Abstract
The utility model discloses a copper wire-braided overall-shielding zero-halogen low-smoke flame-retardant sheath computer cable, which relates to the field of computer cables. The utility model aims to solve the problem that a traditional computer cable has difficulty in being suitable for places with dense population and places with higher requirements on the safe reliability of equipment and the like. The wire set of the copper wire-braided overall-shielding zero-halogen low-smoke flame-retardant sheath computer cable comprises a copper twisted pair, a three-wire set or a four-wire set and a wrapping tape I wrapped outside the wire set, wherein the copper twisted pair is formed by stranding two conductors, three conductors or four conductors; a wrapping tape II, a copper wire-braided overall-shielding layer and a zero-halogen low-smoke flame-retardant polyolefin outer sheath are respectively coated on the periphery of a cable core from inside to outside. The copper wire-braided overall-shielding zero-halogen low-smoke flame-retardant sheath computer cable disclosed by the utility model has the advantages of corrosion resistance, easiness for processing and high safety and also meets the environmental-protection requirement.
Description
Technical field
The utility model relates to a kind of computer cable, particularly relates to the total shielding of a kind of copper cash braiding LSOH anti-flaming sheath computer cable.
Background technology
Be used for signal transmission and the detecting instrument of electronic computer system, monitoring loop, automation control system, the computer cable that instrument connects usefulness mainly is made up of cable core and polyvinyl chloride oversheath that polyolefin line group constitutes.Because the polyolefin insulation material has combustibility; Though and the polyvinyl chloride oversheath has certain anti-flammability; In case catch fire; The polyvinyl chloride oversheath very easily burns and can produce a large amount of hydrogen chloride toxic gases, and the equipment safety operation of the cable that uses a computer has been brought very big hidden danger, and the normal operation of electrical control equipment, electric power system and the safety of personal property in serious threat; So the security reliability of existing computer cable under fire hazard environment is low, be not suitable for as densely populated and higher place to the device security reliability requirement.
The utility model content
The purpose of the utility model is in order to overcome deficiency of the prior art, the total shielding of a kind of safe copper cash braiding LSOH anti-flaming sheath computer cable to be provided.
For realizing above-mentioned purpose, the utility model provides the total shielding of a kind of copper cash braiding LSOH anti-flaming sheath computer cable, comprises lead and cable core oversheath, and said lead comprises the conductor in insulating barrier and the insulating barrier; Said cable core comprises several line groups; Said line group by two leads, three leads or four leads stranded and paired line, three-way group or quad and the outer wrapped twining package tape one of line group form, the periphery of said cable core is coated with twining package tape two from the inside to the outside successively, copper cash weaves total screen and halogen-free and low-smoke flame-retardant polyolefin oversheath.
Said insulating barrier is a polyethylene layer, and institute's halogen-free and low-smoke flame-retardant polyolefin oversheath of addressing is for reaching LSOH anti-flaming polyethylene oversheath.
Said twining package tape one is a polyester twining package tape one, and said twining package tape two is a polyester twining package tape two.
The utility model beneficial effect is: the oversheath of the total shielding of the copper cash of the utility model braiding LSOH anti-flaming sheath computer cable cable core mainly utilizes and the characteristic of heavy metals such as the halogen-free and low-smoke flame-retardant polyolefin material is not halogen-containing and other is plumbous, cadmium, chromium, mercury; Even toxic smog such as hydrogen halides can not taken place by burning yet; Also non-corrosiveness gas release, the smog that is produced is also seldom; And this fire proofing runs into and can produce metal oxide and steam when naked light burning attacks; Metal oxide and steam have oxygen barrier, heat-absorbing action on the surface of cable core; So purpose that can effectively stop flame to burn away; Therefore even the total shielding of the copper cash of the utility model braiding LSOH anti-flaming sheath computer cable is burnt or also entail dangers to personal safety and cause secondary to endanger not when being attacked by naked light when fire takes place, and compliance with environmental protection requirements.Simultaneously the fire-retardant computer cable of the utility model is corrosion-resistant, the life-span long, be prone to processing and cost low.
Be described further below in conjunction with the total shielding of the copper cash braiding LSOH anti-flaming sheath computer cable of accompanying drawing the utility model.
