Abstract
The invention discloses a high-performance environment-protecting waterproof cable comprising a conductor positioned in the center of the cable. An inner acrylic polymer high-molecular waterproof layer wraps the inner insulating layer in an extruded mode. An outer insulating layer wraps the inner acrylic polymer high-molecular waterproof layer in an extruded mode. An outer acrylic polymer high-molecular waterproof layer wraps the outer insulating layer in an extruded mode. An oversheath on the outermost layer wraps the outer inner acrylic polymer high-molecular waterproof layer in an extruded mode. The high-performance environment-protecting waterproof cable of the invention has excellent water resistance, alkali resistance, acid-rain-resistance and long-acting mildew-resistance and antibiosis performance, and is environment friendly. The high-performance environment-protecting waterproof cable can replace a metal sheath in terms of waterproof technology. The high-performance environment-protecting waterproof cable can be applied to river cross or seabed working. The high-performance environment-protecting waterproof cable of the invention is simple in production technology, better in waterproof effect than an ordinary waterproof cable and small in material consumption. The high-performance environment-protecting waterproof cable has an operating period of 20 years and will not product any environmental pollution.
Description
Technical field
The present invention relates to and join field of cable technology, particularly relate to a kind of high-performance environment-friendly water-proof cable.
Background technology
Water-proof cable is applicable to immersible pump, colliery, underwater operation, and the water treatment facilities such as scape light modulation in water, cable allows the long period to be laid in water environment.
The waterproof type of cable is generally divided into longitudinal waterproof and radial waterproof two kinds.What longitudinal waterproof was generally commonly used has water blocking yarn, water-proofing powder and waterstop, their mechanism that blocks water meets water expandable material containing a kind of in these materials, when moisture content is from cable socket or after entering from sheath defect, this material will be met water undergoes rapid expansion and be stoped moisture content along cable longitudinally diffusion further, so just achieves the object of the longitudinal waterproof of cable.Radial waterproof then mainly through extruding the nonmetal sheath of HDPE or hot pressing, welding, cold-drawn metallic sheath mode realize.Cable radial water-resisting depends primarily on sheath material itself, longitudinal water-blocking mainly by the compactness of the construction of cable and material water-proof material (water blocking yarn ointment powder) with the use of.
The waterproof material more than adopted can play certain resistance effect, but adopt petroleum jelly considerably increase the weight of cable and cause the electric conductivity of cable conductor to decline, the seriously polluted constructional difficulties of butt joint, after cable is suitable for and repeatedly circumnutates in process, there is relative shift between the heart yearn of cable and inside and outside screen, produce small gap.The attached powder of water-proofing powder is more difficult, adopts when waterstop, water blocking yarn and the external diameter of cable can be caused to increase, heat radiation difficulty, thus accelerates transmission capacity of cable heat ageing and restriction cable etc.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides a kind of high-performance environment-friendly water-proof cable, efficiently solves above water-proof cable all problems that blocks water in the process of blocking water, reaches desirable block-water effect, light, and production technology is simple, reduces production cost.
A kind of high-performance environment-friendly water-proof cable of the present invention, comprise the conductor being positioned at cable center, inner insulating layer is extruded outside conductor, inner propene acid polymer family macromolecule water blocking layer is extruded outside inner insulating layer, external insulation layer is extruded outside inner propene acid polymer family macromolecule water blocking layer, outside external insulation layer, extrude outer acrylate copolymer family macromolecule water blocking layer, outermost layer extrudes oversheath.
Further improvement, the enough thickness of described inner insulating layer is 1/3 of external insulation layer thickness.
Further improvement, the thickness of described inner propene acid polymer family macromolecule water blocking layer is 1/2 of outer acrylate copolymer family macromolecule water blocking layer.
Compared with prior art, beneficial effect of the present invention is:
1, the performance of good water-fast, alkali resistant, acid rain preventing, long effect mould proof antibacterial is not only had, and environmental protection, the technique of metallic sheath waterproof can be replaced, can apply in seabed work of crossing the river across river; Production technology of the present invention is simple, and than the good water-proof effect of general water-proof cable, consumptive material is few, and the operating period reaches 20 years, without the generation of any environmental pollution.
2, external insulation design and inside and outside acrylate copolymer family macromolecule waterproof layer structure is adopted, running in water environment situation, stable normal operation can be kept, keep the integrality of circuit, there is good tensile strength, can effectively, acid rain strong in alkalescence, mould work, long service life.
3, external insulation thickness, the design of inside and outside acrylate copolymer family macromolecule waterproofing layer thickness adoption rate, make the performances such as the sealing of cable, rounding property greatly improve, also save cost simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of high-performance environment-friendly water-proof cable as shown in Figure 1, comprise the conductor 1 being positioned at cable center, inner insulating layer 2 is extruded outside conductor 1, inner propene acid polymer family macromolecule water blocking layer 3 is extruded outside inner insulating layer 2, external insulation layer 4 is extruded outside inner propene acid polymer family macromolecule water blocking layer 3, outside external insulation layer 4, extrude outer acrylate copolymer family macromolecule water blocking layer 5, outermost layer extrudes oversheath 6.
Wherein, the enough thickness of described inner insulating layer 2 is 1/3 of external insulation layer 4 thickness.
Wherein, the thickness of described inner propene acid polymer family macromolecule water blocking layer 3 is 1/2 of outer acrylate copolymer family macromolecule water blocking layers 5.
Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
