Specific embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in Figure 1：Fire safe type ship LAN cable of warship described in the utility model include cable core, cable core it is centrally disposed
Cross insulation framework 3, four gap locations that insulation framework 3 is separated into are respectively provided with four groups of pair twist cores, pair twist core and absolutely
In the wrapped polyester belt 8 of outer layer after edge skeleton 3 is stranded, channelizing line 1 is set in the outside of polyester belt 8, and in polyester belt 8 and channelizing line

Tin copper wire split screen layer 6.
In the centrally disposed high intensity aramid yarn 2 of the insulation framework 3.
The operation principle of fire safe type ship LAN cable of warship described in the utility model：
1st, tensile property is improved：
The centrally disposed cross insulation framework of LAN cable, its effect is for supporting cable conductor, it is ensured that electricity
Cable roundness, while also separate each group core, it is convenient to install.
Cross insulation framework by extruded outside an aramid yarn cross insulation be made, cross sets in gap
Four groups of pair twist cores are put, because four groups of pair twist cores are stranded, twisted pair wire around cross insulation framework in finished cable
Physical length after core launches is more long than the length of cross insulation framework, therefore during dragging, main stress point is concentrated on
On cruciform skeleton, cable pair twist core is protected.
2nd, solve the problems, such as internal cross-talk and improve electromagnetic interference performance：
The shielding of the pair twist core of cable is to weave tin-coated copper outside each core using in " split screen+total screen " structure, i.e. cable
Braiding split screen, count is 90%, and one layer of pair twist split screen is woven outside pair twist core, and count is 90%, and this Rotating fields can
Other cores are not disturbed with the electromagnetic wave for each core of cable is produced, cross-talk between each core is solved the problems, such as；Exist in addition
There are two-layer shielding construction, i.e. aluminium foil strip and metal knitted total screen outside cable core, this double-layer structure can prevent external electromagnetic interference from entering
Enter inside cable, strengthen the anti-electromagnetic interference capability of cable.
3rd, the fire resistance of cable is improved：
In cable conductor, one layer of two-sided calcining mica tape is provided with outside sheath, be provided with outer jacket one layer of Halogen band+
One layer of two-sided calcining mica tape, when the outer jacket or sheath of cable are damaged in a fire, two-sided calcining mica tape can be with
Effective to prevent fire from entering cable, the cable has two-layer flame retardant coating, therefore the fire resistance of cable is improved.
