Abstract
The invention relates to a 125-DEG C-resistant irradiation-free silane crosslinking halogen-free low-smoke flame-retardant cable. The cable comprises a plurality of conductors, insulating layers, a filling rope, a winding and wrapping band, an inner sheath, an armor layer and an outer sheath, wherein insulating wire cores are formed in a manner that the outside of each conductor is wrapped by the corresponding insulating layer in a pressing wrapping manner; a cable core is formed by winding and wrapping the insulating wire cores with the winding and wrapping band in a winding wrapping manner; the inner sheath is arranged outside the cable core; the armor layer is arranged outside the inner sheath; the outer sheath is arranged outside the armor layer; the filling rope is arranged between the insulating wire cores and the winding and wrapping band. The 125-DEG C-resistant irradiation-free silane crosslinking halogen-free low-smoke flame-retardant cable has the benefits that the cable has the characteristics of 125-DEG C-resistant and irradiation-free properties, abrasion resistance, cracking resistance, halogen-free property, flame retardation, good electrical performance and the like; the cable can satisfy and suit various kinds of densely-populated common places such as subways, ships, power stations, high-rise buildings, program-controlled switch machine rooms and computer rooms, wherein the densely-populated common places are high in flame retardation requirements and small in secondary harm.
Description
Technical field
The present invention relates to a kind of flame retardant cable, particularly relate to a kind of heatproof 125 degree and exempt from irradiation silane crosslinked halogen-free low-smoke fireproof cable.
Background technology
Tradition cross-linking radiation cable, needs the high energy electron line utilizing electron accelerator to produce to carry out cross-linking radiation to cable, and irradiation apparatus investment is large.As cooperation processing, cost of transportation directly causes the increase of cable cost; The restriction of cross-linking radiation production line irradiation speed and flow process increase, and have impact on the delivery time of cable; The conductor of cross-linking radiation cable is necessary for round, limits its application, adds product cost; The temperature resistant grade of tradition cross-linking radiation cable is 90 degree, can not meet higher heatproof demand.
Summary of the invention
The present invention provides a kind of wear-resisting cracking resistance, halogen-free flameproof to overcome the above problems, secondary harm is little, production cost is low, the heatproof of long service life 125 degree exempts from irradiation silane crosslinked halogen-free low-smoke fireproof cable.
Technical scheme of the present invention is: described cable comprises some conductors and insulating barrier, gasket for packing, twining package tape, inner sheath, armour, oversheath, the outer extruded insulation layer of described every root conductor forms insulated wire cores, the common wrapped twining package tape of described some insulated wire cores forms cable core, outside described cable core, inner sheath is set, outside described inner sheath, armour is set, outside described armour, oversheath is set, between described insulated wire cores and twining package tape, gasket for packing is set.
Described conductor is the 1st kind, the 2nd kind, the 5th kind or the 6th class flexible conductor meeting GB/T 3956-2008 requirement.
Described conductor is circular or fan-shaped or watt shape, presses or non-ly to press, the structure of plating or not plating.
Described insulating barrier is silane crosslinked halogen-free low-smoke flame-proof polyolefin insulating barrier.
Described gasket for packing is glass cord.
Described twining package tape is low-smoke non-halogen flame-retardant twining package tape.
Described inner sheath and oversheath are for exempting from irradiation halogen-free flameproof PE sheath.
Described armour is steel band or steel wire armor layer.
The present invention uses the 1st kind, the 2nd kind, the 5th kind of meeting that GB/T 3956-2008 requires or the 6th class flexible conductor, conductor can be circular or shaping (fan-shaped, watt shape), presses or non-ly to press, the structure of plating or not plating.Silane crosslinked halogen-free low-smoke flame-proof polyolefin insulating barrier, glass cord are filled, and low-smoke non-halogen flame-retardant twining package tape is wrapped, exempts from irradiation halogen-free flameproof PE sheath.Because conductor can be arbitrary shape, solve cross-linking radiation cable conductor and must use circle and cause the consumptions such as insulation and sheath material to increase, the problem that cable cost increases, insulating barrier adopts silane crosslinked halogen-free low-smoke flame-proof polyolefin Insulation Material, be characterized in heatproof, wear-resisting, cracking resistance and Halogen, fire-retardant, the performance of the cross-linking radiations such as good electrical property, the temperature resistant grade of common crosslinking insulated cable is brought up to 125 degree from 90 degree simultaneously, greatly extend the scope of application of cable, this Insulation Material can in the tepidarium of 70-80 degree Quick cross-linking, generally only need 2-4 hour, this material also can carry out cross-linking reaction under field conditions (factors) in addition, can complete crosslinked and without the need to using warm water digestion again in general 6-8 days, greatly reduce the production cost of cross-linking radiation insulation.Restrictive coating employing is exempted from irradiation halogen-free flameproof PE sheath and is made, and this material possesses excellent mechanical performance and environmental performance, and more traditional low smoke halogen-free flame-retardant polyolefin material thermal endurance brings up to 125 degree from 90 degree, thus consistent with the temperature resistant grade of insulation.The more common low smoke halogen-free flame-retardant polyolefin material of the density of this material decreases 30% in addition, significantly reduces the cost of cable.
The invention has the beneficial effects as follows: cable possesses heatproof 125 degree and exempts from irradiation, wear-resisting, cracking resistance and Halogen, fire-retardant, the features such as good electrical property, can meet be applicable to that flame-retardancy requirements is high, secondary endangers little subway, naval vessel, power station, skyscraper, programme-controlled exchange machine room, computer room and the intensive public place of the various signs of human habitation.
