Abstract
The utility model discloses a power cable for concentric conductor ship belonging to the technical field of the cable, comprising three-ply electrical conduction cores arranged in the center, and the outer of each core is provided with insulation layer homogeneously. The three-ply electrical conduction cores are twined in a bundle, and the outer of the twined bundle of the electrical conduction cores is provided with an inner enwrapping layer. A filling layer is arranged between the inner enwrapping layer and the electrical conduction cores, and an inner sheath is arranged outside the inner enwrapping layer. A component wire conductor layer is arranged outside the inner sheath, and the component wire conductor layer comprises a plurality of unidiameter component wire conductors arranged around the circumference homogeneously. The outer of component wire conductor layer is provided with an outer enwrapping layer, and the outer of the outer enwrapping layer is provided with an outer sheath. The utility model has favorable shielding action, which can resist the electromagnetic interference and the lightning stroke. In addition, the lower and homogeneous positive sequence, negative sequence and null sequence working impedance and the low reactance value of the neutral line in the operating state are propitious to the sensitive action of the short circuit automatic safety device, so the safe operation of the corresponding device of the cable can be ensured. The utility model especially adapts to be used as the power cable for ship.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of ship power cable.
Background technology
Ship power cable of the prior art, the per share outer four strands of conductor wire cores that are equipped with insulating barrier that comprise the center of being arranged at, four strands of stranded bunchys of conductor wire core, outside the conductor wire core of stranded bunchy, be provided with interior lapping layer, be provided with packed layer between interior lapping layer and the conductor wire core, interior lapping layer is provided with inner sheath outward, and inner sheath is provided with outer lapping layer outward, and outer lapping layer is provided with oversheath outward.This cable is that 3+1 arranges that during use, four strands of conductor wire cores are connected triple line and center line respectively; Its weak point is: the reactance value height of center line under in working order, the anti-electromagnetic interference capability of cable is poor.
The utility model content
The purpose of this utility model provides a kind of concentric conductor ship power cable, and the reactance value of the center line that makes cable under in working order is low, and the anti-electromagnetic interference capability of cable is strong, and power supply quality is good.
The purpose of this utility model is achieved in that a kind of concentric conductor ship power cable, the per share outer three strands of conductor wire cores that are equipped with insulating barrier that comprise the center of being arranged at, three strands of stranded bunchys of conductor wire core, outside the conductor wire core of stranded bunchy, be provided with interior lapping layer, be provided with packed layer between interior lapping layer and the conductor wire core, interior lapping layer is provided with inner sheath outward, inner sheath is provided with the cored wire conductor layer outward, described cored wire conductor layer is along the circumferential direction evenly arranged by some isometrical cored wire conductors and is formed, the cored wire conductor layer is provided with lapping layer outward, and lapping layer is provided with oversheath outward.
When the utility model uses; three strands of conductor wire cores at center connect the triple line of power supply; the cored wire conductor layer is connect center line; because cored wire conductor is along the circumferential direction evenly arranged; therefore; itself can constitute a screen; make cable have good shielding action; can anti-electromagnetic interference be struck by lightning with anti-; in addition, this design make product have lower and uniformly just, backward and zero sequence working impedance, the reactance value of center line under in working order is low; help the sensitivity action of short circuit automatic safety device, thereby guarantee the safe operation of cable relevant device.The utility model is particularly suitable as the marine vessel power cable and uses.
Description of drawings
Fig. 1 is this practical section structure schematic diagram.
Wherein, 1 oversheath, 2 outer lapping layers, 3 cored wire conductors, 4 inner sheaths, 5 interior lapping layers, 6 insulating barriers, 7 conductor wire cores, 8 packed layers.
Embodiment
As figure, be a kind of concentric conductor ship power cable, the per share outer three strands of conductor wire cores 7 that are equipped with insulating barrier 6 that comprise the center of being arranged at, three strands of stranded bunchys of conductor wire core, lapping layer 5 in outside the conductor wire core of stranded bunchy, being provided with, be provided with packed layer 8 between interior lapping layer 5 and the conductor wire core, the interior lapping layer 5 outer inner sheaths 4 that are provided with, the inner sheath 4 outer cored wire conductor layers that are provided with, described cored wire conductor layer is along the circumferential direction evenly arranged by some isometrical cored wire conductors 3 and is formed, the cored wire conductor layer is provided with outer lapping layer 2 outward, the outer lapping layer 2 outer oversheaths 1 that are provided with.
