Abstract
The invention discloses a 1KV and below extra-flexible variable-frequency cable for a vessel; the 1KV and below extra-flexible variable-frequency cable consists of a tin-plated copper conductor, an insulating layer, an insulation shielding layer, a filler, a wrapping layer, a copper wire weaving layer and an external jacket; the flexible insulating layer made of an insulating material with high temperature resistance is extruded on the single ultra-thin flexible tin-plated copper conductor; a corrugated copper tape or copper-plastic composite tape is wrapped on the insulating layer to form the wire core; the filler is filled among a plurality of the wire cores; a wrapping layer made from a halogen-free low-smoke low-toxic retardant material is wrapped at the periphery of the filler; the copper wire weaving layer is woven on the wrapping layer; and the external jacket made from a halogen-free low-smoke low-toxic retardant cross-linked polyolefin material is extruded on the copper wire weaving layer. The invention provides the 1KV and below extra-flexible variable-frequency cable for the vessel; the 1KV and below extra-flexible variable-frequency cable is suitable for a high-frequency circuit; the service life of the cable in the high-frequency circuit can be greatly prolonged and the electric performance can be improved; and the 1KV and below extra-flexible variable-frequency cable has small laying bending radius, is convenient to lay and install, is capable of saving a lot of usage space of the vessel and is low-smoke, halogen-free, low-toxic and retardant.
Description
Technical field
The present invention relates to technical field of electric wires and cables, particularly naval vessel frequency-changing cable is specially a kind of 1kV and following naval vessel with special soft frequency-changing cable.
Background technology
At present, the common crosslinked polyetylene insulated polyolefin jacket cable of general employing in the Ship System, the permission minimum bend inside radius of cable is 6 times the outside diameter of cable when laying.This is the typical products characteristic of cable for ship, can only be applicable to the frequency of 50HZ, can not satisfy the demand of growing Ship System high-frequency frequency conversion equipment.And the space that requires during this type of cable laying is large, has brought many inconvenience and trouble for the design on naval vessel and construction.
Summary of the invention
The purpose of this invention is to provide a kind of good electric property, long service life, lay bending radius little, be convenient to mounting and installation, and can save a large amount of naval vessels usage space, be applicable to the rated voltage 1kV of high-frequency current and following low smoke, zero halogen low-poison and combustion-resisting naval vessel with special soft frequency-changing cable.
Technical scheme of the present invention is: a kind of 1kV and following naval vessel are comprised of tinned copper conductor, insulating barrier, insulation screen, filler, lapping layer, proof copper-wire braided layer and oversheath with special soft frequency-changing cable.Extrude a layer insulating at single tinned copper conductor, the lapped insulation screen forms core on the insulating barrier, fills filler between many cores, at the peripheral wrapped one deck lapping layer of filler, at lapping layer braiding proof copper-wire braided layer, extrude oversheath at the proof copper-wire braided layer.
Every tinned copper conductor all adopts many superfine stranded the forming of soft tinned copper wire, the insulation screen that the peripheral wrapped embossing copper strips of insulating barrier or compound copper-plastics band consist of.
Lapping layer is made by low smoke, zero halogen low-poison and combustion-resisting material.
Oversheath is made by low smoke, zero halogen low-poison and combustion-resisting cross-linked polyolefin material.
The invention has the beneficial effects as follows: owing to wrapped embossing copper strips or compound copper-plastics band on the insulating barrier, at lapping layer braiding proof copper-wire braided layer.So that not producing to external world, do not disturb the electromagnetic induction of this cable itself, this frequency-changing cable be can be used in the higher circuit of frequency, cause even frequency wherein mutually whetstone disappears, and the odd frequency can rely on the knot title property elimination of cable, and clutter can rely on screen to eliminate; Also can fully eliminate the interference of outer this cable of bound pair.This all makes this cable electrical performance and used life all be greatly improved.Again because conductor adopts many stranded the forming of superfine copper wire, it is 4 times the outside diameter of cable that insulation adopts the flexibility material can make the permission minimum bend inside radius of cable when laying, and can save a large amount of naval vessel usage spaces.This cable also has the characteristics of low smoke, zero halogen low-poison and combustion-resisting.
Description of drawings
Accompanying drawing 1 is 1kV and following naval vessel with the structural representation of special soft frequency-changing cable.
Embodiment

Embodiments of the present invention are described with special soft frequency conversion three-core cable as example take the crosslinked polyetylene insulated cross-linked polyolefin sheath low smoke, zero halogen of 1kV low-poison and combustion-resisting naval vessel.
As shown in Figure 1: all extrude insulating barrier 2 that one deck by soft cross-linking polyethylene materials made by many on the stranded tinned copper conductor that forms 1 of thin zinc-plated soft thin copper wire at three.Wrapped embossing copper strips forms core as insulation screen 3 on insulating barrier 2.Fill filler 4 between insulated wire cores.The lapping layer 5 of being made by low smoke, zero halogen low-poison and combustion-resisting material at filler 4 peripheral wrapped one decks.At lapping layer 5 braiding proof copper-wire braided layers 6, extrude the oversheath 7 that one deck is made by low smoke, zero halogen low-poison and combustion-resisting cross-linked polyolefin material at proof copper-wire braided layer 6.
