Description
Technical Field
The utility model belongs to the technical field of communication and specifically relates to an optical cable at bottom of sea specifically is an optical cable at bottom of having two armoring of relay that contains monitoring electric wire.
Background
With the strong promotion of the strong national strategy of ocean, the submarine optical cable is more and more widely applied to information transmission of various islands, coasts and observation networks. In order to better construct an undersea network system, currently, a common relay double-armor undersea optical cable technology is that a cable core contains a copper conductor and an outer armor double-layer galvanized steel wire. The copper conductor in the cable core is used for high-voltage direct-current power supply transmission, and the copper conductor is not used for detection, so that the monitoring means of the submarine cable is limited.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a two armour submarine optical cables of relay that contain monitoring electric wire, its structure includes cable core and outer armour protective layer, and the cable core is the compound unit of photoelectricity, and the copper pipe of the compound unit of photoelectricity sets up the one deck bonding material outward, and outer armour protective layer includes the electric wire of monitoring usefulness.
Further, the photoelectric composite unit comprises a stainless steel optical unit, an inner armor steel wire, a water-blocking composite, a copper pipe and an insulating sheath which are sequentially arranged from inside to outside; the stainless steel optical unit is a stainless steel pipe containing optical fibers and water-blocking fiber paste, the maximum number of cores is 96, the inner armor steel wire is a phosphatized steel wire or a galvanized steel wire, and the copper pipe is a seamless welded copper pipe.
Further, the outer armor layer is a double-layer galvanized steel wire, wherein the inner layer contains one or more electric wires for monitoring.
Furthermore, asphalt is filled in gaps between the double-layer galvanized steel wires, and polypropylene ropes are wound outside the double-layer galvanized steel wires.
The utility model discloses optical cable simple structure, production is convenient. The submarine cable has the advantages that the submarine cable can be supplied with power by the aid of a conductor and comprises a wire for monitoring, whether the cable is damaged or not is judged by monitoring changes of insulation resistance of the wire, in addition, audio signals can be transmitted through the wire, the position of the cable is measured, whether the cable is in the original construction position or not is judged, and monitoring means of the submarine cable are widened.

In the figure, 1 is a stainless steel light unit, 2 is an inner armor steel wire, 3 is a water-blocking material, 4 is a copper pipe, 5 is an insulating sheath, 6 is an electric wire, 7 is a galvanized steel wire I, 8 is a galvanized steel wire II, 9 is asphalt, and 10 is a polypropylene rope.
Detailed Description
The technical solutions of the present invention are further described below with reference to the drawings and the specific embodiments, but the scope of the present invention is not limited thereto.
As shown in figure 1, the submarine optical cable with the relay double armor and the monitoring wire comprises a cable core and an outer armor protective layer. The cable core is a photoelectric composite unit, and the outer armor protective layer comprises a galvanized steel wire, a monitoring electric wire 6 and a polypropylene rope 10. The insulation layer of the monitoring wire 6 has good seawater corrosion resistance. The photoelectric composite unit is used for transmitting optical signals and electric energy; the photoelectric composite unit includes: stainless steel light unit 1, stainless steel light unit 1 is outer to be twisted one deck interior armour steel wire 2, and interior armour steel wire 2 is packed water blocking material 3 between, and interior armour steel wire 2 is outer to indulge to wrap up welding one deck copper pipe 4, and copper pipe 4 extrudees insulating sheath 5 outward. A layer of bonding material is arranged outside the copper pipe 4 of the photoelectric composite unit, so that the bonding force between the insulating sheath 5 and the photoelectric composite unit is ensured. The outer armor protection is that the galvanized steel wire I7 and the monitoring wire 6 of the first layer of outer armor are twisted outside the insulating sheath 5, then the galvanized steel wire II 8 of the second layer of outer armor is twisted, and the galvanized steel wire for armor has good seawater corrosion resistance. Asphalt 9 is filled between the two layers of galvanized steel wires, and finally a polypropylene rope 10 is wound and twisted.
