Abstract

The invention relates to a special-grade fireproof highly-anti-flaming nanometer power cable which comprises a plurality of cable cores and an outer sheath. Each cable core is formed by a copper conductor, double-layer fireproof mica tape and a fireproof nanometer insulating layer, wherein the double-layer fireproof mica tape and the fireproof nanometer insulating layer are sequentially wrapped outside the copper conductor, anti-flaming filling ropes are filled outside the cable cores, glass fiber tape is wrapped, and the fireproof nanometer outer sheath is wrapped outside the glass fiber tape. The electric-conducting and anti-flaming capabilities of the cable are improved. The cable overcomes the shortcomings existing in a traditional cable, has excellent anti-flaming performance, and has simultaneously the advantages of being high in transmitting rate, small in line loss, high in safety performance in use, free of environmental pollution and low in installing and maintenance cost and the like. The special-grade fireproof highly-anti-flaming nanometer power cable is increasingly applied to various fields and occasions such as subways, nuclear power stations, markets, hospitals and intelligent buildings where the requirements for safety reliability of electrical equipment are high, and has good market prospects.

Description

The superfine fire prevention of a kind of nanometer high flame retardant power cable
Technical field
The present invention relates to a kind of power cable technology, relate in particular to a kind of nanometer stunt fire prevention high flame retardant power cable.
Background technology
Develop rapidly along with China's industry; The scope of application and the consumption of plastic insulated cable in industry constantly increases; Common plastics insulated cable anti-flammability is relatively poor, and behind the adding fire retardant, electrical insulating property reduces; Produce a large amount of poisonous and harmful smog during burning, environment, equipment and personnel's life is all had very big harm.And the nanometer fireproof material can 2.5 times of excess load under rated voltage and is played insulating effect as usual; The long-term work temperature range is :-40 ℃ to 1200 ℃, and insulation as usual; Ablate down at 800-1200 ℃ of naked light, not short circuit in 1.5 hours, it is fiery not cause electricity; Have low cigarette, nontoxic, Halogen, fire-retardant characteristic; Cost is low, good performance indexes; Be suitable for the insulating barrier of various electric wires.In view of the foregoing, for adapting to the demand of future market, I am the positive tissue departmental staff of Development Office of company; Study, confirmed the superfine fire prevention of a kind of nanometer high flame retardant power cable at last, the appearance of this type of cable; Require the occasion of extra-high-speed for those are fire-retardant, guarantee is provided.
Summary of the invention
The present invention is in order to overcome the above problems the superfine fire prevention of the nanometer high flame retardant power cable that a kind of high flame retardant, high conductivity, environmental protection are provided.
Technical scheme of the present invention is: comprise some cores and oversheath; Said core is made up of copper conductor, copper conductor wrapped successively outward double-deck fire-resistant isinglass belt and nanometer fireproof insulating barrier; Said core is filled with fire-retardant gasket for packing outward; And wrapped with glass fiber tape, the nanometer fireproof oversheath is extruded in outside the glass fiber tape.
The invention has the beneficial effects as follows, adopt the high purity oxygen free copper silk, reduced current loss effectively; The double-deck fire-resistant isinglass belt of the vertical outward bag of conductor, mica tape has favorable mechanical and heat resistance, in 550-800 ℃, can use for a long time; Insulating barrier adopts nanometer fireproof high flame retardant material; Adopt during stranding high flame retardant fill and glass fiber tape wrapped, characteristics such as that glass fiber tape has is high temperature resistant, insulation, insulation, fire protection flame retarding, corrosion-resistant, ageing-resistant, weatherability, high strength, smooth in appearance; Outer jacket adopts nanometer fireproof high flame retardant material.The present invention has low cigarette, nontoxic, Halogen, fire-retardant, explosion-proof characteristic, and the characteristics of Nai Neire, anti-naked light, anti-extreme climate environment, environmental protection are a kind of desirable high flame retardant fireproof cables.
The present invention has improved the conduction of cable and fire-retardant ability.This type of cable overcomes the deficiency that traditional cable exists, and has excellent flame-retardant, and with having the transfer rate height, line loss is little again; Usage safety performance is high, non-environmental-pollution; Characteristics are installed, maintenance cost is low etc., increasing each field that is applied in, there are fine market prospects in the place as the security reliability of electric equipments such as subway, nuclear power station, market, hospital, intelligent building is had relatively high expectations.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 is conductor among the figure, the 2nd, and mica tape, the 3rd, insulating barrier, the 4th, fire-retardant gasket for packing, the 5th, glass fiber tape, the 6th, oversheath.
Embodiment
The superfine fire prevention of a kind of nanometer high flame retardant power cable; Comprise some cores and oversheath 6; Said core is made up of copper conductor 1, copper conductor 1 outer wrapped successively double-deck fire-resistant isinglass belt 2 and nanometer fireproof insulating barrier 3; Said core is filled with fire-retardant gasket for packing 4 outward, and wrapped with glass fiber tape 5, and nanometer fireproof oversheath 6 is extruded in outside the glass fiber tape 5.
