Description
Technical field
The invention belongs to cable preparation field, and in particular to a kind of zinc-plated cable of alloy.
Background technology
Demand of the water-proof cable in recent years in heavy construction is increasing, and water-proof cable must be used in the environment of moist, ponding, and the cable used in the ocean development project of coastal area has waterproof requirement, and the cable used in metro project also has waterproof requirement.In the past, in the analysis of cable quality accident, the consequence that cable water inlet is caused increasingly causes the attention of cable manufacturer, the water resistance to cable required also more and more higher.
The content of the invention
The present invention overcomes the deficiencies in the prior art, propose a kind of zinc-plated cable of alloy, the construction of cable is reasonable, manufacturing process and technological process are advanced, correlation standard requirement can be met, user's request is met, its insulation resistivity >=1015 Ω cm, water permeabillity test can be successfully passed, with superpower proof voltage ability.
The present inventionTechnical scheme be：
A kind of zinc-plated cable of alloy, it is provided with the waterstop of circle, there are three cable cores in waterstop internal package, conductor is provided with inside the cable core, the outer wrap of the conductor a polyolefin inner semiconductor layer, in polyolefin inner semiconductor layer periphery one crosslinked polyetylene insulated layer of parcel, a polyolefin out semiconductor layer is included outside crosslinked polyetylene insulated layer, a copper strip shielding layer is wrapped up in polyolefin out semiconductor layer；Non-hygroscopic packed layer is provided between cable core；A polyethylene bedding in the outer wrap of waterstop, a steel band in the outer wrap of polyethylene bedding, the steel band is made up of alloy steel material, in the outside japanning or zinc-plated of alloy steel material, a pvc sheath in steel band outer wrap.
The beneficial effects of the invention are as follows：
The present invention is rational in infrastructure, and manufacturing process and technological process are advanced, can meet correlation standard requirement, meets user's request, and its insulation resistivity >=1015 Ω cm can successfully pass water permeabillity test, with superpower proof voltage ability.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.

In figure：1st, conductor；2nd, polyolefin inner semiconductor layer；3rd, crosslinked polyetylene insulated layer；4th, polyolefin out semiconductor layer；5th, copper strip shielding layer；6th, non-hygroscopic packed layer；7th, waterstop；8th, polyethylene bedding；9th, steel band；10th, pvc sheath.
Specific embodiment
It is shown in Figure 1, the present invention is provided with the waterstop 7 of circle, there are three cable cores in the internal package of waterstop 7, conductor 1 is provided with inside the cable core, the outer wrap of the conductor 1 a polyolefin inner semiconductor layer 2, in the periphery of polyolefin inner semiconductor layer 2 one crosslinked polyetylene insulated layer 3 of parcel, a polyolefin out semiconductor layer 4 is included in the outside of crosslinked polyetylene insulated layer 3, a copper strip shielding layer 5 is wrapped up in polyolefin out semiconductor layer 4；Non-hygroscopic packed layer 6 is provided 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, the steel band 9 is made up of alloy steel material, in the outside japanning or zinc-plated of alloy steel material, a pvc sheath 10 in the outer wrap of steel band 9.The conductor 1 is copper conductor or aluminium conductor.While a large amount of infrastructure constructions, the zinc-plated cabling requirements amount of alloy also increases.Meanwhile, user also increasingly payes attention to for the requirement of cable waterproof performance, therefore, the present invention can be that enterprise creates considerable economic benefit.Rationally, manufacturing process and technological process are advanced for the construction of cable, can meet correlation standard requirement, meet user's request, and its insulation resistivity >=1015 Ω cm can successfully pass water permeabillity test, the proof voltage ability with superpower 1800V.
