Description
Technical field
The utility model belongs to cable preparation field, is specifically related to a kind of Novel water-proof cable.
Background technology
The demand of water-proof cable in recent years in heavy construction is increasing, water-proof cable must be used under the environment of humidity, ponding, 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 analysis in the past to cable quality accident, the intake consequence that causes of cable more and more causes the attention of cable manufacturer, requires also more and more higher to the water resistance of cable.
Summary of the invention
The utility model 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 advanced person, correlation standard requirement can be met, meet consumers' demand, its insulation resistivity >=1015 Ω cm, can water permeabillity test be successfully passed, there is superpower proof voltage ability.
the utility modeltechnical scheme be:
A kind of Novel water-proof cable, be provided with circular waterstop, three cable cores are had in waterstop internal package, described cable core inside is provided with conductor, the outer wrap of described conductor a polyolefin inner semiconductor layer, at a polyolefin inner semiconductor layer periphery parcel crosslinked polyetylene insulated layer, outside crosslinked polyetylene insulated layer, comprise a polyolefin out semiconductor layer, wrap up a copper strip shielding layer at polyolefin out semiconductor layer; Non-hygroscopic packed layer is provided with between cable core; A polyethylene bedding in the outer wrap of waterstop, a steel band in the outer wrap of polyethylene bedding, 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 beneficial effects of the utility model are:
The utility model is rational in infrastructure, and manufacturing process and technological process advanced person, can meet correlation standard requirement, meet consumers' demand, its insulation resistivity >=1015 Ω cm, can successfully pass water permeabillity test, has superpower proof voltage ability.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model cross section structure schematic diagram;
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.
Embodiment
Shown in Figure 1, the utility model is provided with circular waterstop 7, three cable cores are had in waterstop 7 internal package, described cable core inside is provided with conductor 1, the outer wrap of described conductor 1 a polyolefin inner semiconductor layer 2, at a polyolefin inner semiconductor layer 2 periphery parcel crosslinked polyetylene insulated layer 3, outside crosslinked polyetylene insulated layer 3, comprise 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 is provided with between cable core; A polyethylene bedding 8 in the outer wrap of waterstop 7, a steel band 9 in the outer wrap of polyethylene bedding 8, 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 construction, Novel water-proof cable demand also increases.Meanwhile, user also more and more payes attention to for the requirement of cable waterproof performance, and therefore, the utility model can be enterprise and creates considerable economic benefit.The described construction of cable is reasonable, and manufacturing process and technological process advanced person, can meet correlation standard requirement, meet consumers' demand, its insulation resistivity >=1015 Ω cm, can successfully pass water permeabillity test, has the proof voltage ability of superpower 1800V.
