The cable is characterized by comprising two alloy conductors wrapped with insulating layers, wherein the two alloy conductors are mutually twisted to form a cable core; the pitch ratio of the cable core is 11 to 14 times higher; each alloy conductor is intertwisted by a plurality of silvering high-strength alloy wires; two filling cores are arranged on the upper side and the lower side of the cable core; a shielding layer is disposed outside the cable core and the filling cores; and a sheath layer is molded outside the shielding layer in an extrusion moulding manner. The cable of the utility model occupies a small laying space, is light in weight, high in mechanical strength and fine in electric insulation, is flame-retarding and durable, exhibits excellent ionizing radiation resistance and vacuum gas-free performance, exhibits fine high and low temperature resistance and oxygen stability, and helps to provide the service with highly-reliable quality under a severe environment.
Description
Technical field:
The utility model relates to navigation, vehicle-mounted, ship net ruton credit field of cables, relates in particular to a kind of radiation proof high-low temperature resistant data network cables.
Background technology:
One mentions the high temperature cable, and insulation expects using fluoroplastics naturally with sheath, because fluoroplastics are in thermoplastic processing; No matter electrical property, mechanical performance, ageing resistance and high and low temperature resistance etc. are the most stable with temperature and frequency change; Communication quality is the highest, but has a fatal shortcoming, and mechanical performance sharply descends in the environment of radiation is arranged; As in a vacuum, absorbed dose reaches 10
4During Gy, polymer takes place significantly to decompose.In atmospheric environment, when absorbed dose reached 200Gy, percentage elongation will change, to 10
4During Gy, tensile strength drops to 50% of original value, and percentage elongation is very low.
Customer demand is a kind of in the environment of ray is arranged; The high-low temperature resistant data network cables; In order to satisfy the needs of client's particular surroundings; Will seek a kind of material and not only possess property at high and low temperature, also will have in the environment of ionising radiation simultaneously, material electrical property and mechanical performance are unaffected, guarantee cable good communication quality in rugged environment.Through searching related data and to the consulting of how tame manufacture of materials producer; Material property is compared; Through screening insulation and the crosslinked tetrafluoroethylene-ethylene copolymer (XETFE) of sheath, therefore radiation proof high temperature data network cables is developed with a kind of high-low temperature resistant, radiation resistance excellence.
The utility model content:
The purpose of the utility model provides a kind of radiation proof high-low temperature resistant data network cables; Lay that the space is little, in light weight, fire-retardant, durable, mechanical strength is high, electrical insulating property good, very excellent ionized radiation resistance and vacuum ease gas property, good resistant of high or low temperature and oxidative stability etc., in rugged environment, highly reliable service quality can be provided.
The technical scheme of the utility model is following:
Radiation proof high-low temperature resistant data network cables; It is characterized in that: the alloy conductor pair twist that comprises two wrap insulate layers constitutes cable core; The pitch of stranded cable is than being 11-14 times, and alloy conductor adopts stranded the forming of the silver-plated high-strength alloy line of multiply, the filled core that it is 0.75-0.85mm that the cable core upper and lower sides is provided with two diameters; The outside of cable core and filled core is provided with screen, and screen outside extrusion moulding has restrictive coating.
Described radiation proof high-low temperature resistant data network cables is characterized in that: described insulating barrier and filled core material are crosslinked tetrafluoroethylene-ethylene copolymer.
Described radiation proof high-low temperature resistant data network cables is characterized in that: described screen is that the tinned wird braiding constitutes, and count is not less than 90%.
Described radiation proof high-low temperature resistant data network cables is characterized in that: described restrictive coating adopts the crosslinked tetrafluoroethylene-ethylene copolymer of irradiation.
The useful technique effect of the utility model is:
1, conductor is selected conductivity for use and thermal conductivity is good, corrosion resistance and non-oxidizability, chemical property are very stable, tensile strength is not less than 345N/mm
2Silver-plated high strength copper alloy line, silver thickness have satisfied the conductance height and have made the signal transmission fast greater than 1.5 μ m, and 19 strand cores adopt two-way lay configuration more stable.
2, insulation adopts that electrical insulating property is good, dielectric strength is high, density is little, volume is little, fire-retardant, resistance to weathering can be good, mechanical strength big, opposing chemical corrosion, radioresistance are good, dielectric coefficient and dielectric loss angle tangent is less with the variation of temperature and frequency, resistant of high or low temperature is good crosslinked tetrafluoroethylene-ethylene copolymer material, guarantees the communication quality under high frequency.
3, stable for guaranteeing the cable signal transmission, when pair twist, increased by 2 crosslinked tetrafluoroethylene-ethylene copolymer filled cores of diameter 0.75mm～0.85mm, the stranded cable pitch has increased the flexibility of cable than 11 times～14 times.
4, outside becoming cable core, woven the tinned wird screen that solderability is good, resistance to corrosion is strong; Count reaches more than 90%; Weaving parameter reasonable in design makes angle of weave reach optimum value when count requires satisfying, and improves anti-outer signals interference capability.
5, the crosslinked tetrafluoroethylene-ethylene copolymer material that sheath selects that tensile strength is big, fire-retardant for use, resistance to weathering can be good, radioresistance is good has not only played the mechanical protection effect to cable, the communication quality influence of adverse circumstances that do not come from the outside simultaneously.
6, research and develop the new varieties of radiation proof high-low temperature resistant data network cables of new generation for fields such as satellite navigation, vehicle electronic device, boat-carrying, naval vessel networks, enlarged user's range of choice.
