Abstract
The utility model relates to a new single-core steel tape armored 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 inner sheath layer. The outside of the inner sheath layer is provided with a steel tape armored layer. The outside of the steel tape armored 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 that the cable can be prevented from being damaged by animals and plants, the wear resistance is enhanced, the insulating reliability is good and the flame retardant effect is good. The cable can be used in situations such as indoors, tunnels and cable trenches where 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 cored steel belt 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 cored steel belt 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 cored steel belt 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 steel-tape armouring outward, and steel-tape armouring 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.
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; Steel-tape armouring 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 etc. can bear mechanical external force.
Description of drawings
