Abstract
The utility model discloses a marine shielded cable. Conductors are twisted by multistrand tinned copper wires, each conductor is extruded with a cross-linked polyolefin insulating layer to form an insulated wire core, three insulated wire cores are combined and then wrapped with a metal shielding layer to form a conductive core, six conductive cores are combined and then wrapped with a polyurethane belt layer, the polyurethane belt layer is wrapped with a tinned copper wire shielding layer, and an inner sheath layer, a braided armoured layer and an outer sheath layer are sequentially arranged outside the tinned copper wire shielding layer; and six control wire cores are arranged between the six conductive cores. The marine shielded cable is light in weight, convenient in laying, has good flame retardant performance and excellent aging resistance, has low capacitance and low inductance, and has good shielding performance and anti-interference performance.
Description
technical field
The utility model relates to a kind of shielded type cable peculiar to vessel, belongs to technical field of electric wires and cables.
background technology
Shipboard cable in use, is laid in open deck, bathroom, freight house, refrigerated compartment, cabin and may has the places such as water accumulation steam or harmful steam.Because the space that shipboard cable lays is narrower and small, be difficult for laying, cable weight is heavier, gives to lay and has brought very inconvenience.
utility model content
The utility model provides a kind of simple in structure, lightweight, shielded type cable peculiar to vessel that volume is little.
Scheme of the present utility model is as follows: a kind of shielded type cable peculiar to vessel, conductor is stranded with multiply tinned wird, on described conductor, extrude cross-linked polyolefin insulating barrier and form insulated wire cores, after three insulated wire cores combinations, wrapped metal screen layer formation is led core, the six roots of sensation is led the rear wrapped polyurethane belting layer of core combination, the outer wrapped tinned copper wire screen of described polyurethane belting layer, described tinned copper wire screen sets gradually inner restrictive coating, braiding armour, external sheath layer outward; The described six roots of sensation is led between core group six roots of sensation control core is also set, and described control core is made up of the wrapped metal screen layer of pair twist group, and described pair twist group is made up of the core of the outer wrapped polyolefin insulation layer of two conductors.
Further, under described screen, be also provided with a bare copper conductor drainage thread.
Further, described inner restrictive coating and external sheath layer all adopt and extrude cross-linking radiation polyolefine material and extrude.
Further, described armour adopts almag wire material to make.
The utility model cable has low electric capacity and low inductance, has good shielding properties and interference free performance, has improved greatly the shielding properties of cable, has good anti-external electromagnetic field and disturbs and do not produce external interference.Interior oversheath all adopts cross-linking radiation polyolefin, has improved the temperature resistant grade of cable, and the fire resistance of cable is good, and resistance to ag(e)ing is good, has also improved the mechanical performance of cable simultaneously.
brief description of the drawings
Fig. 1 is structural representation of the present utility model.
embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of shielded type cable peculiar to vessel, conductor is stranded with multiply tinned wird, on described conductor 1, extrude cross-linked polyolefin insulating barrier 2 and form insulated wire cores, after three insulated wire cores combinations, wrapped metal screen layer 3 formations are led core, the six roots of sensation is led the rear wrapped polyurethane belting layer 4 of core combination, the outer wrapped tinned copper wire screen 5 of described polyurethane belting layer 4, outer inner restrictive coating 6, braiding armour 7, the external sheath layer 8 of setting gradually of described tinned copper wire screen 5; The described six roots of sensation is led between core group six roots of sensation control core 9 is also set, and described control core is made up of the wrapped metal screen layer of pair twist group, and described pair twist group is made up of the core of the outer wrapped polyolefin insulation layer of two conductors.
Under described screen, be also provided with a bare copper conductor drainage thread 10.Described inner restrictive coating and external sheath layer all adopt and extrude cross-linking radiation polyolefine material and extrude.Described armour adopts almag wire material to make.
Although above embodiment of the present utility model 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 utility model and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
