Abstract
The utility model discloses a low-smoke halogen-free electric cable for a high temperature resistant ship, which comprises a high temperature resistant insulating layer which is arranged on the outer portion of a twisted tin-plated copper conductor to form insulating wire cores, a plurality of pairs of insulating wire cores and a plurality of solid core fill cores are twisted to form cables, the outer portions of the twisted cables are added with warping tapes, and the outer layer of the warping tapes are provided with a lining and an outer protection sleeve. The utility model discloses an electric cable, and greatly increases the current-carrying capacity of cables with the same conductor sections through changing the insulating materials of electric cables for traditional ships. The temperature resistant grade of the electric cable is increased to 150 DEG C. The outer protection sleeve of the electric cable with thermosetting property increases the mechanical property of the electric cables.
Description
Technical field
The utility model relates to the cables manufacturing technical field, particularly relates to a kind of high temperature resistant naval vessel low-smoke halogen-free cable.
Background technology
Along with the development of shipping industry, China has become the third-largest shipbuilding state in the world, and the demand of shipboard cable also increases greatly.The naval vessel can be divided into three major types with cable, and warship ship power cable, naval vessel are with control cable, naval vessel communication cable.Wherein, the warship ship power cable is used for the usefulness of electric power, illumination and the general control of aquatic buildings such as river various boats and ships in sea and offshore drilling platforms.Along with the user to the improving constantly of ship power performance, handling and security requirement, the naval vessel not only will satisfy the requirement of the fire-retardant category-A grade of low smoke and zero halogen bunchy with cable, and for the temperature resistant grade of cable higher requirement has been arranged also.
The utility model content
In view of this, the purpose of this utility model provides a kind of high temperature resistant naval vessel low-smoke halogen-free cable, and the material temperature resistant grade of employing is 150 ℃, has satisfied client's demand, has improved the ampacity of cable.The oversheath of cable and lining adopt heat cured low-smoke halogen-free polyolefin, have strengthened the mechanical performance of cable.
Be a kind of high temperature resistant naval vessel low-smoke halogen-free cable of realizing that the purpose of this utility model provides, temperature-resistant insulation layer is set outside the stranded tin-coated copper conductor of cable forms insulated wire cores, some insulated wire cores is filled out the stranded stranding of core with some real cores, the cable that is twisted into adds twining package tape, at the skin of twining package tape lining and oversheath is set.
The armour of braided steel wire is set between described lining and the sheath.
Described temperature-resistant insulation layer is to adopt 150 ℃ high temperature resistant low-smoke halogen-free polyolefin material.
Described lining is the low-smoke halogen-free polyolefin lining of thermosetting.
The oversheath that described armour is extruded outward again is the low-smoke halogen-free polyolefin sheath of thermosetting.
The beneficial effects of the utility model are: compared with prior art, the utility model is by changing the insulating material of conventional ship with cable, adopt a kind of 150 ℃ high temperature resistant low-smoke halogen-free polyolefin material as insulator, remedied the conductor temperature resistant grade lower defective of plain edition naval vessel with cable, improved the long-term permission working temperature of cable conductor, and under the condition that guarantees its electric property, improved the ampacity of cable conductor greatly, thereby make that the cross section of the cable conductor under the identical ampacity requirement reduces greatly in the circuit, and satisfied the low smoke and zero halogen performance requirement of cable.The oversheath of cable and lining adopt heat cured low-smoke halogen-free polyolefin, have strengthened the mechanical performance of cable.
Description of drawings
A kind of high temperature resistant naval vessel that Fig. 1 provides for the utility model structural representation of low-smoke halogen-free cable.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1, a kind of high temperature resistant naval vessel low-smoke halogen-free cable that provides, comprise: outside copper conductor (1), extrude one deck insulating material (2), then, some insulated wire cores is filled out the stranded stranding of core (4) with some real cores, the cable that is twisted into adds twining package tape (3), extrudes lining (5) at the skin of twining package tape, lining is composed of armour (6) outward, and armour is extruded oversheath (7) outward again.
In the utility model, on the specific implementation, copper conductor (1) is stranded tin-coated copper conductor.
In the utility model, on the specific implementation, the outer insulating material of extruding (2) of described copper conductor (1) is the high temperature resistant low-smoke halogen-free polyolefin insulating barrier of 150 ℃ of one decks.
In the utility model, on the specific implementation, the lining of extruding at the skin of twining package tape (3) (5) is the low-smoke halogen-free polyolefin lining of thermosetting.
In the utility model, on the specific implementation, the armour (6) of lining outer (5) is the armour of braided steel wire.
In the utility model, on the specific implementation, the outer oversheath of extruding again (7) of armour (6) is the low-smoke halogen-free polyolefin sheath of thermosetting.
An instantiation:
For requiring voltage in the circuit is that 380V, electric current are the 4 core cables of 14A, is 60 ℃ pvc material if adopt conductor to allow working temperature for a long time, needs to adopt cross-sectional area of conductor be at least 4mm
2If adopting this conductor to allow working temperature for a long time is 150 ℃ material, the cross-sectional area of conductor that needs to adopt is 1.5mm
2Get final product,, alleviated the weight of cable greatly, reduced the cost of cable, make the work of laying of cable be more prone to because reducing of cross-sectional area of conductor makes the external diameter of finished cable reduce greatly.
In sum, compared with prior art, a kind of high temperature resistant naval vessel low-smoke halogen-free cable that the utility model provides, adopt a kind of 150 ℃ high temperature resistant low-smoke halogen-free polyolefin material as insulator, remedied the conductor temperature resistant grade lower defective of plain edition naval vessel with cable, improved the long-term permission working temperature of cable conductor, and under the condition that guarantees its electric property, improved the ampacity of cable conductor greatly, thereby make that the cross section of the cable conductor under the identical ampacity requirement reduces greatly in the circuit, and satisfied the low smoke and zero halogen performance requirement of cable.The oversheath of cable and lining adopt heat cured low-smoke halogen-free polyolefin, have strengthened the mechanical performance of cable.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
