The utility model relates to a low-smoke halogen-free flame-retardant cable for electronic computers. The cable comprises an inner core and an outer layer coated outside the inner core, the inner core consists of two or more conductive cores, a polyester belt and a first composite belt, wherein the conductive cores are coated with an insulating layer, the polyester belt is lapped outside the conductive cores, the first composite belt is coated outside the polyester belt, an earth wire is arranged in the first composite belt, an inner laying layer, a second composite belt and a sheath layer are sequentially arranged inside the outer layer of the cable, another earth wire is arranged in the second composite belt, and a flame-retardant cable is arranged in a clearance between the outer layer and the inner core of the cable. The cable utilizes a structure of combining aluminum foil main shielding with separated shielding, can effectively reduce crosstalk among cables, and is fine in shielding effect and high in electromagnetic radiation resistant capacity. The cable is clean and smooth in appearance and low in smoke generation, is soft, flame-retardant, halogen-free and environment-friendly, meets ROHS standards of the European Union, and meets design requirements of technical innovation, environmental protection, safety and zero pollution.
Description
Technical field
The utility model relates to a kind of electronic computer cable, particularly a kind of low-smoke halogen-free flame retardant electronic computer cable.
Background technology
At present, the various power cables outside of extensive use all is enclosed with one deck cable insulation in many buildings at home.All contain halogen in the cable insulation material mostly, this power cable is the material that transmits flare, enlarges the murther of fire scope, after such insulating material is lighted, can produce a large amount of dense smoke and the very strong hydrogen halide of corrosivity, jeopardize people's life, in case harm equipment and contaminated environment are breaking out of fire in the building, both entail dangers to life also can serious environment pollution.
The utility model content
The task of the utility model patent is that a kind of low-smoke halogen-free flame retardant electronic computer cable will be provided, and can effectively solve problems such as can producing toxic gas after the halogen-containing amount height of the control cable that can effectively solve prior art that exists in the prior art, easy firing, the burning.The utility model relates to a kind of low-smoke halogen-free flame retardant electronic computer cable, comprise the cable inner core and wrap in the outer cable outer layer of cable inner core, described cable inner core is by the conductor wire core that is surrounded by insulating barrier more than two or two, wrapped polyester belt outside conductor wire core, wrapping in the first outer composite band of polyester belt forms, be provided with ground wire in described first composite band, described cable outer layer inside is followed successively by inner covering from inside to outside, second composite band and restrictive coating, be provided with ground wire in described second composite band, be provided with fire-retardant filler in the space between described cable outer layer and the cable inner core.The number of the cable inner core in the described cable outer layer is one or more.Described inner covering is a polypropylene twining package tape inner covering.Described insulating barrier and restrictive coating are the flame retardant type electric cable material with low smoke and halogen free.Described fire-retardant filler is the fire-retardant netted gasket for packing of tearing.Described ground wire is the soft twisted wire of zinc-plated multiply.Described first composite band, second composite band are aluminium-plastic tape.The utility model the time can not discharge pernicious gas and smog in burning, and is safe, environment friendly and pollution-free, widely applicable, prolongs product useful life.This product has adopted aluminium foil always to shield the structure of bonus point shielding, can effectively reduce each line to crosstalk, shield effectiveness is good, the anti-electromagnetic radiation ability is strong.Product appearance of the present utility model is bright and clean smooth, softness, and the amount of being fuming is low, fire-retardant, halogen-free environmental, meets the ROHS of European Union standard.Thereby reach the designing requirement of scientific and technical innovation, environmental protection, safety non-pollution.The utility model is widely used in the signal transmission of ac rated voltage 500V and following electronic computer system, automated system, distributing system and detecting instrument, instrument connects with many shielded type cable.
Description of drawings
Accompanying drawing is the section of structure when the utlity model has four cable inner cores.
Embodiment
Below by accompanying drawing the utility model patent is introduced.
Comprise the cable inner core among the figure and wrap in the outer cable outer layer of cable inner core, described cable inner core is made up of the conductor wire core 2 that is surrounded by insulating barrier 1 more than two or two, wrapped polyester belt 3, first composite band 4 that wraps in outside the polyester belt 3 outside conductor wire core 2, be provided with ground wire 5 in described first composite band 4, described cable outer layer inside is followed successively by inner covering 6, second composite band 7 and restrictive coating 8 from inside to outside, be provided with ground wire 9 in described second composite band, be provided with fire-retardant filler 10 in the space between described cable outer layer and the cable inner core.
The number of the cable inner core in the described cable outer layer is one or more.The cable inner core can have that two or more insulated wire cores are stranded to form, and insulated wire cores can occur in pairs, and geometry is fixed, and stability is high, but very little to the curvature influence of cable.Conductor wire core of the present utility model adopts high purity oxygen free copper, and several layers can be arranged, every layer of conductor that has some strands with uiform section, and per share have some conductor monofilament, twists to opposite between layer and the layer.
Described insulating barrier also claims polyethylene layer, and restrictive coating also claims the pe sheath layer, and insulating barrier and restrictive coating are made by the flame retardant type electric cable material with low smoke and halogen free, and this CABLE MATERIALS is the high halogen-free environmental material of a kind of oxygen index.The extrusion modling of Halogen crosslinked polyethylene insulation material, by crosslinked special processing, change polyethylene line style molecular structure into solid netted molecular structure, improved the electric property of product greatly, physical property, mechanical performance, ageing resistace and adaptive capacity to environment and other properties, not only high temperature resistant and have the advantages that not prolong the combustion and can not produce the very strong hydrogen halide of corrosivity.Cable does not just discharge pernicious gas and smog in when burning like this, and unlikely causing " secondary disaster " is safe, environment friendly and pollution-free, can be suitable for various specific occasions and lay, and prolongs product useful life.
Described inner covering is a polypropylene twining package tape inner covering, i.e. high flame retardant polypropylene (PP) inner covering band, and isolated insulation layer and outer jacket are in case bonding and influence the machinery, physics, electrical property etc. of cable mutually between them.Described fire-retardant filler is the fire-retardant netted gasket for packing of tearing, and is nonflammable, can effectively protect the cable inner core.
Described first composite band, second composite band are aluminium-plastic tape.Described ground wire 4,8 is the soft twisted wire of zinc-plated multiply, as the electric drainage by grounding line, improves Product Safety.The total shielding of aluminium-plastic tape adds ground configurations, and the aluminium foil in the aluminium-plastic tape is as total shielding, and ground configurations is as a minute shielding, and total shielding combines with dividing to shield, can effectively reduce each line to crosstalk, shield effectiveness number, the anti-electromagnetic radiation ability is strong.
