Abstract
The utility model relates to a polyvinyl chloride insulating polyvinyl chloride sheath fireproof power cable, comprising at least one metal conductor, wherein each metal conductor is wrapped by a fireproof layer, outside the fireproof layer there is provided a polyvinyl chloride insulating layer, outside the polyvinyl chloride insulating layer there is provided a polyvinyl chloride outer sheath layer, and between the polyvinyl chloride insulating layer and the polyvinyl chloride outer sheath layer there is provided a wrapping tape layer. The polyvinyl chloride insulating polyvinyl chloride sheath fireproof power cable is good in fireproof effect, insulating reliability and flame retardation effect, and can be used for places indoors, in tunnels, or in cable trenches, etc., with no machinery outer force exerted thereon.
Description
Technical field
The utility model relates to the technical field of power cable, especially a kind of polyvinyl chloride insulation pvc sheath fireproof power 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, so the fire-retardant problem of the lsafety level of electric wiring and cable more and more causes people's attention.
The fire resistance of simultaneously present cable is relatively poor; In case breaking out of fire, cable fire can produce a large amount of dense smokes, makes rescue work be difficult to carry out; The hydracid corrosive gas that discharges during the substance combustion of Halogen also can shine into certain infringement equipment except harmful to human.
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 polyvinyl chloride insulation pvc sheath fireproof power cable, it fire-resistant effective, and insulating reliability is big, good flame retardation effect.
The utility model solves the technical scheme that its technical problem adopted: a kind of polyvinyl chloride insulation pvc sheath fireproof power cable; Comprise at least one metallic conductor; Each metallic conductor is coated with flame retardant coating; Flame retardant coating is provided with the polyvinyl chloride insulation layer outward, and the polyvinyl chloride insulation layer is provided with the polyvinyl chloride external sheath layer outward, is provided with belting layer between polyvinyl chloride insulation layer and the polyvinyl chloride external sheath layer.
Further: the cross section of each metallic conductor is circular.
Further: each metallic conductor is copper core or aluminium core.
Further: metallic conductor is 2 or 3 or 4.
Further: be provided with packed layer between polyvinyl chloride insulation layer and the belting layer.
Further: metallic conductor is 5.
Further: be equipped with packed layer between the polyvinyl chloride insulation layer outside belting layer and each metallic conductor and between the polyvinyl chloride insulation layer outside each metallic conductor.
The beneficial effect of the utility model: each metallic conductor is coated with flame retardant coating in the cable of the utility model; Make the fire-resistant effect of cable improve, flame retardant coating can effectively prevent hydracid corrosive gas harmful to human and the equipment that cable discharges when the breaking out of fire after-combustion produces the substance combustion of a large amount of dense smokes and Halogen; Flame retardant coating is provided with the polyvinyl chloride insulation layer outward, and under rated voltage 0.6/1kV condition of power supply, the insulating reliability of polyvinyl chloride insulation layer is big; The good flame retardation effect of the polyvinyl chloride external sheath layer that the polyvinyl chloride insulation layer is provided with outward, and then prolonged useful life of cable, the place that this cable is used for is indoor, tunnel and cable trough etc. do not bear mechanical external force.
