Abstract
The utility model discloses a marine control and instrument cable. Each conductor is formed by twisting multiple strands of tinned copper wires, a cross-linked polyolefine insulation layer is extruded on each conductor to form an insulation wire core, every two pairs of insulation wire cores are twisted together as one unit and wrapped by a polyester tape, and an aluminum-plastic composite tape shielding layer is further arranged on each polyester tape to form a shielding unit; a plurality of shielding units and a flame-retardant filling rope are twisted together to form a cable core; and a flame-retardant cover tape wrapping layer, an inner sheath layer, a woven armor layer and an outer sheath layer are respectively arranged on the cable core from inside to outside. The marine control and instrument cable disclosed by the utility model has the advantages of light weight, convenience in laying, good flame retardance of the cable, excellent aging resistance, low capacitance, low inductance and good shielding performance and anti-interference performance.
Description
Technical field
The utility model relates to a kind of instrument cable, relates in particular to a kind of control peculiar to vessel and instrument cable, 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 the places such as water accumulation steam or harmful steam may be arranged.Because the space that shipboard cable lays is narrower and small, is difficult for laying, cable weight is heavier, gives to lay and has brought very inconvenience.
The utility model content
The utility model provides a kind of simple in structure, lightweight, control peculiar to vessel and instrument cable that volume is little.
Scheme of the present utility model is as follows: a kind of control peculiar to vessel and instrument cable, its conductor is stranded with the multiply tinned wird, extrude the cross-linked polyolefin insulating barrier at described conductor and consist of insulated wire cores, per two pairs of insulated wire cores twist together and wrapped polyester belt with a unit, also have the aluminium-plastic tape screen to consist of a screen unit at polyester belt; A plurality of screen units and fire-retardant gasket for packing be stranded formation cable core together; Be respectively equipped with from inside to outside fire-retardant band lapping layer, inner restrictive coating, braiding armour, external sheath layer on the described cable core.
Also be provided with a bare copper conductor drainage thread under the 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.
The beneficial effects of the utility model:
1, the utility model is adopting aluminium-plastic tape separated-shielding and aluminum-magnesium alloy wire always to shield, cable has low electric capacity and low inductance, have good shielding properties and interference free performance, improved greatly the shielding properties of cable, have good anti-external electromagnetic field and disturb and do not produce external interference.
2, the utility model 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 utility model 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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model is in implementation, tinned copper conductor 1 adopts restraints the structure that tangles, be extruded with irradiation crosslinked polyolefin insulating layer 2 at 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 and fire-retardant gasket for packing 5 are stranded together, 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, use aluminum-magnesium alloy wire as braiding armour 8 in inner restrictive coating 7 outsides, the armour outside extrudes cross-linking radiation polyolefin external sheath layer 9.
The utlity model has low electric capacity and low inductance, have good shielding properties and interference free performance.Improved greatly the shielding properties of cable, had 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 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 modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
