For floating cable, except meeting common cable, bear stretching and frequent crooked grade general performance requirement, key is that cable must be able to float on the surface.Present floating cable generally comprises sheath, electric conductor and buoyancy aid, and electric conductor is positioned at the centre of buoyancy aid and sheath, is arranged above and below, and electric conductor is generally copper conductor, and buoyancy aid is generally the solid materials such as foam.Its weak point is: copper conductor density is large, and buoyancy is restricted, if copper conductor is too little, affects again the transmission performance of cable; If employing aluminium conductor, its mechanical strength is low, poor toughness, easily fractures; In addition, the water resistance of cable is inadequate.
Summary of the invention
The object of the present invention is to provide a kind of marinely with the power cable of swimming, solve existing cable and can not meet the problems such as water resistance, the buoyancy of use is at sea inadequate.
Technical scheme of the present invention is:
A kind of marine with the power cable of swimming; this cable is provided with conductor, the first fish tail and waterproof layer, the first Thermoplastic Vulcanizate insulating barrier, float, the second fish tail and waterproof layer, polyurethane jacket, the second Thermoplastic Vulcanizate insulating barrier, reinforcement, sealant, the 3rd fish tail and waterproof layer, wherein:
The center of cable is reinforcement, in the outside of reinforcement, it is float, in the outside of float, it is the 3rd fish tail and waterproof layer, in the outside of the 3rd fish tail and waterproof layer, it is sealant, the conductor that is two-layer even annular array in the outside of sealant: ground floor conductor and second layer conductor, in the outside of described two-layer even annular array conductor, it is the second fish tail and waterproof layer, in the outside of the second fish tail and waterproof layer, it is the first Thermoplastic Vulcanizate insulating barrier, in the outside of the first Thermoplastic Vulcanizate insulating barrier, it is the insulated wire cores of the even annular array of one deck, described insulated wire cores is that the second Thermoplastic Vulcanizate insulating barrier of the 3rd layer of conductor and its outside forms.
The described power cable of swimming for sea, is the first fish tail and waterproof layer in the outside of described insulated wire cores, in the outside of the first fish tail and waterproof layer, is polyurethane jacket.
The invention has the beneficial effects as follows:
1, the present invention adopts Thermoplastic Vulcanizate (Thermoplastic Vulcanizate) insulating barrier; fish tail and waterproof layer adopts Thermoplastic Vulcanizate (TPV) material; sealant adopts Thermoplastic Vulcanizate (TPV) material, and reinforcement adopts Thermoplastic Vulcanizate bar.Have: 1. good elasticity and compression resistant morphotropism, resistance to environment, resistance to ag(e)ing are equivalent to ethylene propylene diene rubber, and its oil resistant solvent resistance is equally matched with polychloroprene rubber for general purpose simultaneously.2. the wide (– of temperature limit is 60 ~ 150 ℃).3. good processing characteristics.4. environmental protection, recyclable, and six performances of Reusability are without obvious decline, meet European Union environmental protection requirement.5. light specific gravity, presentation quality is even.
2, the present invention adopts polyurethane jacket, has splendid oil resistant and chemical solvent corrosive nature, tear-proof, and low temperature flexibility is good, and elasticity is strong, and stress buffer is good, wear-resisting withstand voltage.
3, float of the present invention adopts epoxy resin expanded material, has alleviated electric conductor weight.
4, the present invention, when alleviating electric conductor weight, has guaranteed the mechanism performance of current delivery amount and cable, because conductor outside is provided with three layers of fish tail and waterproof layer, has guaranteed the safety of cable.
