Abstract
The present invention relates to a kind of novel water-proof cable, the core of the water-proof cable is conductor, the conductor is copper conductor or aluminium conductor, in the outer layer covers halogen-free and low-smoke flame-retardant polyolefin insulating barrier of conductor, copper strip shielding layer in the outer wrap of halogen-free and low-smoke flame-retardant polyolefin insulating barrier, a kind of waterstop in the outer wrap of copper strip shielding layer, in the outer wrap of waterstop halogen-free and low-smoke flame-retardant polyolefin sheathed.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.
Description
Technical field
The invention belongs to cable preparation field, and in particular to a kind of novel water-proof cable.
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 novel water-proof cable, 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 technical scheme is that：
A kind of novel water-proof cable, the core of the water-proof cable is conductor, the conductor is copper conductor or aluminium conductor, in the outer layer covers halogen-free and low-smoke flame-retardant polyolefin insulating barrier of conductor, copper strip shielding layer in the outer wrap of halogen-free and low-smoke flame-retardant polyolefin insulating barrier, a kind of waterstop in the outer wrap of copper strip shielding layer, in the outer wrap of waterstop halogen-free and low-smoke flame-retardant polyolefin sheathed.
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.
Fig. 1 is cross section structure schematic diagram of the present invention；
In figure：1st, conductor；2nd, halogen-free and low-smoke flame-retardant polyolefin insulating barrier；3rd, copper strip shielding layer；4th, waterstop；5th, it is halogen-free and low-smoke flame-retardant polyolefin sheathed.
Specific embodiment
It is shown in Figure 1, core of the invention is conductor 1, the conductor 1 is copper conductor or aluminium conductor, in the outer layer covers halogen-free and low-smoke flame-retardant polyolefin insulating barrier 2 of conductor 1, halogen-free and low-smoke flame-retardant polyolefin insulating barrier 2 is main to be made by polyolefine material, copper strip shielding layer 3 in the outer wrap of halogen-free and low-smoke flame-retardant polyolefin insulating barrier 2, copper strip shielding layer 3 constitutes screen layer after being wound by copper strips, a kind of waterstop 4 in the outer wrap of copper strip shielding layer 3, waterstop 4 is made up of one layer of watertight material, halogen-free and low-smoke flame-retardant polyolefin sheathed 5 in the outer wrap of waterstop 4.Subway construction is in the gold period of development.While iron base Facilities Construction in large quantities, water-proof cable demand 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.
