Abstract
The utility model relates to a new single-core cable, comprising a metal conductor. The outside of the metal conductor is wrapped with a conductor shielding layer. The outside of the conductor shielding layer is wrapped with an insulation layer. The outside of the insulation layer is wrapped with an insulation shielding layer. The outside of the insulation shielding layer is wrapped with a copper tape shielding layer. The outside of the copper tape shielding layer is provided with an outer sheath layer. The cable is applied in situations with a rated voltage of 3.6/6kV to 26/35kV. The cable has the advantages of good insulating reliability and good flame retardant effect. The cable can be used in situations such as indoors, tunnels and cable trenches where no external mechanical force can be borne.
Description
Technical field
The utility model relates to the technical field of power cable, especially a kind of novel single-core cable.
Background technology
The current capacity of cable is relevant with the sectional area of conductor thread core usually; Conductor temperature is raise; The temperature of the outer insulating barrier that coats of conductor surpasses the last change that can cause on the insulating barrier generation performance in limited time; Thereby the insulating reliability of insulating barrier is reduced greatly, influence the useful life of cable.
Existing common cable exists structural stability difference and incendive problem simultaneously, so the fire-retardant problem of the lsafety level of electric wiring and cable more and more causes people's attention.
The utility model content
The technical problem that the utility model will solve is: in order to solve the problem that proposes in the above-mentioned background technology, the utility model provides a kind of novel single-core cable, and its insulating reliability is big, good flame retardation effect.
The utility model solves the technical scheme that its technical problem adopted: a kind of novel single-core cable; Comprise a metallic conductor; Metallic conductor is coated with conductor shield, and conductor shield is coated with insulating barrier, and insulating barrier is coated with insulation screen; Insulation screen is coated with the copper strips screen, and the copper strips screen is provided with external sheath layer outward.
Further: the cross section of metallic conductor is circular.
Further: metallic conductor is copper core or aluminium core.
Further: the material of insulating barrier is a crosslinked polyethylene.
Further: the material of external sheath layer is polyvinyl chloride or polyethylene.
Further: be provided with nonwoven layer between copper strips screen and the external sheath layer.
The beneficial effect of the utility model: the cable of the utility model is applicable to that rated voltage is the situation of 3.6/6kV～26/35kV; The insulating reliability of crosslinked polyetylene insulated layer is big; The good flame retardation effect of polyvinyl chloride or polyethylene external sheath layer is used for the place that indoor, tunnel and cable trough etc. can not bear mechanical external force.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the cross section structure sketch map of the utility model.
Among the figure 1, metallic conductor, 2, conductor shield, 3, insulating barrier, 4, insulation screen, 5, the copper strips screen, 6, nonwoven layer, 7, external sheath layer.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Novel single-core cable as shown in Figure 1; It comprises a metallic conductor 1; Metallic conductor 1 is coated with conductor shield 2, and conductor shield 2 is coated with insulating barrier 3, and insulating barrier 3 is coated with insulation screen 4; Insulation screen 4 is coated with copper strips screen 5, the copper strips screen 5 outer external sheath layers 7 that are provided with.
The cross section of above-mentioned metallic conductor 1 is circular; Metallic conductor 1 is copper core or aluminium core; The material of insulating barrier 3 is a crosslinked polyethylene, and insulating reliability is big; The material of external sheath layer 7 is polyvinyl chloride or polyethylene, good flame retardation effect; Be provided with nonwoven layer 6 between copper strips screen 5 and the external sheath layer 7.This cable is applicable to that rated voltage is the situation of 3.6/6kV～26/35kV, is used for the place that indoor, tunnel and cable trough etc. can not bear mechanical external force.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
