Abstract
The utility model discloses a flame-proof high-temperature resistant ship-used power cable. The power cable comprises four alloy conductors respectively coated with a refractory layer and an insulation layer in sequence; the four alloy conductors coated with the insulation layer surround a filling rope, and are twisted into a bundle; a fire-proof layer is coated on the filling rope; the fire-proof layer is wrapped by a double-layer synthetic mica tape, the wrapping coverage rate is not smaller than 30 percent; the bunchy alloy conductors are coated with a belting layer, an inner sheath layer, an armor layer and an outer sheath layer in sequence, the armor layer is knitted by tinned copper wires, and the knitting tightness is not smaller than 86 percent. The utility model has a novel structure, the filling rope surrounded by the alloy conductors is coated with the fire-proof layer, thus the fire-proof characteristic of the cable is improved by adopting the double-layer synthetic mica tape for overlapped wrapping; besides, excellent mechanical strength of the cable ensures the stability of the signal transmission.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to the high temperature resistant ship power cable of a kind of flame retardant type.
Background technology:
Fire-resisting cable as its name suggests; Be meant under certain flame temperature burning condition; Cable within a certain period of time the normal transmission electric energy, transmit various control signals, alarm signal; Make illumination, fireproof alarming device and other emergency sets can in fixing time, continue energising, make rescue work be able to normally carry out.Because fire-resisting cable has excellent flame-retardant performance, in fire-fighting, plays an important role, and receives users' welcome deeply.
Cable is made up of conductor, insulating barrier and restrictive coating, is the electric product that is used for electric energy transmitting, transmission information and realizes the electromagnetic energy conversion.Cable is widely used in during the daily life of electric power system, colliery, industrial and agricultural production and people draws together; It can safe operation under certain condition of work; But when it will cause that the insulating material insulation resistance descends, loses insulating capacity even burning and then initiation fire explosion accident under heat effect outside malfunctions such as overload short circuit, local overheating reach.
In recent years, the construction scale of each colliery, factory, building and equipment is increasing, and required thereupon cable is also increasing.Because cable is taked to concentrate the mode of laying usually, in case breaking out of fire, flame can spread along cable passage, and fire is enlarged rapidly.Simultaneously, the toxicity of seondary effect that fire brings such as personnel's injures and deaths, combustion fumes and to the pollution of environment etc. causes the loss more great than fire itself sometimes.Therefore, for the attention that more and more causes countries in the world of selecting for use of low smoke and zero halogen fire-resisting cable.
The fire performance of original flame retardant type cable self is relatively poor relatively, can not satisfy the demand of actual working environment, causes signal transmission instability in the course of the work, even interrupts, and has had a strong impact on production, causes great loss.
The utility model content:
To the problem that prior art exists, the purpose of the utility model provides the high temperature resistant ship power cable of a kind of flame retardant type, has solved the relatively poor relatively defective of the flame-retarding characteristic of shipboard cable in the operational environment of reality, has guaranteed the stability of signal transmission.
The utility model technical scheme following:
The high temperature resistant ship power cable of flame retardant type comprises four alloy conductors, it is characterized in that: four alloy conductors are enclosed with flame retardant coating, insulating barrier outward successively respectively; Four conductors of wrap insulate layer are the stranded bunchy in center around gasket for packing, and gasket for packing is wrapped with fireprotection layer, and fireprotection layer adopts the wrapped formation of double-deck synthetic mica tape; Wrapped coverage rate is not less than 30%; The outside is enclosed with belting layer, inner restrictive coating, armour, external sheath layer successively respectively behind the bunchy.
The high temperature resistant ship power cable of described flame retardant type is characterized in that: described armour adopts the tinned copper wire braiding to constitute, and count is not less than 86%.
The utility model has the advantages that:
The utility model novel structure, the gasket for packing at the conductor center is wrapped with fireprotection layer, adopts double-deck mica tape overlapping wrapped; Improved the fireproofing of cable characteristic; In addition, cable also has excellent mechanical intensity, has fully guaranteed the stability of the signal transmission of cable.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
The high temperature resistant ship power cable of flame retardant type comprises 1, four alloy conductor of four alloy conductors, 1 outer flame retardant coating 2, the insulating barrier 3 of being enclosed with respectively successively; Four conductors 1 of wrap insulate layer 3 are the stranded bunchy in center around gasket for packing 4, and gasket for packing 4 is wrapped with fireprotection layer 5, and fireprotection layer 5 adopts the wrapped formation of double-deck synthetic mica tape; Wrapped coverage rate is not less than 30%; Improved fireproofing of cable characteristic while cable and also had excellent mechanical intensity, fully guaranteed the stability of the signal transmission of cable, the outside is enclosed with belting layer 6 successively respectively behind the bunchy; Inner restrictive coating 7, armour 8; External sheath layer 9, armour 9 adopt the tinned copper wire braiding to constitute, and count is not less than 86%.
Claims (2)
