Abstract
The utility model discloses an extrusion resistant type composite cable which comprises an optical fiber, a plurality of alloy conductors which are wrapped by insulation layers. The optical fiber is externally provided with a loose tube and an elastic layer which is formed by a thermoplastic elastomer through extrusion molding. The plurality of insulated alloy conductors are twisted with the optical fiber which is wrapped by the elastic layer as a center to form a cable core which is wrapped by a fiberglass cloth thickening layer and a fireproof layer. The fireproof layer is adhered together by using a double-layer polyester tape and then is subjected to overlap wrapping, the thickness of the fireproof layer is not less than 2.5 mm, and the fireproof layer is externally provided with a foaming layer which is wrapped by a shielding layer and a sheath layer. The extrusion resistant type composite cable is simple in structure, online monitoring of the cable is facilitated, the optical fiber is designed at the center of the cable core, combined with the cushioning of the elastic layer, the fiberglass cloth thickening layer and the foaming layer, the optical fiber is effectively protected from being damaged, at the same time, overall performance of the cable are raised, and the extrusion resistant type composite cable is a new application with the combination of the optical fiber and the cable.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of anti-extrusion type composite cable.
Background technology:
Power cable is in operation and all will be defined under certain ambient temperature, allow power cable by the electric current of limit, determine useful life and the safety of the insulating barrier of power cable, the measurement of power cable conductor working temperature is to infer by the temperature of measuring cable surface, it is large to measure difficulty for buried cable, the characteristics of optical fiber transmission signal are that attenuation constant is little, repeater span is long, utilize optical fiber that the signal transmission of light is had the information such as temperature that the characteristics that transmit principle are obtained optical fiber place space-time of radiating dorsad, form online long distance detection.
Original cable is in long distance detection, and anti-extrusion ability, fire resistance, shielding properties are relatively poor, in practical service environment adaptive capacity relatively a little less than so that the shortening in useful life.
The utility model content:
In order to remedy the defective of prior art, the purpose of this utility model provides a kind of anti-extrusion type composite cable, and reasonable in design has prolonged useful life of cable.
The technical solution of the utility model is as follows:
Anti-extrusion type composite cable, it is characterized in that: the alloy conductor that comprises optical fiber, several wrap insulate layers, described optical fiber is provided with loose sleeve pipe outward successively, the thermoplastic elastomer (TPE) extrusion moulding consists of elastic layer, the alloy conductor of several insulation is stranded formation cable core centered by the optical fiber of parcel elastic layer, cable core is coated with glass-fiber-fabric thickening layer, fireprotection layer, described fireprotection layer adopts the double-layer polyester band to adhere to each other rear overlapping wrapped, the thickness of fireprotection layer is not less than 2.5mm, fireprotection layer is provided with foaming layer outward, and foaming layer is wrapped with screen, restrictive coating.
Described anti-extrusion type composite cable is characterized in that: described screen adopts the tinned copper wire braiding to consist of, and the braiding rate is not less than 90%.
The utility model has the advantages that:
The utility model is simple in structure; make things convenient for the power cable on-line monitoring; optical fiber is designed at the cable core center and cooperates the buffering of elastic layer, glass-fiber-fabric thickening layer and foaming layer; effectively protected optical fiber injury-free; simultaneously the overall performance of cable gets a promotion, and is a kind of optical fiber and cable new application that combine.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
