Abstract
The utility model discloses a novel waterproof power cable and relates to the field of cables. The novel waterproof power cable is characterized in that a core comprises a conductor, an insulation layer, a shield layer and an isolation layer. The insulation layer is wrapped outside the conductor. The shield layer is wrapped outside the insulation layer. The isolation layer is arranged outside the shield layer. An inner protection layer arranged outside the core is internally provided with two cores of a composite winding structure. An outer protection layer is arranged outside the inner protection layer. A cavity is formed between the cores and the inner protection layer. Fillings are filled in the cavity. A waterproof elastic ferrule is arranged at each joint part of the power cable. The novel waterproof power cable disclosed by the utility model has the characteristics of good longitudinal and radial waterproof property, high stability and safety, long service life, high tensile strength, corrosion resistance, difficulty in fracture, good shielding property, excellent electrical conductivity, and capability of dissipating heat easily.
Description
Technical fieldThe utility model relates to field of cables, specifically relates to a kind of novel cable that blocks water.
Background technologyThe conventional cable that blocks water is in necessity protection of moisture content during to cable intrusion, outside core or cable core, applies various material water-proof materials usually, forms the cable that blocks water, and the water blocking layer of these cables all seriously hinders the heat radiation of cable self, influences the safe operation of cable.Or adopt the sheath waterproof, and sheath is perishable, break, in case influenced by extraneous factor, sheath breaks and has then lost water stop function, causes power supply trouble, and function of shielding and electric conductivity are brought negative influence.And usually blocking water of power cable is in the outer employing of the insulated wire cores design that radially blocks water; Promptly wrapping has waterstop outside stranded conductor, can only water resistance be terminated in outside the cable core usually, promptly radially blocks water; But because conductor is not taked the measure of blocking water; Water can infiltrate from end conductor, vertically moves along the conductor gap, does not reach vertical resistance effect.
Summary of the inventionIn view of the defective that prior art exists, the purpose of the utility model be to provide a kind of vertically, radially block-water performance is good, and is stable and safe, the cable long service life; Tensile strength is high, and is corrosion-resistant, is difficult for breaking; Advantages of good shielding performance, electric conductivity is good, the vaporific novel cable that blocks water of heat.
In order to solve the problem that the existing cable that blocks water exists, the technical solution of the utility model is: a kind of novel cable that blocks water comprises: core, conductor, insulating barrier, screen, separator, sheath, outer jacket, cavity, filler, cutting ferrule; Core comprises conductor, insulating barrier, screen, separator, and at conductor outerwrap insulating barrier, lapped shielding layer outside insulating barrier, screen are provided with separator outward; Outside at core is provided with sheath, comprises two cores in the sheath, is compound winding construction, and sheath is provided with outer jacket outward.Between core and sheath, be provided with cavity, be beneficial to distributing of heat.Filler is housed in the cavity.Joint at cable is provided with the elastic ferrule that blocks water, and plays a part vertically to block water.
Conductor is that the outer gasification of carbon fiber carbofrax material is processed.Insulating layer material is the copolymer (FEP) of tetrafluoroethene and perfluoropropene.Screen adopts the netted braiding of aluminium one polythene material to form.Separator adopts the compound soft PVDC material of water-proofing powder to process.Filler adopts bibulous resin material to process.Sheath is that composite braided water blocking yarn material is processed.Separator, filler and sheath play three layers and block water.Outer jacket adopts mica material to process, and the mica material temperature tolerance is good.Cutting ferrule employing elasticity polytetrafluoroethylplastic plastic is preferably processed.
Because the utlity model has vertically, radially block-water performance is good, and is stable and safe, the cable long service life; Tensile strength is high, and is corrosion-resistant, is difficult for breaking; Advantages of good shielding performance, electric conductivity is good, the vaporific characteristics of heat; Can carry out the production of mass, be a kind of new product with promotional value.
