Abstract
The utility model discloses a cable with a steel pipe outer sheath. The cable comprises an insulation cable core located in the center. An inner steel wire layer, a middle steel wire layer and an outer steel wire layer are sequentially arranged on the outer part of the insulation cable core. A steel pipe is arranged on the outer part of the outer steel wire layer. By adopting the steel pipe as the outer sheath, the cable with the steel pipe outer sheath solves the problem that conventional steel wire armor is not resistant to wearing. The service lifetime of the cable is prolonged. Meanwhile, the steel wires inside the steel pipe are divided into four layers. The cable with the steel pipe outer sheath is thus especially suitably used in occasions with large-power requirements.
Description
Technical field
The utility model relates to a kind of cable with steel pipe outer jacket, belongs to field of mechanical technique.
Background technology
Traditional cable in use, because the base attribute of armouring wire is cylindrical, is point in borehole wall wearing and tearing and the wearing and tearing of line, namely and the life-span of cable sharply shortens.And the intensity of armouring wire and antiseptic power are relatively poor or steel wire in the middle of have the reason such as joint also easily to cause outer armour fracture of wire; Insulating material quality problems or heat resistance are relatively poor, cause insulating barrier aging very fast, and the cable core insulating capacity descends; Even if existing cable has strong integument, the steel wire number of plies in general cable is less, and not only power is less, and the tension of cable, shearing strength are also inadequate.
The utility model content
The utility model provides a kind of cable with steel pipe outer jacket, can overcome above defective, and cable has the water pipe precaution layer, and the steel wire floor in cable also has increase simultaneously, and the life-span of cable is obviously improved.
For solving above technical problem, the utility model provides following technical scheme: a kind of cable with steel pipe outer jacket, described cable comprises the insulation cable core that is positioned at the center, and insulation cable core outside is provided with steel wire of internal layer, middle level steel wire and cover wire, and the cover wire outside is provided with steel pipe.
Further, described insulation cable core comprises conduction cable core and insulating barrier, and the conduction cable core is copper wire.
Further, the material of described insulating barrier is polypropylene pp.
This cable with steel pipe outer jacket that the utility model relates to, outer jacket is steel pipe, has changed tradition with the not anti abrasive way of wire armoring, has carried the useful life of high cable; Simultaneously, the steel wire in steel pipe is total up to four layers, and is particularly applicable for requiring powerful occasion.
Description of drawings
Fig. 1 is a kind of construction of cable schematic diagram with steel pipe outer jacket of the utility model.
Embodiment
As shown in Figure 1, cable comprises the insulation cable core 5 that is positioned at the center, and insulation cable core 5 outsides are provided with steel wire of internal layer 4, middle level steel wire 3 and cover wire 2, and cover wire 2 outsides are provided with steel pipe 1.
Insulation cable core 5 comprises conduction cable core and insulating barrier, and the conduction cable core is copper wire.
The material of insulating barrier is polypropylene pp.
Embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection range of the present utility model.
Claims (3)
1. the cable with steel pipe outer jacket, is characterized in that, described cable comprises the insulation cable core that is positioned at the center, and insulation cable core outside is provided with steel wire of internal layer, middle level steel wire and cover wire, and the cover wire outside is provided with steel pipe.
2. a kind of cable with steel pipe outer jacket according to claim 1, is characterized in that, described insulation cable core comprises conduction cable core and insulating barrier, and the conduction cable core is copper wire.
