Abstract
The invention relates to a mineral insulated fireproof carbon fiber cable which comprises a carbon fiber composite core, an insulating layer and a metal sheath. The carbon fiber composite core is arranged in the center of the cable; the metal sheath is arranged outside the carbon fiber composite core; and the insulating layer fills between the carbon fiber composite core and the metal sheath. The insulating layer adopts non-combustible high-temperature-resistant magnesium oxide as insulation material. The mineral insulated fireproof carbon fiber cable further comprises a stainless steel optical unit. The carbon fiber composite core comprises carbon fiber filaments and glass fiber filaments, and is formed by stranding the stranded carbon fiber filaments and the glass fiber filaments, then, carrying out resin impregnation on the stranded filaments, and next, carrying out solidification by utilizing a drying oven. The beneficial effects of the mineral insulated fireproof carbon fiber cable are that: the magnesium oxide mineral is utilized as the insulation material, so that the cable is high in insulation and fireproofing performance; the cable not only can be conductive, but also can realize optical fiber communications; and compared with a conventional carbon fiber cable, the mineral insulated fireproof carbon fiber cable is better in flexibility, and has smaller bending radius.
Description
Technical field
The present invention relates to electric wire field, relate in particular to a kind of mineral-insulated fireproof carbon fiber cable.
Background technology
Along with the development of China's economic construction, the continuous growth of electricity needs, cable is also increasing as the demand of the carrier of delivery of electrical energy.But existing cable, such as conventional organic cable (plastic cable), there is defect in its insulation property, such as the easily defect such as aging, non-refractory of plastic insulating layer; Conventional steel reinforced aluminium conductor, its electric property, wire performance are bad.
Mostly the cable conductor of current domestic use is steel reinforced aluminium conductor and aluminium alloy conductors steel, the weight of these wires is larger, resistance is larger, thereby cause transmission of electricity expense high, and operating temperature is lower, can not adapts to the operation under hot conditions, therefore electric power transfer becomes electric power industry development " bottleneck ", various countries are all at research novel overhead power transmission road wire, and to replace traditional steel reinforced aluminium conductor, conventional have a carbon fiber complex core cable.But not enough, soft not enough, bending radius is large for existing carbon fiber complex core intensity, the cable bend performance of making is bad.
In addition, existing cable can not be realized communication function, also needs separately to establish a communication line and could meet communication function, causes and repeats wiring.
Summary of the invention
Technical problem to be solved by this invention is the above-mentioned defect that overcomes cable in prior art, and a kind of mineral-insulated fireproof carbon fiber cable is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of mineral-insulated fireproof carbon fiber cable, is characterized in that, comprises carbon fiber complex core, insulating barrier and metallic sheath; Described carbon fiber complex core is positioned at cable central authorities, and described metallic sheath is positioned at outside described carbon fiber complex core, fills described insulating barrier between described carbon fiber complex core and metallic sheath, and described insulating barrier employing is not burnt, resistant to elevated temperatures magnesium oxide is made insulation material; Also include stainless steel light unit, described stainless steel light unit is contained in described insulating barrier; Described stainless steel light unit forms for being placed in a stainless steel protection pipe by some optical fiber, and stainless steel protection pipe adopts loose tube structure, fills continuously water-blocking material, stainless steel protection pipe outer cladding layer of copper layer in stainless steel protection pipe space; Described carbon fiber complex core comprises carbon fiber wire and glass fiber, by by become strand carbon fiber wire and glass fiber stranded after, adopt resin-dipping, then adopt curing oven to form.
Further, described metallic sheath is seamless copper pipe.
Further, at described metallic sheath, oversheath is set outward, described oversheath is plastic protective layer.
The invention has the beneficial effects as follows: employing is not burnt, the magnesium oxide of high temperature resistant (2800 DEG C) is made insulation material, and it insulate, fire protecting performance will be higher than common rubber or plastic insulating layer; At ragged edge oversheath, i.e. plastics outer jacket, has good Anticorrosive Character; Adopt seamless copper pipe to make metallic sheath, have good bendability; Not only can conduct electricity, can also realize optical fiber communication; Adopt glass fibre and carbon fiber composite structure, through resin-dipping and adopt after curing oven, quality softness, intensity is larger, and the cable of making is better than traditional carbon fibres cable flexibility, has less bending radius, can better serve transmission line.
