Abstract
The utility model discloses an optical-fibre combined cable, comprising a plurality of conductors wrapped with insulating layers, wherein aluminium foil Mylar is covered outside the insulating layers, the plurality of conductors wrapped with the aluminium foil Mylar are twisted by taking an elastic rope as a centre to form a cable core, a lapping layer and an inner sheath layer are sequentially wrapped outside the cable core, optical fibres wrapping the loose sleeve are arranged between the lapping layer and the inner sheath layer, an armour layer is arranged outside the inner sheath layer, and a sheath layer is moulded outside the armour layer via extrusion. The optical-fibre combined cable disclosed by the utility model has a simple structure, realizes a new application of combining optical fibres with a cable, facilitating online monitoring for the power cable, and realizes the anti-extrusion capacity and the shielding performance of the cable during a monitoring use process via associated auxiliary equipment.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of optical fiber combination cable.
Background technology:
Power cable is in operation and all will be defined under certain ambient temperature; Allow the electric current of power cable through limit; Confirm the useful life and the safety of the insulating barrier of power cable, the measurement of power cable conductor working temperature is to infer through the temperature of measuring cable surface, and it is big to measure difficulty for the cable that buries ground; The characteristics of optical fiber transmission signal are that attenuation constant is little; Repeater span is long, utilizes optical fiber to have the characteristics of radiating the transmission principle dorsad to obtain the information such as temperature of optical fiber place space-time to the transmission signals of light, forms online long distance detection.
Original cable was in long distance detection, and anti-extrusion ability and shielding properties are relatively poor, in actual environment for use adaptive capacity relatively a little less than.
The utility model content:
In order to remedy the defective of prior art, the purpose of the utility model provides a kind of optical fiber combination cable, reasonable in design, and the overall performance of cable gets a promotion in actual the use.
The technical scheme of the utility model is following:
The optical fiber combination cable; Comprise the conductor of several wrap insulate layers, it is characterized in that: described insulating barrier is coated with the aluminium foil wheat and draws, and the conductor that described several parcel aluminium foil wheats are drawn is the stranded formation cable core in center with the elastic threads; Cable core is enclosed with lapping layer, inner restrictive coating outward successively; Be provided with the optical fiber of the loose sleeve pipe of parcel between lapping layer and the inner restrictive coating, inner restrictive coating is provided with armour outward, and the outer extrusion moulding of armour has restrictive coating.
Described optical fiber combination cable is characterized in that: the thickness that described aluminium foil wheat is drawn is not less than 0.1mm.
Described optical fiber combination cable is characterized in that: described elastic threads adopts the thermoplastic elastomer (TPE) extrusion moulding to constitute.
The utility model has the advantages that:
The utility model is simple in structure, has realized the new application that optical fiber and cable combine, and makes things convenient for the power cable on-line monitoring, through relevant auxiliary equipment, has realized cable anti-extrusion ability and shielding properties in the monitoring use.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
The optical fiber combination cable comprises the conductor 1 of several wrap insulate layers 2, and insulating barrier 2 is coated with the aluminium foil wheat and draws 3; Improved the shielding properties of cable, anti-external interference performance, it is the stranded formation cable core in center with elastic threads 4 that several parcel aluminium foil wheats are drawn 3 conductor 1; Cable core is enclosed with lapping layer 5, inner restrictive coating 6 outward successively; Lapping layer can adopt high temperature resistant polyurethane film band overlapping wrapped, improves fire resistance, is provided with the optical fiber 8 of the loose sleeve pipe 7 of parcel between lapping layer and 5 inner restrictive coatings 6; Be provided with armour 9 outside the inner restrictive coating 6, armour 9 outer extrusion moulding have restrictive coating 10.
The aluminium foil wheat draws 3 thickness to be not less than 0.1mm.
