Description
Technical field
The present invention relates to a kind of cable, and in particular to a kind of cable for ship.
Background technology
With the application of converter technique, application is also begun to suitable for the cable of variable-frequency power sources, it is symmetrical that marine variable-frequency cable does not require nothing more than conductor structure, increase screen layer, suppressing, higher harmonic voltage is cumulative to cause insulation breakdown and can be anti-interference, meanwhile, because cable is using aboard ship or on oil platform, moisture content is easily contacted, so cable is needed with water resistance.General stop water can cause cable weight heavier, can increase the load of ship, so the characteristics of Structural Design Requirement of cable keeps cable weight light small volume.
The content of the invention
Goal of the invention：The invention aims to overcome deficiency of the prior art, there is provided one kind is applied to variable-frequency power sources, and small volume is lightweight, and the cable for ship with water resistance.
Technical scheme：In order to solve above-mentioned technical problem，A kind of light-duty waterproof frequency conversion cable for ship of the present invention，It includes main line core conductor，The first insulating barrier is provided with outside the main line core conductor，Extrude outside first insulating barrier and be provided with the first waterproofing type semiconductive shielding layer，First insulating barrier is formed with the first waterproofing type semiconductive shielding layer double-layer coextrusion，The main line core conductor、First insulating barrier and the first waterproofing type semiconductive shielding layer composition main line core unit，The main line core unit sets altogether three，It is tangent outside the adjacent main line core unit to be provided with ground wire core unit，The ground wire core unit includes ground wire core conductor，The second insulating barrier is provided with outside the ground wire core conductor，Extrude outside second insulating barrier and be provided with the second waterproofing type semiconductive shielding layer，Second insulating barrier is formed with the second waterproofing type semiconductive shielding layer double-layer coextrusion，Waterproof packed layer is provided with outside the main line core unit and ground wire core unit，It is wrapped outside the waterproof packed layer to be provided with semiconductor waterstop，Light-duty waterproof inner sheath is provided with outside the semiconductor waterstop，Metal screen layer is provided with outside the light-duty waterproof inner sheath，Fire-retardant oversheath is provided with outside the metal screen layer.
The main line core conductor and ground wire core conductor all press circular configuration or multiple twisted wire soft structure for tin plating.
First insulating barrier and the second insulating barrier are all halogen-free type crosslinked polyethylene or the insulating barrier of second third.
The waterproof packed layer is light-duty waterproofing rope packed layer.
The waterproof inner sheath is LLDPE sheath.
The metal screen layer is wrinkle aluminium-alloy pipe or wrinkle copper alloy or corrugated copper tube.
The fire-retardant oversheath is high oxygen index (OI) polyvinyl chloride or the low cigarette polyolefin jacket of high-flame-retardanthalogen-free halogen-free.
The insulating barrier and screen layer of the main line core unit and ground wire core unit is extruded by the way of double-layer coextrusion, it is fully bonded to together, very close to each other, to prevent water part from entering, screen layer is compatible with insulating barrier, i.e. when insulating materials is that second third insulate, semiconductive blocks water screen layer with the matrix of materials of second third, adds semiconductive carbon black, and hydrophobic material nano-calcium carbonate about 15-20 parts are added in then filling a prescription, nano zine oxide about 0.8-1 parts, such semiconductive screen layer that blocks water just is provided with block-water performance.
Ground wire core unit is divided into three parts by the present invention, it is respectively interposed among the gap of main line core unit, form symmetrical structure, suppress adding up for the higher harmonic voltage produced in conversion process, insulated from the insulating materials crosslinked polyethylene or second third of high-quality simultaneously, enable cable to bear the pulse voltage that frequency conversion causes.The waterproofing type semiconductive shielding layer extruded outside insulating barrier, not only acts as elimination insulating surface stress, the stress cracking insulated when bending is prevented, while adding the lyophobic dusts such as nanomete talc powder, nano zine oxide in the insulation shielding layer formula plays block-water performance.So, outside moisture and moisture also are difficult to enter into insulating barrier, it is ensured that the insulating properties of cable, and prevent the generation of water tree.Light-duty material water-proof material is being filled into outside cable core, metal screen layer is set outside the water proof type inner sheath for extruding, metal screen layer is mainly using wrinkle aluminium-alloy pipe or wrinkle copper alloy or corrugated copper tube, the external interference in magnetic field during cable use is reduced, the pollution to environment during frequency-changing cable use is eliminated.Extruding light-duty water proof type inner sheath into outside cable core, oversheath adopts high resistant combustible material, cable not only waterproof but also fire-retardant.
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：Overall structure of the present invention arranges reasonable, suitable for variable-frequency power sources, using symmetrical structure, cable is set to bear the pulse voltage that frequency conversion causes, using the insulating barrier and screen layer of double-layer coextrusion, ensure that the insulating properties of cable, and prevent the generation of water tree, using waterproof inner sheath and fire-retardant oversheath, cable not only waterproof but also fire-retardant, using corrugated metal screen layer, reduce the external interference in magnetic field during cable use, eliminate the pollution to environment during frequency-changing cable use, with reference to the cooperation of remaining each layer, cable overall volume is little, it is lightweight, meet cable for ship requirement.
