Abstract
The invention discloses a self-repairing waterproof cable. The self-repairing waterproof cable comprises a cable core formed by intertwisting a plurality of wire cores, wherein a radial water-blocking buffer layer, a self-repairing water-blocking sheath and an outer sheath are coated outside the cable core; and a self-repairing filling material is filled in the gaps among the wire cores and between the wire cores and the radial water-blocking buffer layer. The self-repairing waterproof cable has the advantages that: water can be blocked and stopped effectively in the longitudinal direction and the radial direction; and when the outer sheath has a local damage and water ingresses into the sheath, the self-repairing water-blocking sheath absorbs water and expands to automatically make up the local damage of the outer sheath, prevent the excessive intrusion of the water and ensure the safe use and the service life of the cable.
Description
Technical field
The present invention relates to the electric wire field, is a kind of self-repairing waterproof cable specifically.
Background technology
The quality of laying of electric wire directly influences its serviceability, especially lay the comparatively complicated abominable occasion of environment, the local damage of oversheath appears in electric wire unavoidably in installation, use, extraneous moisture is invaded gradually, make insulation resistance descend, become and bring out the electric wire cause faults, released the cable that blocks water on the market for this reason.
Mostly the cable that generally blocks water is to utilize the less performance of polythene material water transit dose, extrude the layer of polyethylene watertight composition, though can play radially water-proof function to a certain extent, can not effectively cram automatically oversheath local damage position, remedy damage location.If be damaged simultaneously, even very slight damage just the polyethylene waterproof layer can lose the function of its waterproof, can't guarantee the built-in electrical insulation performance at the polyethylene waterproof layer.
Summary of the invention
The objective of the invention is provides a kind of self-repairing waterproof cable in order to overcome the deficiencies in the prior art, and it can realize benefit certainly, the self-regeneration function of cable, prevents the excessive intrusion of extraneous moisture, guarantees cable safe in utilization and useful life.
In order to solve the problems of the technologies described above, a kind of self-repairing waterproof cable of the present invention comprises by the stranded cable core that forms of some cores, is coated with radially water-blocking buffer layer, autocompensation type block water cover and oversheath successively in cable core outside; In the gap between the core and core and radially be filled with the autocompensation type filler between the water-blocking buffer layer.
Described core comprises conductor and is extruded in the insulating barrier of conductor outside
Adopt the intumescent material water-proof material to fill among the present invention, can guarantee that vertical waterproof of cable conductor and electric property are stable as autocompensation type.
Compared with prior art, advantage of the present invention is owing in the autocompensation type cover inboard that blocks water one water-blocking buffer layer radially is set, outside blocking water cover, autocompensation type coats oversheath, filler adopts autocompensation type to fill, make this cable vertically and radially can both block water effectively, waterproof, when oversheath local damage occurs water intrusion is arranged, autocompensation type blocks water and overlaps the beginning imbibition, automatically remedy oversheath and local damage occurs, under autocompensation type blocks water the simultaneously impaired situation of cover, but also imbibition, the self-regeneration breakage, prevent the excessive intrusion of moisture, guarantee cable safe in utilization and useful life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of self-repairing waterproof cable of the present invention, comprise oversheath 6, autocompensation type block water cover 5, water-blocking buffer layer 4 radially from outside to inside successively, radially be provided with a plurality of cable cores in the water-blocking buffer layer 4, between each cable core and the cable core and cable core and radially be provided with autocompensation type between the water-blocking buffer layer 4 and fill 3; Described cable core comprises conductor 1 and insulating barrier 2, and insulating barrier 2 is extruded in conductor 1 outside.Wherein autocompensation type filling 3 is the intumescent material water-proof material.
The present invention has following characteristics:
1,, guaranteed that vertical waterproof of cable conductor and electric property are stable in the gap between the core and core and radially be filled with the autocompensation type filler between the water-blocking buffer layer;
2, in the autocompensation type cover inboard that blocks water one water-blocking buffer layer radially is set, coats oversheath in the autocompensation type cover outside that blocks water, filler adopts autocompensation type to fill.This cable vertically and radially can both block water effectively, waterproof, when oversheath local damage occurred water intrusion is arranged, the autocompensation type cover beginning imbibition that blocks water remedied oversheath automatically and local damage occurs, prevent the excessive intrusion of moisture, guarantee cable safe in utilization and useful life.
The above only is a preferred implementation of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
