cable.By strengthening the tensile strength of cable itself, satisfy the requirement of under particular surroundings, using.
The utility model need not purchased any production equipment, does not need existing equipment is transformed yet, be to finish, reduced the production technology difficulty, reduced labour intensity by the packing material place that steel core or steel strand wire is placed on former stranding equipment, save raw material, improved production efficiency.Strengthen the function of use of power cable, solved user's practical difficulty.
Description of drawings
Fig. 1 is first kind of structural representation of the present utility model,
Fig. 2 is second kind of structural representation of the present utility model,
Fig. 3 is the third structural representation of the present utility model.
Embodiment
As shown in Figure 1-Figure 3; ruggedized cable of the present utility model; comprise the cable core that is twisted into by the several wire core; described core is by the leader cable conductor 1 of centre; and leader cable separator 2 that outside the leader cable conductor, sets gradually and leader cable insulating barrier 3 compositions; in the cable core gap or some reinforcement steel cores 5 are being set, strengthen steel core 5 by many stranded the forming of finer wire, its outer insulating protective layer or semiconductive protective layer of coating outside cable core.Strengthen steel core and can be placed on cable core middle (Fig. 3), also can be placed on edge filling place (Fig. 1, Fig. 2).Outside cable core, set gradually lapping layer 4 and sheath 6.
The manufacture method of the utility model power cable, be with strengthening the stranded stranding of steel core extremely with cable, become the traction ruggedized cable of forming by cable, strengthening core, the form of strengthening steel core is placed in employing at former cable filling position, wrapped nonwoven fabrics etc. outside it, and then by extruding restrictive coating, or when extruding oversheath, the reinforcement steel core is attached to outside the cable by extruding, but link into an integrated entity with cable, realize strengthening the good combination between steel core and the cable, realize aforementioned goal of the invention.
Claims (3)
1. ruggedized cable, comprise the cable core that is twisted into by the several wire core, described core is by the leader cable conductor (1) of centre, and leader cable separator (2) that outside the leader cable conductor, sets gradually and leader cable insulating barrier (3) composition, cable core sets gradually lapping layer (4) and sheath (6) outward, it is characterized in that in the cable core gap or some reinforcement steel cores (5) are being set outside cable core.
2. ruggedized cable according to claim 1 is characterized in that described reinforcement steel core (5) is by many stranded the forming of finer wire.
