Abstract

The utility model discloses a high-flame retardation frequency conversion tension cable. The cable is composed of power wire cores, insulation wire cores, a nanometer flame retardation insulation layer, a copper covered steel armored layer and a silicone rubber oversheath. The power wire cores are formed by extruding multiple copper core conductors each with a sectional area of 35 mm<2> by a polyethylene insulation layer; the insulation wire cores are formed by extruding multiple copper core conductors each with a sectional area of 10 mm<2> by a fluorubber sheath; a flame retardation wrapping layer presses the three power cable cores tightly; the three insulation wire cores are arranged at the gaps at the outer sides of contact portions of every two power wire cores; the nanometer flame retardation insulation layer, the copper covered steel armored layer and the silicone rubber oversheath wrap the flame retardation wrapping layer from the inside to the outside in an extruded mode; the polyethylene insulation layer and the fluorubber sheath are each internally provided with a drainage wire core; and a tension steel wire is arranged at a space enclosed by the three power wire cores. The cable provided by the utility model has the advantages of stable performance, flame retardation, anti-interference and tensile properties, stable currents, and aging resistance.

Description

A kind of high flame retardant frequency conversion tensile cable

Technical field

The utility model relates to cable, relates in particular to a kind of high flame retardant frequency conversion tensile cable.

Background technology

Along with the develop rapidly of China's industry, plastic insulated cable constantly increases in the industrial scope of application and consumption, common plastics insulated cable anti-flammability at present used is poor, add after fire retardant, electrical insulating property reduces, when burning, produce a large amount of poisonous and harmful smog, environment, equipment and personnel's life is had to very big harm, in use procedure, also will pull and haul a man, signal disturbs large, not ageing-resistant, therefore in work progress because the cable sheath of pulling and hauling a man is very easily impaired, useful life is short, the disturbed severity of signal, and electric current is unstable.

Utility model content

According to above-mentioned situation, the utility model object is to provide a kind of high flame retardant frequency conversion tensile cable.

Scheme of the present utility model is as follows: a kind of high flame retardant frequency conversion tensile cable, it is made up of power core, insulated wire cores, nano flame retardant insulating barrier, copper covered steel armour and silicon rubber oversheath, and described power core is that to extrude many sectional areas by polyethylene layer be that the copper core conductor of 35 square millimeters forms; Described insulated wire cores is that to extrude many sectional areas by fluorubber sheath be that the copper core conductor of 10 square millimeters forms; Fire-retardant lapping layer closely compresses three power cores, and three insulated wire cores are arranged on gap location outside every two power core contact sites; Described nano flame retardant insulating barrier, copper covered steel armour and silicon rubber oversheath are from inside to outside extruded on fire-retardant lapping layer; In described polyethylene layer and fluorubber sheath, be all provided with a drainage core; In the space that described three power cores surround, be provided with a tension steel wire.

The beneficial effects of the utility model: the utility model stable performance, there is fire-retardant, anti-interference and stretch-proof performance, and current stabilization, ageing-resistant.
