Abstract
The invention discloses a fireproof cable for a ship. According to the fireproof cable for the ship, a conductor is formed by twisting multiple soft tinned copper wires, the conducted is wrapped in an insulating layer to form a cable core, three cable cores are twisted and then wrapped in two layers of mica tape to form a fireproof layer, the insulating layer is arranged on the fireproof layer in an extruding mode to form an insulating cable core, six insulating cable cores are combined and then are wrapped in two layers of mica tape to form a second fireproof layer, and an inner sheath layer, a tinned copper wire armor layer and an outer sheath layer are arranged outside the second fireproof layer in sequence, six insulating cable cores I are further arranged between the six insulating cable cores, and an insulating cable core II is arranged in the center of the cable. According to the fireproof cable for the ship, the excellent insulating property of the cable can still be maintained under the high-temperature combustion condition, and the cable can operate continuously in high-temperature flames.
Description
technical field
The present invention relates to a kind of marine fireproof 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.
summary of the invention
The invention provides a kind of marine fireproof cable and in high-temp combustion situation, still can keep good insulation property at cable, can operation continuously in thermal-flame.
The solution of the present invention is as follows: a kind of marine fireproof cable, conductor adopts the zinc-plated soft copper tow strand of multiply to form, on described conductor, wrapped irradiation crosslinked polyolefin insulating layer forms core, three stranded rear wrapped two-layer mica tape composition fireprotection layers of core, on described fireprotection layer, extrude irradiation crosslinked polyolefin insulating layer and form insulated wire cores, after the combination of six roots of sensation insulated wire cores, wrapped two-layer mica tape forms the second fireprotection layer, and the second described fireprotection layer sets gradually inner restrictive coating, tinned copper wire armour and external sheath layer outward; Between described six roots of sensation insulated wire cores, be also provided with six roots of sensation insulated wire cores I, described insulated wire cores I is made up of the wrapped irradiation crosslinked polyolefin insulating layer of conductor; Described cable center arranges insulated wire cores II, and described insulated wire cores II is made up of two rear wrapped irradiation crosslinked polyolefin insulating layers of core combination.
Further, described conductor is formed by the zinc-plated soft copper tow strand of 5-100 root, and described conductors cross is 0.5-120mm
2.
Further, described inner restrictive coating, external sheath layer all adopt thermoplasticity fire prevention polyolefin to make.
Oversheath all adopts the low cigarette polyolefin jacket of irradiation crosslinking halogen-free in cable of the present invention, has well the features such as fire-retardant, resistance to ozone, high mechanical properties; Oversheath outside extrudes one deck thermoplastic halogen-free fire prevention polyolefin jacket material, can effectively prevent the burning of flame, improves fireproofing of cable performance.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of marine fireproof cable, conductor 1 adopts the zinc-plated soft copper tow strand of multiply to form, on described conductor 1, wrapped irradiation crosslinked polyolefin insulating layer 2 forms core, three stranded rear wrapped two-layer mica tape composition fireprotection layers 3 of core, on described fireprotection layer 3, extrude irradiation crosslinked polyolefin insulating layer 4 and form insulated wire cores, after the combination of six roots of sensation insulated wire cores, wrapped two-layer mica tape forms the second fireprotection layer 5, described outer inner restrictive coating 6, tinned copper wire armour 7 and the external sheath layer 8 of setting gradually of the second fireprotection layer 5; Between described six roots of sensation insulated wire cores, be also provided with six roots of sensation insulated wire cores I 9, described insulated wire cores I 9 is made up of the wrapped irradiation crosslinked polyolefin insulating layer of conductor; Described cable center arranges insulated wire cores II 10, and described insulated wire cores II 10 is made up of two rear wrapped irradiation crosslinked polyolefin insulating layers of core combination.
Described conductor 1 is formed by the zinc-plated soft copper tow strand of 5-100 root, and described conductor 1 cross section is 0.5-120mm
2.Described inner restrictive coating 6, external sheath layer 8 all adopts thermoplasticity fire prevention polyolefin to make.
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 revise; 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.
