Abstract

The utility model discloses a composite cable for a smart power grid. The cable comprises a plurality of power core conductors in a bundling and turning joint manner. Each power core conductors is wrapped with an irradiation cross linked polyethylene insulating layer. A radio frequency cable is disposed in the gap of the power insulation cable cores. A filling material is filled in the gap between the power insulation cable cores and the radio frequency cable. Outside the composite line pencil of the power insulation cable cores and the radio frequency cable, a conductor shielding layer, an insulation layer, an insulation shielding layer, a semiconductive strapping tape, a waterproof layer, an anti-corrosion layer and a sheath layer, from inside to outside, are successively disposed. Fiber composite units are composited in the waterproof layer. Each fiber composite unit, from inside to outside, comprises a fiber, a filling cable paste layer and a high strength plastic loose tube. There are at least three fiber composite units symmetrically distributed in the center of the waterproof layer. The beneficial effects are that the cable integrates power energy and signal transmission as a whole, allows electric power, broadcast and TV, telecommunication and network to be used in a unity, and greatly reduces engineering cost. The cable is advantaged by being large in information capacity, small in transmission attenuation, safe and reliable without mutual interference.

Description

A kind of used for intelligent electric network composite cable

Technical field

The utility model relates to a kind of cable, especially a kind of composite cable for intelligent power grid that collects broadcasting and TV, telecommunications, network, electric power four net fusions.

Background technology

It is one of State Grid Corporation of China's development plan that four nets merge, and the sharpest edges of power network are to have covered all users.Only have at present part family to have phone and broadband, but all families all use a little, power line communications all has more multiple access user than other various network accesses.If many net unifications, are mainly to add optical fiber in power distribution network, the cost of optical fiber is very low now, if optical fiber follows cable to walk, realizes four nets and merges, and can reduce factory's cost, economizes on resources, and is conducive to the extensive penetration and promotion of intelligent grid.But also there is no on the market finely to meet at present the cable of this requirement.

Utility model content

The technical problem that the utility model solves is, for the deficiencies in the prior art, provides a kind of used for intelligent electric network composite cable.

The technical scheme that the utility model adopts is: a kind of used for intelligent electric network composite cable, comprise the power line core conductor that some bunchys link, and power line core conductor is coated with IXPE insulating barrier; In space between power insulated wire cores, be provided with radio frequency cable, between power insulated wire cores and radio frequency cable, be filled with inserts; Outside the composite bundle of power line core conductor and radio frequency cable, also be provided with successively from the inner to the outer conductor shield, insulating barrier, insulation screen, semiconductive strapping, water blocking layer, lumarith and restrictive coating, in water blocking layer, be compounded with optical fiber recombiner unit, optical fiber recombiner unit comprises successively from the inner to the outer optical fiber, fills optical fiber cream layer and highstrenghtpiston pine sleeve pipe; Described optical fiber recombiner unit is at least three, and in water blocking layer, Central Symmetry distributes.

The utlity model has following beneficial effect: current collection can be transmitted in one with signal, make electric power, broadcasting and TV, telecommunications, network four nets can unify use, greatly reduce project cost; Have that information capacity is large, transmission attenuation is little, the advantage such as interference-free, safe and reliable each other.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:

Fig. 1 is the structural representation of the utility model composite cable.

Embodiment

As shown in Figure 1, used for intelligent electric network composite cable, comprises the power line core conductor 1 that some bunchys link, and power line core conductor is coated with IXPE insulating barrier 2; In space between power insulated wire cores, be provided with radio frequency cable 3, between power insulated wire cores and radio frequency cable, be filled with inserts 4; Outside the composite bundle of power insulated wire cores and radio frequency cable, also be provided with successively from the inner to the outer conductor shield 5, insulating barrier 6, insulation screen 7, semiconductive strapping 8, water blocking layer 9, lumarith 10 and restrictive coating 11, in water blocking layer, be compounded with optical fiber recombiner unit, optical fiber recombiner unit comprises successively from the inner to the outer optical fiber 12, fills optical fiber cream layer 13 and highstrenghtpiston pine sleeve pipe 14; Described optical fiber meets unit and has three, and in water blocking layer, Central Symmetry distributes.

To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection range of the utility model claim.
