Abstract
The utility model relates to a novel single-core steel wire armored cable including a metal conductor. The metal conductor is coated with a conductor shielding layer. The conductor shielding layer is coated with an insulating layer. The insulating layer is coated with an insulating shielding layer. The insulating shielding layer is coated with a copper-band shielding layer. An inner sheath layer is arranged outside the copper-band shielding layer. A steel wire armor is arranged outside the inner sheath layer. An outer sheath layer is arranged outside the steel wire armor. The novel single-core steel wire armored cable provided by the utility model is suitable for conditions having rated voltage of 3.6/6 kV to 26/35kV, can prevent from being damaged by animals and plants, and has improved wear-resistance performance, high insulation reliability and good anti-flaming effect. The novel single-core steel wire armored cable is applied to occasions such as the indoor, tunnels, cable groove shafts and the like and can bear a certain volume of mechanical external forces and pulling forces.
Description
Technical field
The utility model relates to the technical field of power cable, especially a kind of novel single core wire armoured 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.
Even if cable has good heat resistance simultaneously, in the higher occasion of fail safe, but can not prevent vegeto-animal destruction, also possibly bring big indirect loss to power supply.
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 wire armoured cable; It can prevent vegeto-animal destruction and strengthen anti-wear performance, and 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 wire armoured cable, comprise a metallic conductor, and metallic conductor is coated with conductor shield; Conductor shield is coated with insulating barrier; Insulating barrier is coated with insulation screen, and insulation screen is coated with the copper strips screen, and the copper strips screen is provided with inner restrictive coating outward; Inner restrictive coating is provided with wire armoring outward, and wire armoring 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 inner restrictive coating.
Further: wire armoring contains copper wire.
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; Wire armoring can prevent vegeto-animal destruction and strengthen anti-wear performance; 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, cable trough vertical shaft etc. can bear mechanical external force and certain pulling 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, 8, inner restrictive coating, 9, wire armoring.
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 wire armoured cable as shown in Figure 1, it comprises a metallic conductor 1, metallic conductor 1 is coated with conductor shield 2; Conductor shield 2 is coated with insulating barrier 3, and insulating barrier 3 is coated with insulation screen 4, and insulation screen 4 is coated with copper strips screen 5; The copper strips screen 5 outer inner restrictive coatings 8 that are provided with; The inner restrictive coating 8 outer wire armorings 9 that are provided with, wire armoring 9 can prevent vegeto-animal destruction and strengthen anti-wear performance, the wire armoring 9 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 inner restrictive coating 8; Wire armoring 9 contains copper wire.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, cable trough vertical shaft etc. can bear mechanical external force and certain pulling 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.
