Abstract
The utility mode relates to a waterproof cable which is characterized in that: an inner waterproof layer is arranged between an insulating layer and a conductor; an outer waterproof layer is arranged at the inner part of an outer protective layer; and a filling layer is arranged between the outer waterproof layer and the insulating layer. When the waterproof cable is in use, the inner waterproof layer benefits for absorbing, storing and discharging the humidity and the drying environment which are generated by temperature when the conductor is in unbalanced work, therefore, the humidity can be adjusted, and the wire consumption can be effectively reduced; and with the adoption of the outer waterproof layer and the filling layer, water drop can be prevented from immersing the cable radially, the waterproof capacity of the cable can be protected, therefore, the cable can work in water, the service life of the cable can be prolonged, and the costs of the overhaul and maintenance can be lowered.
Description
Technical field
The utility model relates to the technical field of cable, specifically a kind of water-proof cable.
Background technology
Nowadays along with the continuous development of science and technology, various electric power, transmission of Information network are very extensive, the purposes of cable is expansion greatly also, be widely used in places such as harbour, harbour, hydroelectric station, reservoir, tunnel, the place that cable is settled is also very complicated, usually work in a humid environment, some in addition to touch water, at underwater work, this is just to the waterproof requirement height very of cable.
Existing cable generally is made of conductor, insulation, shielding and sheath, and the water resistance of this cable is very weak, and useful life is short, and in use, need regularly overhaul, and so not only waste of manpower increases cost, also has very big potential safety hazard simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of improved water-proof cable, and it is very weak that it can overcome the water resistance of cable in the prior art, the some shortcomings that useful life is short.
To achieve these goals, the technical solution of the utility model is: a kind of water-proof cable, it mainly comprises conductor, is located at conductor outer insulating barrier and outer jacket, it is characterized in that: be provided with the inner waterproofing layer between insulating barrier and the conductor, the inside of outer jacket is provided with exterior waterproof coating, is provided with packed layer between exterior waterproof coating and the insulating barrier.
During use; the humidity and the dry atmosphere that produce because of temperature when inner waterproofing layer of the present utility model helps absorbing, store, discharge the work of conductor dissymmetry; play the adjusting wetness action; effectively reduce the line consumption; exterior waterproof coating and packed layer can play and prevent the globule from radially invading cable, and the water resistance of protection cable makes the cable can be at underwater work; prolong the service life of cable simultaneously, the cost that has reduced maintenance and safeguarded.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprise be provided with conductor 1 in outer jacket 6, the outer jacket, conductor is wrapped with insulating barrier 3, its difference with the prior art is: be provided with inner waterproofing layer 2 between insulating barrier and the conductor, the inside of outer jacket is provided with exterior waterproof coating 5, is provided with packed layer 4 between exterior waterproof coating and the insulating barrier.The inner waterproofing layer adopts that strip material is wrapped to form, and strip material is a polyester belt, and the thickness of polyester belt is 0.01-0.08mm, and width is more than or equal to 5mm.Exterior waterproof coating adopts double-sided insulation waterstop, single face insulation waterstop or wrapped the forming of reinforced nonwoven fabrics waterstop.The thickness of double-sided insulation waterstop is 0.15-0.5mm; Single face insulation waterstop is made up of high-strength polyester nonwoven fabrics, high hydroscopic resin and adhesive, and thickness is 0.15-0.3mm; The thickness of reinforced nonwoven fabrics waterstop is 0.3-0.5mm.Packed layer is filled by waterproofing rope and is formed, and waterproofing rope is the rope shape materials that is composited by polyester fiber, adhesive and rapid expanding water-absorbing resin, and the diameter of waterproofing rope is 2.0-15mm.Be provided with three conductors in the outer jacket, every conductor is provided with inner waterproofing layer and insulating barrier outward.
In force, be provided with three conductors in the outer jacket, every conductor all is provided with inner waterproofing layer and insulating barrier outward separately, the inner waterproofing layer adopts that polyester belt is wrapped to form, the thickness of polyester belt is 0.02mm, and width is 5mm, the humidity and the dry atmosphere that produce because of temperature when the inner waterproofing layer helps absorbing, store, discharge the work of conductor dissymmetry, play the adjusting wetness action, effectively reduce the line consumption.Exterior waterproof coating employing single face insulate, and waterstop is wrapped to form; single face insulation waterstop is made up of high-strength polyester nonwoven fabrics, high hydroscopic resin and adhesive; thickness is 0. 3mm; exterior waterproof coating and packed layer can play and prevent that the globule is from radially invading cable; the water resistance of protection cable; make cable prolong the service life of cable simultaneously, the cost that has reduced maintenance and safeguarded at underwater work.
