Abstract
The invention discloses a high-temperature refractory shielded cable, which is characterized by consisting of a conductor, a refractory insulating layer, a partial shielding layer, an insulating layer, a cabled tape, a general shielding layer and an outer sheath; the components have the following connection mode that: the high-temperature refractory shielded cable contains three insulating cores; for each insulating core, the conductor is packed by the insulating refractory layer, and the partial shielding layer and the insulating layer are packed outside the insulating refractory layer in turn; and the three insulating cores are packed by the cabled tape, and the general insulating layer and the outer shield are packed outside the cabled tape.
Description
Technical field the present invention relates to the cables manufacturing field, relates to a kind of high-temperature refractory shielded cable concretely.
The instrument and equipment of background technology in industries such as space flight, mechanotronics, cogeneration power plant, metallurgy, oil, chemical industry all is in high-temperature work environment.The shielding control cable of the various electric device signals that therefore, use under these environment must possess stronger high temperature resistant and fire performance.Yet, the common high temperature shielding temperature-resistant material that control cable adopted mostly is silica gel or fluoroplastics, its temperature resistant grade is all about 250 ℃ and not fire-resistant, can cause the signal in the cable accurately not transmit when using in the environment of 500 ℃ high temperature or flame combustion, instrument and equipment can't operate as normal.
Summary of the invention the purpose of this invention is to provide a kind of high-temperature refractory shielded cable, improves the fire-resistant and temperature resistant grade of shielded type cable, and a kind of shielding control cable that can use in 500 ℃ of hot environments is provided.
The present invention is made up of following each parts: conductor, refractory insulating layer, sub-shield, insulating barrier, stranding band, total screen and oversheath is characterized in that: comprise 3 and thoroughly do away with the edge core in this high-temperature refractory shielded cable; For each insulated wire cores, utilize refractory insulating layer parcel conductor, refractory insulating layer wraps up sub-shield and insulating barrier outward successively; Utilize the stranding band to thoroughly do away with the edge core and be bundled together total screen of stranding band outer wrapping and oversheath 3.
The present invention uses mica tape, asbestos, the glass fibre insulating material as refractory insulating layer, and mica tape is a flame retardant coating, effectively raises the high temperature resistant grade of cable, and makes cable have fire resistance; Adopt the conductor of soft junction structure, the flexibility of cable and resistance to bend(ing) are improved; Sub-shield and total screen all adopt the shielding mode of woven structure, strengthened the ability of the anti-electric field of high-temperature cable, magnetic interference.Cable can be high temperature resistant, ageing-resistant and be had fire-retardant and do not prolong the good characteristic of combustion, can keep energising more than 3 hours under 800 ℃～1000 ℃ flame combustion situation.The present invention mainly is applicable to the instrument and equipment that uses under the industry high temperature such as space flight, mechanotronics, cogeneration power plant, metallurgy, oil, chemical industry.
