Abstract
The invention relates to a novel waterproof cable. The novel waterproof cable is provided with a circular water-blocking tape, the water-blocking table internally wraps three cable cores, each cable core is internally provided with conductors, the conductors of each cable core are externally wrapped by a polyolefin internal semiconducting shielding layer, the periphery of each polyolefin internal semiconducting shielding layer is wrapped by a crosslinking polyethylene insulating layer, each crosslinking polyethylene insulating layer is externally wrapped by a polyolefin external semiconducting shielding layer, each polyolefin external semiconducting shielding layer is wrapped by a copper strip shielding layer; a non-hygroscopic filling layer is arranged between the cable cores; the water-blocking tape is externally wrapped by a polyethylene cushion layer, the polyethylene cushion layer is externally wrapped by a steel band, the steel band is composed of an alloy steel material, the outer side of the alloy steel material is coated with paint or plated with zinc, and the steel band is externally wrapped by a polyvinyl chloride sheath. The novel waterproof cable is reasonable in structure and advanced in manufacturing process and technical flow, can meet stipulations and requirements of correlation standards, and meets user demands.
Description
Technical field
The invention belongs to cable preparation field, be specifically related to a kind of Novel water-proof cable.
Background technology
The water-proof cable demand in heavy construction in recent years is increasing, must use water-proof cable under the environment of moist, hydrops, and the cable used in the ocean development project of coastal area all has waterproof requirement, and the cable used in metro project also has waterproof requirement.In the conventional analysis to cable quality accident, the consequence that cable water inlet causes increasingly causes the attention of cable manufacturer, requires also more and more higher to the water resistance of cable.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, propose a kind of Novel water-proof cable, the described construction of cable is reasonable, manufacturing process and technological process are advanced, correlation standard requirement can be met, meet user's request, its insulation resistivity >=1015 Ω cm, water permeabillity test can be successfully passed, there is superpower proof voltage ability.
The present inventionTechnical scheme be:
A kind of Novel water-proof cable, it is provided with the waterstop of circle, three cable cores are had in waterstop internal package, it is provided with conductor inside described cable core, the outer wrap of described conductor a polyolefin inner semiconductor layer, wrap up a crosslinked polyetylene insulated layer in polyolefin inner semiconductor layer periphery, outside crosslinked polyetylene insulated layer, include a polyolefin out semiconductor layer, wrap up a copper strip shielding layer at polyolefin out semiconductor layer；Non-hygroscopic packed layer it is provided with between cable core；Outer wrap at waterstop a polyethylene bedding, and the outer wrap at polyethylene bedding a steel band, and described steel band is made up of alloy steel material, in the japanning or zinc-plated of the outside of alloy steel material, a pvc sheath in steel band outer wrap.
The invention has the beneficial effects as follows:
Present configuration is reasonable, and manufacturing process and technological process are advanced, can meet correlation standard requirement, meet user's request, and its insulation resistivity >=1015 Ω cm can successfully pass water permeabillity test, have superpower proof voltage ability.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is cross section structure schematic diagram of the present invention；
In figure: 1, conductor；2, polyolefin inner semiconductor layer；3, crosslinked polyetylene insulated layer；4, polyolefin out semiconductor layer；5, copper strip shielding layer；6, non-hygroscopic packed layer；7, waterstop；8, polyethylene bedding；9, steel band；10, pvc sheath.
Detailed description of the invention
Shown in Figure 1, the present invention is provided with the waterstop 7 of circle, three cable cores are had in waterstop 7 internal package, conductor 1 it is provided with inside described cable core, the outer wrap of described conductor 1 a polyolefin inner semiconductor layer 2, at polyolefin inner semiconductor layer 2 one crosslinked polyetylene insulated layer 3 of peripheral parcel, outside crosslinked polyetylene insulated layer 3, include a polyolefin out semiconductor layer 4, wrap up a copper strip shielding layer 5 at polyolefin out semiconductor layer 4；Non-hygroscopic packed layer 6 it is provided with between cable core；Outer wrap at waterstop 7 polyethylene bedding 8, outer wrap at polyethylene bedding 8 steel band 9, described steel band 9 is made up of alloy steel material, in the japanning or zinc-plated of the outside of alloy steel material, a pvc sheath 10 in steel band 9 outer wrap.Described conductor 1 is copper conductor or aluminium conductor.While a large amount of infrastructure constructions, Novel water-proof cable demand also increases.Meanwhile, user also increasingly payes attention to for the requirement of cable waterproof performance, and therefore, the present invention can create considerable economic benefit for enterprise.The described construction of cable is reasonable, and manufacturing process and technological process are advanced, can meet correlation standard requirement, meet user's request, and its insulation resistivity >=1015 Ω cm can successfully pass water permeabillity test, have the proof voltage ability of superpower 1800V.
