Abstract
The utility model discloses a mobile light-weight halogen-free flame-retardant flexible cable for a vessel. The flexible cable adopts the structure that a plurality of insulated cores are stranded to form a cable core, and filler yarns are filled in the gap of the cable core; a polyester belt and a fire resistant belt are wrapped outside the cable core; an armor layer is arranged outside the fire resistant belt; an outer sheath is extruded outside the outermost layer of the cable; and each insulated core comprises a conductor, as well as an inner insulation layer and an outer insulation layer which are extruded outside the conductor. According to the utility model, the current bearing capacity of the conductor is improved with the improvement of the operating temperature, or both the external diameter and the weight of the cable are further reduced through reducing the conductor cross section under the condition of the same current bearing capacity, therefore the flexible cable provided by the utility model has the characteristics of small external diameter, light weight, good electrical performance and mechanical property, and the like.
Description
Technical field:
The utility model relates to a kind of naval vessel with moving light-duty halogen-free flameproof flexible cable.
Background technology:
All with reference to the relevant shipboard cable standard of IEC, its external diameter bound scope is big, and does not stipulate the upper weight limit of cable with its insulation thickness of cable and parameters such as the outside diameter of cable on common naval vessel.For more effectively usage space and payload capability are provided in the confined space on naval vessel, adopt the naval vessel can reach above purpose with mobile lightweight cable.
Summary of the invention:
For overcoming the defective of prior art; The purpose of the utility model is to provide a kind of naval vessel with moving light-duty halogen-free flameproof flexible cable; Through improving the conductor working temperature to improve its ampacity; Or under identical ampacity, reduce external diameter and the weight of cross-sectional area of conductor further to reduce cable, this naval vessel with mobile lightweight cable have that external diameter is little, in light weight, characteristic such as electric property and good mechanical property.
The utility model technical solution problem adopts following technical scheme:
A kind of naval vessel is with moving light-duty halogen-free flameproof flexible cable, and many insulated core is twisted into cable core, and the cable core gap is provided with gasket for packing, outside said cable core, is surrounded with polyester belt and inhibiting tape, and said inhibiting tape is provided with armour outward, and the outermost layer of cable is extruded with oversheath; Said insulated wire cores is made up of conductor and the inner insulating layer and the external insulation layer that extrude on conductor.
The design feature of the utility model also is:
Said inner insulating layer, external insulation layer are the low-smoke non-halogen flame-retardant cross-linked polyolefin insulating barrier of 125 ℃ of levels.
Said armour is an aluminum-alloy wire braiding armour.
Said oversheath is the crosslinking type low-smoke halogen-free flame-retardant sheath of 125 ℃ of levels.
Compared with present technology, the beneficial effect of the utility model is embodied in:
The utility model is brought up to 125 ℃ with the working temperature of cable by 85 ℃ of common shipboard cable, can under the same conductor cross section, improve its ampacity, or the cross-sectional area of conductor that under identical ampacity, reduces cable is to reduce the outside diameter of cable and cable weight; Insulation thickness reduces than common shipboard cable when satisfying electric property and mechanical performance and not descending, and its total insulation thickness is 75% to 85% of a same specification common cable insulation thickness; Replace the extrude inner covering of common armouring type ship with double-layer polyester band (thickness 0.05mm) and one deck halogen-free flameproof band (thickness 0.08mm), in the protection cable core, further reduce the external diameter and the weight of cable with cable; With the density 2.7g/cm that only has an appointment
3The high-strength aluminum alloy silk replace common ship armature of cable material (density be about 8.9g/cm
3Tinned copper wire or density be about 7.8g/cm
3Zinc-coated wire), further reduce the weight of cable; Oversheath is the crosslinking type low-smoke halogen-free flame-retardant sheath of 125 ℃ of levels, and its thickness confirms that with reference to common shipboard cable THICKNESS CALCULATION method because of the cable external diameter reduces, the cable cover(ing) weight also common shipboard cable than same specification is little.
Selecting for use of these structure and materials guarantees that the naval vessel can provide more effectively usage space and payload capability with moving lightweight cable in the confined space on naval vessel.
Description of drawings:
Fig. 1 is the cross section structure sketch map of the utility model cable.
Label among the figure: 1 conductor, 2 inner insulating layers, 3 external insulation layers, 4 polyester belts, 5 inhibiting tapes, 6 armours, 7 oversheaths, 8 gasket for packings.
Below pass through embodiment, and combine accompanying drawing that the utility model is described further.
Embodiment:
Embodiment: combine Fig. 1; Present embodiment is example with the quad; The insulated core is stranded forms by four for cable conductor, each insulated wire cores by tin-coated copper conductor 1 with coat it and go up and the inner insulating layer 2 that reduced by 125 ℃ of levels of thickness is formed with external insulation layer 3, double-deck low-smoke non-halogen flame-retardant cross-linked polyolefin to conductor formation insulate; Be provided with LSOH anti-flaming gasket for packing 8 in the cable core gap; Outside cable core, be surrounded with double-layer polyester band 4 (thickness is 0.05mm) and one deck halogen-free flameproof band 5 (thickness 0.08mm), be provided with layer of aluminum alloy silk braiding armour 6 outward, outside armour, be extruded with the crosslinking type low-smoke halogen-free flame-retardant oversheath 7 of 125 ℃ of levels.
In specifically being provided with, conductor is the tin-coated copper conductor of stranded soft or special soft junction structure; Insulating barrier is the double-deck low-smoke non-halogen flame-retardant cross-linked polyolefin insulation of 125 ℃ of levels, and insulation thickness is 75% to 85% of a same specification common cable insulation thickness; Be filled to the LSOH anti-flaming gasket for packing; Band is double-layer polyester band (thickness is 0.05mm) and one deck halogen-free flameproof band (thickness 0.08mm); Armour is high-strength aluminum alloy silk braiding armouring; Oversheath is the crosslinking type low-smoke halogen-free flame-retardant sheath of 125 ℃ of levels.
Except that the foregoing description, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
