Abstract
The invention discloses a light shielding control and instrument cable for a ship. Each conductor is formed by multiple strands of tinned wires in a twisted mode. Each polyolefin insulating layer is arranged on one conductor in an extruding wrapping and cross bonding mode so that an insulated wire core can be formed. Every two pairs of insulated wire cores are twisted together as one unit and coated with polyester tape in a wrapped mode and an aluminum plastic composite tape shielding layer is further arranged on the polyester tape so that a shielding unit can be formed; the multiple shielding units and flame retarding filling ropes are twisted together so that a cable core can be formed; a flame retarding wrapping tape taped covering layer, an inner protecting sleeve layer, a knitted armor layer and an outer protecting sleeve layer are respectively arranged on the cable core from inside to outside. The light shielding control and instrument cable for the ship is light in weight, convenient to lay, good in flame retarding performance and anti-aging performance, low in capacitance and inductance and good in shielding performance and anti-interference performance.
Description
Technical field
The present invention relates to a kind of instrument cable, relate in particular to a kind of marine light shielding and control and instrument cable, belong 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 the places such as water accumulation steam or harmful steam may be arranged.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.
Summary of the invention
The invention provides a kind of marine light shielding simple in structure, lightweight, that volume is little controls and instrument cable.
The solution of the present invention is as follows: a kind of marine light shielding is controlled and instrument cable, its conductor is stranded with the multiply tinned wird, extrude the cross-linked polyolefin insulating barrier and form insulated wire cores on described conductor, every two pairs of insulated wire cores twist together and wrapped polyester belt with a unit, on polyester belt, also have the aluminium-plastic tape screen to form a screen unit; A plurality of screen units are stranded formation cable core together with fire-retardant gasket for packing; Be respectively equipped with from inside to outside fire-retardant band lapping layer, inner restrictive coating, braiding armour, external sheath layer on described cable core.
Also be provided with a bare copper conductor drainage thread under described screen.
Described inner restrictive coating and external sheath layer all adopt and extrude the cross-linking radiation polyolefine material and extrude.
Described armour adopts the almag wire material to make.
Beneficial effect of the present invention:
1, the present invention is adopting aluminium-plastic tape separated-shielding and aluminum-magnesium alloy wire always to shield, cable has low electric capacity and low inductance, there is good shielding properties and interference free performance, improved greatly the shielding properties of cable, there is good anti-external electromagnetic field and disturb and do not produce external interference.
2, the present invention is adopting aluminium-plastic tape separated-shielding and aluminum-magnesium alloy wire always to shield, and this bi-material proportion is low, greatly reduces the weight of cable, does not affect again the shield effectiveness of cable.
3, the present invention's insulation and interior oversheath all adopt the cross-linking radiation polyolefin, have improved the temperature resistant grade of cable, and the fire resistance of cable is good, and resistance to ag(e)ing is good, have also improved the mechanical performance of cable simultaneously.
The 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.
The present invention is in concrete enforcement, tinned copper conductor 1 adopts restraints the structure that tangles, be extruded with irradiation crosslinked polyolefin insulating layer 2 on conductor, then two pairs of insulated wire cores twist together with a unit, wrapped polyester belt 3 of while, at the wrapped aluminium-plastic tape screen 4 in polyester belt outside, place a bare copper conductor drainage thread 4 times at screen, then a plurality of screen units are stranded together with fire-retardant gasket for packing 5, then carry out the wrapped formation lapping layer 6 of fire-retardant band, extrude cross-linking radiation polyolefin inner restrictive coating 7 in lapping layer 6 outsides, in inner restrictive coating 7 outsides, use aluminum-magnesium alloy wire as braiding armour 8, the armour outside extrudes cross-linking radiation polyolefin external sheath layer 9.
The present invention has low electric capacity and low inductance, has good shielding properties and interference free performance.Improved greatly the shielding properties of cable, there is good anti-external electromagnetic field and disturb and do not produce external interference.Cable is lightweight, lays conveniently, 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.
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 produced does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
