Description

The polyvinyl chloride insulation power cable

Technical field

The utility model relates to the technical field of power cable, especially a kind of polyvinyl chloride insulation 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 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 polyvinyl chloride insulation power 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 polyvinyl chloride insulation power cable; Comprise at least one metallic conductor; Each metallic conductor is coated with the polyvinyl chloride insulation layer; The polyvinyl chloride insulation layer is coated with external sheath layer, is provided with belting layer between polyvinyl chloride insulation layer and the external sheath layer.

Further: the cross section of each metallic conductor is circle or fan-like pattern.

Further: each metallic conductor is copper core or aluminium core.

Further: metallic conductor is 2 or 3 or 4 or 5.

Further: be equipped with packed layer between the outer polyvinyl chloride insulation layer that coats of belting layer and each metallic conductor and between the outer polyvinyl chloride insulation layer that coats of each metallic conductor.

The beneficial effect of the utility model: each metallic conductor is coated with the polyvinyl chloride insulation layer in the cable of the utility model, and under rated voltage 0.6/1kV condition of power supply, the insulating reliability of polyvinyl chloride insulation layer is big; The polyvinyl chloride insulation layer is coated with external sheath layer, and the good flame retardation effect of external sheath layer, and then prolonged useful life of cable is used for places such as indoor, tunnel and cable trough.
