Abstract
The invention discloses a flame-retardant tensile degaussing cable. The flame-retardant tensile degaussing cable is composed of a power cable core, a tinned copper braid shielding layer, a steel wire armoring layer and a crosslinking polyolefin outer protection sleeve. The power cable core is formed by squeezing and packaging five fan-shaped tinned copper wire alloy conductors through aluminum-plastic composite taped coverings. A tension-resistant steel wire coated with a silicon rubber insulating layer is coaxially arranged in the power cable core. The power cable core is provided with the tinned copper braid shielding layer, the steel wire armoring layer and the crosslinking polyolefin outer protection sleeve from inside to outside in sequence. A ground wire cable core is arranged between the tinned copper braid shielding layer and the steel wire armoring layer. The flame-retardant tensile degaussing cable is good in conductivity, tensile resistance performance, electromagnetic shielding performance, insulating property and anti-aging performance, large in current-carrying capacity and strong in overload protection performance.
Description
Technical field
The present invention relates to cable, relate in particular to a kind of demagnetization flame-retardant pull tension cable.
Background technology
Naval vessel especially under water naval vessel in navigation process because of stealthy importance, to prevent especially magnetic mine attack, need often to carry out hull demagnetization for this reason.Because the particularity of ship navigation environment and complexity under water; common degaussing cable cannot meet the required demagnetization performance of the outer installation of ship side simultaneously; and the tensile property of cable also requires very high; can play good tension protective effect to cable inner conductor, thereby the tensile property and the demagnetization performance that how to improve inner conductor in cable are those skilled in the art's technical problems in the urgent need to address.
Summary of the invention
According to above-mentioned situation, the object of the invention is to provide a kind of demagnetization flame-retardant pull tension cable.
The solution of the present invention is as follows: a kind of demagnetization flame-retardant pull tension cable, it is made up of power core, tinned copper wire woven shield, wire armoring layer and cross-linked polyolefin oversheath, and described power core is to extrude five fan-shaped silver-gilt copper wire alloy conductors by plastic-aluminum combined lapping layer to form; Described power line core inner arranges a tension steel wire being coated by silicone rubber insulation layer with one heart; Described power core is from inside to outside disposed with tinned copper wire woven shield, wire armoring layer and cross-linked polyolefin oversheath; Between described tinned copper wire woven shield and wire armoring layer, be provided with a ground wire core.
Beneficial effect of the present invention: the present invention has improved the electric conductivity of product, and tension is effective, has good capability of electromagnetic shielding, insulation property and ageing-resistant performance, and ampacity is large, and overload protection performance is strong.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Wherein: 1, cross-linked polyolefin oversheath; 2, wire armoring layer; 3, tinned copper wire woven shield; 4, silver-gilt copper wire alloy conductor; 5, wire core; 6, silicone rubber insulation layer; 7, tension steel wire; 8, plastic-aluminum combined lapping layer.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of demagnetization flame-retardant pull tension cable, it is made up of power core, tinned copper wire woven shield 3, wire armoring layer 2 and cross-linked polyolefin oversheath 1, and described power core is to extrude five fan-shaped silver-gilt copper wire alloy conductors 4 by plastic-aluminum combined lapping layer 8 to form; Described power line core inner arranges a tension steel wire 7 being coated by silicone rubber insulation layer 6 with one heart; Described power core is from inside to outside disposed with tinned copper wire woven shield 3, wire armoring layer 2 and cross-linked polyolefin oversheath 1; Between described tinned copper wire woven shield 3 and wire armoring layer 2, be provided with a ground wire core 5.
The present invention adopts silver-gilt copper wire alloy conductor 4 to improve the electric conductivity of product, tension steel wire 7 plays good drawing-resistant function to cable, effectively prevented that cable from neutralizing in laying construction process that other factors cause pull, tensile phenomenon; Tinned copper wire woven shield 3 outside power core has good capability of electromagnetic shielding; Adopt cross-linked polyolefin oversheath 1, make product have electric, insulation property and ageing-resistant performance preferably, ampacity is large; overload protection performance is stronger, compared with common demagnetization control cables, has excellent fire resistance and environmental-protecting performance; shield effectiveness is good, and electric property is stable.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and amendment; when its function producing does not exceed spiritual that specification contains yet, all should be within protection scope of the present invention.
