As preferably, described insulation screen is a semiconductive ethylene-propylene rubber.
As preferably, described in lapping layer and outer lapping layer be the Halogen band.
As preferably, described inner metal shield layer and outer metal screen layer weave by copper wire and form, and count 〉=88%.
As preferably, described inner restrictive coating and external sheath layer are the non-halogen flame-proof cross-linking polyolefin.
Compared with prior art, advantage of the present utility model is: intensity height, flexibility are good, safe in utilization, reliable, the low-smoke non-halogen flame-retardant performance is good, produce secondary disaster in the time of effectively avoiding cable fire, and can be implemented in particular field in one's power the electric equipment of small space connect with cable, and easy for installation, be easy to safeguard.
The electrical equipment that it is suitable for various boats and ships connects electrical apparatus control equipment with special places such as cable and chemical industry, the intensive venue of personnel and skyscrapers and is connected and uses cable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of soft low-smoke halogen-free shipboard cable, comprise cable core and be wrapped in the outer sheath 2 of cable core, described cable core is made up of 5～60 heart yearns 1, each root heart yearn 1 is five layers of composite construction, is followed successively by conductor thread core 11, insulating barrier 12, insulation screen 13, interior lapping layer 14, inner metal shield layer 15 from inside to outside; Described sheath 2 is five layers of composite construction, is followed successively by outer lapping layer 21, inner restrictive coating 22, flame-retardant mica belt 23, outer metal screen layer 24, external sheath layer 25 from inside to outside.
In the present embodiment, described heart yearn 1 is 5, and twists together.Gap in the described sheath 2 is provided with packing, and this packing is fire-retardant rubber packing.Described conductor thread core 11 is 6～20 strands of stranded zinc-plated soft copper silks, and the diameter of this zinc-plated soft copper silk is 0.1～0.7 millimeter, adopts 9 zinc-plated soft copper skein silks to close in the present embodiment and forms.Described insulating barrier 12 is through the ethylene propylene rubber insulated layer of the high-modulus halogen-free flameproof that extrudes formation.Described insulation screen 13 is through the ethylene propylene rubber insulated screen of the semiconductive that extrudes formation.Lapping layer 14 and outer lapping layer 21 are the low smoke and zero halogen band lapping layer through wrapped formation in described.Described inner metal shield layer 15 and outer metal screen layer 24 form by the copper wire braiding, and count 〉=88%.Described inner restrictive coating 22 and external sheath layer 25 all are to be provided with in the mode that extrudes the low-smoke non-halogen flame-retardant cross-linked polyolefin.Described flame-retardant mica belt 23 is through wrapped formation, plays oxygen barrier, fire-retardant, fire-resistant effect.
