Abstract
The utility model relates to a waterproof cross-linked power cable, which comprises an insulated conductor; two layers of belt lining, an isolating sleeve, a steel tape armored layer and an outer protective cover are subsequently arranged outside the insulated conductor from inside to outside; the waterproof cross-linked power cable is characterized in that the belt lining is wrapped by a water blocking tape; an aluminum-plastic composite tape longitudinal application layer is arranged between the two layers of belt lining; and the isolating sleeve and the outer protective cover are made of high-density polyethylene. The waterproof cross-linked power cable has the advantages that because the water-tightness of the high-density polyethylene is more than ten times higher than that of polyvinyl chloride, and the aluminum-plastic composite tape longitudinal application layer is added, the waterproof cross-linked power cable can meet the radial water blocking requirements when the cable is laid in water or very wet environment; because the water blocking tape can expand quickly, reach a certain height and form high-strength gel after touching water, the composite structure can meet the longitudinal water blocking requirement of the cable. Therefore, the waterproof cross-linked power cable has good waterproof performance and long service life.
Description
Technical field
The utility model relates to a kind of at the waterproof cross-linked power cable that can work under wet environment.
Background technology
The waterproof cross-linked power cable is used for extremely moist cable trough or uses in the medium occasion of water in short-term, existing common cross-linked power cable is to be made of insulated wire cores, nonwoven fabrics band lining, polyvinyl chloride separation sleeve, steel-tape armouring layer and polyvinyl chloride oversheath, and described insulated wire cores is made up of conductor, conductor shield, crosslinked polyetylene insulated layer, insulation screen and copper strips screen.Because the molecule of polyvinyl chloride is a polarity, the hydrone of polarity very easily is immersed on cable conductor and the insulating barrier by polyvinyl chloride layer, conductor can cause oxidation to increase conductor resistance after meeting water, increase the energy loss of transmission line, can produce water after the insulating barrier suction and set, make that operating cable takes place to puncture and damage; The water resistance of nonwoven fabrics band lining is poor simultaneously.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that existing product exists, and provides a kind of water resistance good, the waterproof cross-linked power cable of long service life.
The utility model is achieved in that it comprises insulated wire cores, outer rim in insulated wire cores is provided with two-layer band lining, separation sleeve, steel-tape armouring layer and oversheath from the inside to the outside successively, its special character is: described band lining is to form by waterstop is wrapped, be provided with the aluminum plastic composite belt longitudinal covering between two-layer band lining, the material of described separation sleeve and oversheath is a high density polyethylene (HDPE).
Above-mentioned waterproof cross-linked power cable, described insulated wire cores is three, internal layer band lining in the described two-layer band lining is wrapped in the outer rim of three eradication edge cores, and the gap location between insulated wire cores and internal layer band lining is filled with the inserts that blocks water, to improve water resistance.
The utility model has the advantages that: because the water-stop of high density polyethylene (HDPE) is than high tens of times of polyvinyl chloride, adding has increased the aluminum plastic composite belt longitudinal covering, can satisfy in water or the extremely requirement that radially blocks water in the environment of humidity of cable laying; Can expand rapidly because waterstop is met water, and can reach certain height and can form high-intensity gel, this composite construction can satisfy the requirement that vertically blocks water of cable completely.Therefore the water resistance of this waterproof cross-linked power cable is good, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model (corresponding embodiment 1);
Fig. 2 is structural representation of the present utility model (corresponding embodiment 2).
Among the figure: oversheath 1, steel-tape armouring layer 2, separation sleeve 3, band lining 4, aluminum plastic composite belt longitudinal covering 5, band lining 6, insulated wire cores 7, inserts 8 blocks water.
Embodiment
Embodiment 1
As shown in Figure 1, the utility model has an insulated wire cores 7, outer rim in insulated wire cores 7 is enclosed with band lining 6, aluminum plastic composite belt longitudinal covering 5, band lining 4, separation sleeve 3, steel-tape armouring layer 2 and oversheath 1 from the inside to the outside successively, described band lining 4 and band lining 6 are to form by waterstop is wrapped, and the material of described separation sleeve 3 and oversheath 1 is a high density polyethylene (HDPE).
As shown in Figure 2, the utility model has three insulated wire cores that are triangularly arranged 7, be enclosed with band lining 6, aluminum plastic composite belt longitudinal covering 5, band lining 4, separation sleeve 3, steel-tape armouring layer 2 and oversheath 1 from the inside to the outside successively in three outer rims of thoroughly doing away with edge core 7, described band lining 4 and band lining 6 are to form by waterstop is wrapped, and the material of described separation sleeve 3 and oversheath 1 is a high density polyethylene (HDPE).Gap location between insulated wire cores 7 and internal layer band lining 6 is filled with the inserts 8 that blocks water, to improve water resistance.
Claims (2)
1, a kind of waterproof cross-linked power cable, comprise insulated wire cores, outer rim in insulated wire cores is provided with two-layer band lining, separation sleeve, steel-tape armouring layer and oversheath from the inside to the outside successively, it is characterized in that: described band lining is to form by waterstop is wrapped, be provided with the aluminum plastic composite belt longitudinal covering between two-layer band lining, the material of described separation sleeve and oversheath is a high density polyethylene (HDPE).
2, waterproof cross-linked power cable according to claim 1, it is characterized in that: described insulated wire cores is three, internal layer band lining in the described two-layer band lining is wrapped in the outer rim of three eradication edge cores, and the gap location between insulated wire cores and internal layer band lining is filled with the inserts that blocks water.
