Abstract
The utility model discloses a high temperature resistant instrument cable for a ship. The instrument cable is characterized in that a conductor is formed by intertwisting multiple annealed tinning copper wires, and an insulating layer of polyetherimide (PEI) engineering plastics is extruded from the conductor to form an insulating conductor core; two conductor cores are intertwisted to form a paired unit, and a unit tinning copper lead, a tinning copper wire braiding unit shielding layer and an overlapped wrapping polytetrafluoroethylene belt layer are successively arranged on the paired unit from inside to outside to form a unit paired group; and multiple unit paired groups are intertwisted and cabled to form a cable core, and a shielding lead, a tinning copper braiding total shielding layer and an oversheath layer formed by extruding PEI engineering plastics are successively arranged on the external surface of the cable core from inside to outside. The instrument cable core of the utility model can be used as connecting lines for high-temperature signal transmission and signal control devices, is characterized by electromagnetic interference resistance, high temperature resistance, oil resistance, flame retardation and the like, and has the advantages including flexibility, low weight, small structure and long service life.
Description
Technical field
The utility model relates to a kind of new type of ship instrument cable, relates in particular to a kind of high temperature resistant type instrument cable for vessels, belongs to technical field of electric wires and cables.
Background technology
In recent years, along with the resource exploitation maturity of technology of ocean is more and more higher, and the needs of the development of shipping interest and Defence business, the manufacture level on naval vessel is more and more higher.The Ship Automation level has represented the important fiducial mark of a national marine equipment, and therefore, electric wire is as one of important accessory in naval vessel, and it will meet the growth requirement of Modern Ships.At the naval vessel special area, in the control circuit such as engine, need to have the cable of property.Need to have high temperature resistant, oil resistant, corrosion-resistant, the requirement such as light in structure is little.Existingly commonly be difficult to reach this field to its requirement with instrument cable.
Summary of the invention
The utility model is for avoiding the existing weak point of above-mentioned prior art, one connecting line that can be used for signal high-temperature region transmission and signal control device is provided, have anti-electromagnetic interference, high temperature resistant, oil resistant, the characteristic such as fire-retardant, have simultaneously the high temperature resistant type instrument cable for vessels of softness, lightweight, the advantage such as structure is little, the life-span is long.
The utility model technical solution problem adopts following technical scheme:
The characteristics of a kind of high temperature resistant instrument cable for vessels of the utility model are that conductor adopts many stranded the forming of tin annealed copper wire, extrude the insulating barrier formation insulated wire cores that Polyetherimide Engineering Thermoplastics forms at described conductor; Per two thoroughly do away with the edge core is twisted into the pair twist unit, on described pair twist unit, set gradually from inside to outside unit tin-coated copper drainage thread, tinned copper wire weaving unit screen and overlapping wrapped polytetrafluoroethylene belt Component units pair twist group, many root units pair twist group twisted synthesizing cable consists of cable core, sets gradually from inside to outside shielding drainage thread, tinned copper wire braided overall-shielding layer and extrude Polyetherimide Engineering Thermoplastics at the outer surface of described cable core to form external sheath layer.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model can be used for the connecting line of signal high-temperature region transmission and signal control device, has anti-electromagnetic interference, high temperature resistant, oil resistant, the characteristic such as fire-retardant, has simultaneously softness, lightweight, the advantage such as structure is little, the life-span is long.
2, the utility model structural design is simple, scientific and reasonable, manufacture easily, cable insulation and oversheath adopt Polyetherimide Engineering Thermoplastics, high temperature resistant and dimensionally stable, have the premium properties such as fire-retardant, good electric property, high strength, high rigidity, be mainly manifested in:
The electric property that it is good and mechanical performance satisfy the requirement of low-voltage cable;
High temperature resistant, heat distortion temperature is 198～208 ℃, can be 160～180 ℃ of lower long-term uses, and allowing intermittently, maximum operation (service) temperature reaches 200 ℃;
Good mechanical strength, electrical insulation capability, radiation resistance, high-low temperature resistant and fatigue performance and processing and forming;
Good fire resistance, oxygen index are 47%, and the burning grade is the UL94-V-0 level, and far above common fire proofing, the burning smoke intensity is low;
Good chemical-resistance, the chemical substances such as ability mineral oil, soda acid, ozone.
3, the utility model construction of cable size is less, and bending radius is little, lays conveniently, makes to meet the naval vessel to the stricter place use of physical dimension.

Fig. 1 is the utility model structural representation;
Number in the figure: 1 conductor, 2 insulating barriers, 3 unit tin-coated copper drainage threads, 4 unit screens, 5 polytetrafluoroethylene belts, 6 cable cores, 7 shielding drainage threads, 8 total screens, 9 external sheath layers.
Embodiment
Referring to Fig. 1, the version of present embodiment high temperature resistant type instrument cable for vessels is: conductor 1 adopts many stranded the forming of tin annealed copper wire, extrudes the insulating barrier 2 formation insulated wire cores that Polyetherimide Engineering Thermoplastics forms at conductor 1; Per two thoroughly do away with the edge core is twisted into the pair twist unit, on the pair twist unit, set gradually from inside to outside unit tin-coated copper drainage thread 3, tinned copper wire weaving unit screen 4 and overlapping wrapped polytetrafluoroethylene belt 5 Component units pair twist groups, many root units pair twist group twisted synthesizing cable consists of cable core 6, sets gradually from inside to outside shielding drainage thread 7, tinned copper wire braided overall-shielding layer 8 and extrude Polyetherimide Engineering Thermoplastics at the outer surface of cable core (6) to form external sheath layer 9.
In the implementation, conductor 1 needs to adopt tin annealed copper wire, requires its performance to meet the requirement of GB/T3956-1997 the 1st or the 2nd kind of zinc-plated flexible conductor, and specification is 0.5 mm
