Abstract
The utility model relates to a novel water proof cable for seas, in particular to a special environment-friendly compound floating cable for rivers and seas. The cable comprises a sheath consisting of two units; one unit is two pairs of adherent six kinds of shielded twisted pairs, insulation layers are coated outside the two twisted pairs, water-resisting objects are filled in the gap between the two twisted pairs so as to shield signals, and an environment-friendly foam material sheath is extruded outside a water-resisting belt which is coated on a signal shielding layer; the other unit is a 450/750V electric control cable taking halogen-free high-density insulating copper conducting wires as conductors, and a foaming halogen-free environment-friendly material sheath is extruded outside an electric control shielding layer which is coated outside the conductors; and the two units form a circle, a plurality of high-intensity water-resisting fibers and water-resisting objects are added between the two units, and a double-layered halogen-free environment-friendly high-density foaming cover layer sheath is extruded outside the two units at length. The waterproof cable has the advantages of reduced density and uniform stress, can avoid pollution because the raw material in long-time soaking in seas and rivers is decomposed, and has favorable flexibleness and a simple structure, is convenient to process and manufacture, and solves the problem of withdrawing and releasing.
Description
Technical field
The utility model relates to a kind of novel sea and uses water-proof cable, particularly relates to the compound buoyant cable of a kind of Haihe River special environment protection.
Background technology
Cable is when becoming wet, and its insulating properties can change, and causes electric property to be affected, and then causes the electric power shipping accident, causes serious harm for the country and people's property.Especially cable soaks in seawater, and its anti-aggressivity and block-water performance require very strict.Wrapped waterstop present most cable manufacturer is chosen in stranding when producing water-proof cable after, and then fill the filler that blocks water, perhaps select anti-water fat cable insulating material for use.Though the cable of producing like this has certain water preventing ability; But effect is undesirable; Because the above-mentioned measure of blocking water is to getting into the waterproof measure that the inner moisture of cable is taked; Therefore need develop a kind of moisture that can prevent now and get into cable inside, and cable density is little, signal transmits and the environment-friendly cable of electrical control two-way function effect.
Summary of the invention
The utility model purpose provides the operation of a kind of Haihe River and uses the environment-friendly composite buoyant cable, is applicable to that the electric equipment in the operation is installed and the signal transmission such as sea (river) end exploration, ocean (river) rescue, salvaging, scientific investigation.
The technical scheme of the utility model is: special environment protection compound buoyant cable in a kind of Haihe River is by comprising in the sheath that two unit constitute: wherein a unit is that 6 type shielding twisted-pair feeders of two pairs of adhesions are right; Line is to being coated with insulating barrier; Line between the gap carry out signal shielding after filling water-blocking material; Coat waterstop on the signal shielding layer, extrude the environmental-protecting foam material sheath then; Another unit is that electric pressure is the electrical control cable of 450/750V, and the copper conductor that insulate with many Halogen high density is a conductor, and conductor is covered with electrical control shielding layer outward, extrudes foaming halogen-free environmental material guards then.Two unit are formed circular, and in the middle of two pairs of unit, added many high strength fiber that blocks water, fill water-blocking material simultaneously, extrude the high density foaming sheath sheath of double-deck halogen-free environmental at last.
Said twisted-pair feeder adopts inflation high density polyethylene (HDPE) foam to insulating barrier.
Said twisted-pair feeder signal shielding layer adopts the wrapped and braiding double shield layer of paper tinsel layer.
Said electrical control shielding layer adopts alloy silk braid.
The utility model has the advantages that:
1, the density of cable is reduced, and can strengthen the mechanical strength of cable, can satisfy the instructions for use that frequent bending is not ruptured again; Ensure stressed evenly, the useful life that helps strengthening cable; Core plays the protection that blocks water reliably, can prevent fully that also sea (river) water enchroachment (invasion) from attacking.And cable all adopts ep-type material, can prevent that raw material from decomposing the pollution that the back produces through the long period of soaking of seawater or river.
2, the global density that makes cable is less than 1.0g/cm
3, can bubble through the water column, be convenient to safeguard; Have good flexibility, solve the problem of frequent folding and unfolding, and simple in structure, be convenient to processing and manufacturing; Guarantee cable insulation jacket original mechanical physics and electric property, have signal transmission and the effect of electrical control two-way function simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1 conductor; 2 electrical controls shielding layer; 3 waterproof foaming layer sheaths; 4 signal shielding layers; 5 waterproof foaming layer sheaths; 6 fibers that block water; 7 fillers that block water; 8 oversheaths; 9 waterstops.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: as shown in Figure 1; Special environment protection compound buoyant cable in a kind of Haihe River is by comprising in the sheath that two unit constitute: wherein a unit is that 6 type shielding twisted-pair feeders of two pairs of adhesions are right; Line is to being coated with insulating barrier; Line between the gap carry out 4 shielding of signal shielding layer after filling water-blocking material, and on signal shielding layer 4, coat waterstop 9, extrude environmental-protecting foam material sheath 5 then; Another unit is that electric pressure is the electrical control cable of 450/750V, and the copper conductor that insulate with many Halogen high density is a conductor 1, the conductor 1 outer electrical control shielding layer 2 that is covered with, the electrical control shielding layer 2 outer foaming halogen-free environmental material guards 3 that is extruded with.Two unit are formed circular, and in the middle of two pairs of unit, added many high strength fiber 6 that blocks water, fill water-blocking material 7 simultaneously, extrude the high density foaming sheath sheath 8 of double-deck halogen-free environmental at last.
