Abstract
The invention discloses a power cable for a ship. The power cable for the ship comprises conductors, cable cores, insulation wire cores and a sheath layer, wherein the cable cores are formed by combining six insulation wire cores; each insulation wire core is formed in a manner that a fireproof mica layer and a flame retardant belting layer are sequentially lapped the outside of three conductive cores; a fireproof mica layer II, a flame retardant coating, a double-layer flame retardant belting layer II and an outer sheath layer are sequentially lapped on the outside of the cable cores; the outer sheath layer is made of a halogen-free low-smoke flame retardant polyolefin material; six control wire cores are also arranged among the six insulation wire cores and are formed in a way that two conductive cores are pair-twisted and then are lapped by the flame retardant belting layer; the conductive cores are composed of extruding crosslinked polyethylene insulating layers outside the conductors; glass cords fill the gap between the cable cores and the fireproof mica layer II. By applying the power cable for the ship, when the cable catches fire, the flame can be effectively prevented to spread to the insulating layers, the flame retardant performance is good, and the burning retardant performance is achieved.
Description
technical field
The present invention relates to a kind of warship ship power cable, belong to technical field of electric wires and cables.
background technology
Along with the development of shipping industry, especially along with the development of large-tonnage ships technology, also more and more for the cable demand of boats and ships.Along with scientific and technical development, to requiring also more and more higher with the cable of marine equipment.Conventionally flame retardant cable used is substantially all to adopt flame retardant insulation material, fire-retardant band, flame-retardant filler, flame-retardant sheath material.Its deficiency is: in the time of breaking out of fire, cable stops the performance of propagation of flame not strong, and flame easily spreads to insulating barrier.Boats and ships and personnel's safety is caused to very large hidden danger.For shipboard cable, fire resistance requires very high, and the cable of ordinary construction, in the time of ignition of cable, can not effectively stop spreading of flame.
summary of the invention
The object of the present invention is to provide a kind of warship ship power cable, in the time of ignition of cable, can effectively stop flame to spread to insulating barrier, fire resistance be good, and has stagnant right property.
The solution of the present invention is as follows: a kind of warship ship power cable, comprise conductor, core, insulated wire cores and restrictive coating, described cable core is combined by six roots of sensation insulated wire cores, and described insulated wire cores is led core by three, and wrapped fireproof mica layer, fire-retardant belting layer form successively outward; The outer wrapped fireproof mica layer II successively of described cable core, flame retardant coating, double-deck fire-retardant belting layer II and the external sheath layer that adopts halogen-free and low-smoke flame-retardant polyolefin material to make; Between described six roots of sensation insulated wire cores, be also provided with six roots of sensation control core, after described control core is led core pair twist by two, wrapped fire-retardant belting layer forms; The described core of leading extrudes crosslinked polyetylene insulated layer outward by conductor and forms; Between described cable core and fireproof mica layer II, be filled with glass cord.
Further, described conductor structure meets the requirement of the 5th kind of conductor in GB/T 3956, by stranded the forming of 5-80 thigh silver-gilt copper wire.
Further, described thickness of insulating layer is 0.06-0.1mm.
The present invention arranges one deck flame retardant coating, and this coating can improve self-extinguishment, hydrophobicity, sealing, insulating properties of cable etc., and this coating self adhesive force is good, fineness is good.Lead core and cable core fire-resistant female layer that goes is all set outward, can make cable there is better flame retardant effect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
embodiment
A kind of warship ship power cable, comprises conductor, core, insulated wire cores and restrictive coating, and described cable core is combined by six roots of sensation insulated wire cores, and described insulated wire cores is led core by three, and wrapped fireproof mica layer 3, fire-retardant belting layer 4 form successively outward; The outer wrapped fireproof mica layer II 5 successively of described cable core, flame retardant coating 6, double-deck fire-retardant belting layer II 7 and the external sheath layer 8 that adopts halogen-free and low-smoke flame-retardant polyolefin material to make; Between described six roots of sensation insulated wire cores, be also provided with six roots of sensation control core 9, after described control core is led core pair twist by two, wrapped fire-retardant belting layer forms; The described core of leading forms by extruding crosslinked polyetylene insulated layer 2 outside conductor 1; Between described cable core and fireproof mica layer II, be filled with glass cord.
Described conductor 1 structure meets the requirement of the 5th kind of conductor in GB/T 3956, by stranded the forming of 5-80 thigh silver-gilt copper wire.Described insulating barrier 2 thickness are 0.06-0.1mm.
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 and accompanying drawing contain yet, all should be within protection scope of the present invention.
