Abstract

The utility model discloses a movable shielded power cable with tensile conductors, which comprises a plurality of conductors, wherein the conductors are internally provided with tensile steel wires; insulating layers are arranged outside the conductors; a cabling and core wrap layer is arranged outside the insulating layers; the cabling and core wrap layer is externally provided with a shielding layer; and the shielding layer is externally provided with a sheath layer. The shielded power cable is simple in structure and convenient to manufacture; the outside diameter of the cable can be decreased; the space of an electric cabinet can be saved; and the service life of the cable can be prolonged.

Description

A kind of tension conductor moves with the shielding power cable

Technical field

The utility model relates to the tension conductor and moves with shielding power cable field, relates in particular to a kind of tension conductor and moves with the shielding power cable.

Background technology

Along with society constantly advances; The user requires also increasingly high to cable performance, to moving with the requirement of cable too, requirement also is increasingly high; If cable does not have good flexibility and good tensile property, influence the useful life of electric wire so to a great extent.At present domestic suitable mobile a lot of with the insulation and the sheath material of cable; And tensile structure mostly adopts and adds the both sides that place round cable or the both sides of flat cable; It is relatively more difficult when equipment is installed; And tensile structure of this power cable and conductor are together, as long as conductor is connected on the required mobile device.

The utility model adopts conductor and strengthens the stranded together back of tension finer wire wrap insulate; Then stranding, band, braiding, wrap jacket; Through the change of conductor and tension, itself has just become the tension conductor conventional conductor, and the outside diameter of cable has also reduced much simultaneously; The space of simultaneously also having practiced thrift equipment is so the user need not the equipment of changing into the space of the tensile property of cable and regulator cubicle is limited.

The utility model content

In order to overcome above-mentioned defective, the utility model provides a kind of tension conductor to move with the shielding power cable, can reduce the outside diameter of cable, practices thrift the regulator cubicle space, prolongs cable useful life.

The utility model for the technical scheme that solves its technical problem and adopt is: the utility model relates to a kind of tension conductor and moves with the shielding power cable; Comprise many conductors; In conductor, be respectively equipped with the tension steel wire, be provided with insulating barrier, be provided with stranding and core wrap in the insulating barrier outside in the conductor outside; Outside stranding and core wrap, be provided with screen, outside screen, be provided with restrictive coating.

As the further improvement of the utility model, said conductor material adopts the 5th kind of annealed copper conductor or the tin-coated copper that the drawing of standard oxygen-free copper bar forms among the GB/T3956, and the cross section is generally 2.5～240m ㎡.

As the further improvement of the utility model, said screen cable core weaves copper free wire outward, and density is not less than 80%.

As the further improvement of the utility model, said restrictive coating adopts soft polyvinyl chloride.

The beneficial effect of the utility model is: can reduce the outside diameter of cable, practice thrift the regulator cubicle space, prolong cable useful life.

Description of drawings

Fig. 1 is the utility model structural representation;

Indicate among the figure: 1-conductor, 2-tension steel wire, 3-insulating barrier, 4-stranding and core wrap, 5-screen, 6-restrictive coating.

Embodiment

In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection range.

Fig. 1 has shown a kind of tension conductor of the utility model and has moved the execution mode with the shielding power cable: comprise many conductors 1, in conductor 1, be respectively equipped with tension steel wire 2, be provided with insulating barrier 3 in conductor 1 outside; Be provided with stranding and core wrap 4 in insulating barrier 3 outsides, outside stranding and core wrap 4, be provided with screen 5, outside screen 5, be provided with restrictive coating 6; The utility model is simple in structure, and is easy to make, can reduce the outside diameter of cable; Practice thrift the regulator cubicle space, prolong cable useful life.
