Abstract

The utility model discloses an island is with anticorrosive dampproofing low pressure power cable, characterized by adopt by the many soft copper wires of tin -plating transposition and compress tightly the conductor of formation, block water the ribbon around the package and become the inlayer lacing that blocks water on the conductor, and the extruded insulation layer constitutes insulation core the inlayer blocks water the lacing outside, by many insulation core transposition strandings and pack that it restricts to block water constitutes the cable core, outside the cable core, set gradually from inside to outside be through the skin that the ribbon that blocks water around the package becomes block water interior sheath that lacing, crowded package formed, indulge package aluminum plastic tape layer to and the anticorrosive waterproof type polyethylene material's of crowded package formation oversheath layer. The utility model discloses the manufacture is convenient, production efficiency is high, with low costs, and compliance, the anticorrosive and dampproofing function of cable are good, can effectively guarantee operation safety, long service life.

Description

Island anticorrosion protection against the tide lv power cable

Technical field

This utility model relates to a kind of power cable, especially island anticorrosion protection against the tide lv power cable.

Background technology

Continually developing and utilizing along with marine resources, the exploitation on island is increasingly subject to country and the attention of society, the coastal people are in order to improve environment simultaneously, improve production, quality of life, the demand of electric power, communication is constantly strengthened, produces long length high pressure island power communication comprehensive cable for developmental research and provide wide market prospect. Ensureing island power supply safety, the reliability of transmission electric power is then imperative. In the cable of island, the demand of lv power cable is relatively larger.

Coastal and island natural environment is different from inland, and it belongs to salt-soda soil, moist big. It is laid in underground, accordingly, it would be desirable to consider the adaptive capacity of the resistance to environment of cable owing to cable is substantially. Prior art does not have special island anticorrosion protection against the tide lv power cable.

Utility model content

This utility model is for avoiding the weak point existing for above-mentioned prior art, offer one manufacture is easy to process, production efficiency is high, cost is low, and cable flexibility is good, anticorrosion and moisture-proof function strong, can ensure that the island anticorrosion protection against the tide lv power cable running safety.

This utility model adopts the following technical scheme that

Being structurally characterized in that of this utility model island anticorrosion protection against the tide lv power cable: adopt and merged, by many tin plating soft copper skein silks, the conductor that compression is formed, on described conductor, wrapped waterstop forms internal layer water blocking tape layer, insulated wire cores is constituted, by many insulated wire cores twisted synthesizing cables and fill waterproofing rope and constitute cable core at the outer extruded insulation layer of described internal layer water blocking tape layer; Outside cable core, what set gradually from inside to outside is that the outer layer water blocking tape layer formed by wrapped waterstop, the sheath extruding formation, vertical alclad are moulded belt, and extruded the external sheath layer of the anticorrosion water proof type polyethylene material of formation.

The construction features of this utility model island anticorrosion protection against the tide lv power cable lies also in:

The compression coefficient of described conductor is not less than 90.

Described insulating barrier is to extrude with crosslinked polyethylene or ethylene-propylene rubber insulated material and formed through sulfuration.

Described sheath is to adopt crowded tube process to extrude formation.

Described external sheath layer is to extrude formation with linear low density polyethylene or medium density polyethylene black material.

Compared with the prior art, this utility model has the beneficial effect that:

1, this utility model considered cable under burn into wet environment institute affected. Conductor have employed the conductor that tinned copper wire impacted process is formed so that it is conductor under burn into wet environment longtime running electric property be not susceptible to change, and it is closely knit to press rear conductor, and steam is difficult to invade, it is ensured that the safety of electrical equipment;

2, the crowded tube process of this utility model Cable Construction Design extrudes sheath, adds the density of cable core, and itself and vertical alclad are moulded belt and jointly served good waterproof effect, and technique is simple.

3, to have employed water resistance at external sheath layer better for this utility model, having again the good polyethylene material of anticorrosion waterproof of certain rotproofness, make cable be in for a long time in salt-soda soil and wet environment and not easily seep water, its material is easy to get, global design is scientific and reasonable, convenient processing and manufacture.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

Number in the figure: 1 conductor, 2 internal layer water blocking tape layers, 3 insulating barriers, 4 waterproofing rope, 5 outer layer water blocking tape layers, 6 sheaths, belt moulded by 7 vertical alclads, 8 external sheath layers.

Detailed description of the invention

Referring to Fig. 1, in the present embodiment, anticorrosion protection against the tide lv power cable in island is to adopt to be merged by many tin plating soft copper skein silks to compress the conductor 1 formed, on conductor 1, wrapped waterstop forms internal layer water blocking tape layer 2, insulated wire cores is constituted, by many insulated wire cores twisted synthesizing cables and fill waterproofing rope 4 and constitute cable core at the outer extruded insulation layer 3 of internal layer water blocking tape layer; Outside cable core, what set gradually from inside to outside is that the outer layer water blocking tape layer 5 formed by wrapped waterstop, the sheath 6 extruding formation, vertical alclad are moulded belt 7, and extruded the external sheath layer 8 of the anticorrosion water proof type polyethylene material of formation.

In being embodied as, the compression coefficient of conductor 1 is not less than 90; Insulating barrier 3 is to extrude with crosslinked polyethylene or ethylene-propylene rubber insulated material and formed through sulfuration; Sheath 6 is to adopt crowded tube process to extrude formation; External sheath layer 8 is to extrude formation with linear low density polyethylene or medium density polyethylene black material.

This utility model, for the natural conditions on island, gives the cable meeting environmental requirement, it is ensured that the operation safety of cable, and can extend its service life, has important economy and social value.
