Abstract
The utility model discloses a isolation-type plastic insulated insulated fireproofing cable. The cable comprises a plurality of insulated cable cores, a composite isolation layer and a sheath layer. The composite isolation layer is wrapped around the insulated cable cores; a filler is arranged among the insulated cables; the insulated cable core comprises a conductor and an insulated layer; the composite isolation layer comprises a heat insulation layer and a cooling layer; and a sheath layer is arranged outside the composite isolation layer. The conductor is composed of a plurality of twisted high-purity oxygen-free copper wires; the insulation layer is made of irradiation crosslinked polyethylene material; the filler is high temperature filling ropes; the heat insulation layer is made of ceramic fiber bands with extremely low thermal conductivity; the cooling layer is processed from clean high-glue glass fiber tape; and the sheath layer is processed from a non-magnetic metal material. The utility model has the advantages of high temperature resistant grade, low oxygen content, easy installation, waterproofness, long service life, safety, reliability, energy saving and environment-friendliness, and can solve the problem of severe voltage drop under fire of a fireproof cable in the prior art.
Description
Technical field:
The utility model relates to a kind of fireproof cable, particularly relates to a kind of isolated form plastic insulation fireproof cable for fields such as security against fires, belongs to special fireproof cable technology field.
Background technology:
Fireproof cable obtains widely purposes in fields such as current commercial building, industrial plants, residential buildings, being mainly used in fire-fighting emergent uses, can after occuring, guarantee fire electric power, the control circuit phenomenon that is not short-circuited within a certain period of time, for the fire-fighting rescue provides sound assurance.The fireproof cable that generally uses at present has two kinds: a kind of band that adopts mica tape and so on is coated on and forms flame retardant coating on the conductor, jointly forms insulating barrier by flame retardant coating and macromolecular material; Another then uses mineral powders to be filled in around the conductor, plays insulation and fire-resistant effect.These two kinds of cables all can rise rapidly in strong flame lower conductor temperature; finally near the external flame temperature; because conductor resistance and temperature relation are close; when temperature during 600 ℃ of left and right sides; conductor resistance can be brought up to about 3 times under the Normal Environmental Temperature; voltage drop then is original 3～4 times, and too high voltage drop meeting is not even worked the terminal facilities irregular working, can bring to fire-extinguishing and lifesaving to seriously influence.
The utility model content:
Technical problem to be solved in the utility model is: provide that a kind of temperature resistant grade is high, oxygen content is low, easy installation, waterproof, life-span are long, safe and reliable, the isolated form plastic insulation fireproof cable of energy-conserving and environment-protective, can solve existing fireproof cable serious problem of voltage drop under fire.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of isolated form plastic insulation fireproof cable, consisted of by many eradications edge cable core, compound insulation layer and restrictive coating, described compound insulation layer surrounds the edge cable core outsides of thoroughly doing away with more, be provided with filler thoroughly do away with between the edge cable core more, described insulation cable core comprises conductor and insulating barrier, described compound insulation layer comprises thermal insulation layer and cooling layer, is provided with restrictive coating in the compound insulation layer outside.
Described insulation cable core is two or more.
Described conductor is processed by many high purity oxygen free copper silks.
Described insulating barrier is formed by IXPE materials processing, and temperature resistant grade reaches more than 105 ℃.
Described filler is high temperature packing rope.
Described thermal insulation layer is processed by the extremely low ceramic fibre strip of thermal conductivity.
Described cooling layer is processed by the high sized glass fibre band of clean type.
Described restrictive coating is processed by non-magnetic metal protective sleeve, and temperature resistant grade reaches more than 850 ℃.
Positive beneficial effect of the present utility model is as follows:
1, conductor of the present utility model is to be closed by the some identical high purity oxygen free copper skein silks of diameter to form, and conducts electricity very well, and oxygen content is low, and high temperature is not easy to occur oxidative phenomena; Insulating barrier is IXPE, and temperature resistant grade is high, and stable performance thoroughly does away with the edge core more and consists of cable conductor, and the cable conductor outside coats compound insulation layer, can discharge moisture content and reduce the cable internal temperature; Thermal insulation layer in the compound insulation layer is that the extremely low ceramic fibre strip of thermal conductivity, cooling layer are the high sized glass fibre band of clean type, and the outside of compound insulation layer is metal sheath layer.Above all material is all not halogen-containing, and cable can reach the performance requirement of halogen-free environmental.
2, restrictive coating of the present utility model is formed by the non-magnetic metal protective sleeve materials processing of heatproof more than 850 ℃, by being coated on the compound insulation layer without joint stabilizing process, not only can satisfy the fireproofing of cable requirement, more can reduce because of the adverse effect that seriously use causes to terminal equipment of voltage drop under the hot environment, and can be behind fire long-term normal the use, have that waterproof, life-span are long, safe and reliable, the remarkable advantage of energy-conserving and environment-protective.
3, the utility model employing macromolecular material is insulating barrier, nonhygroscopic, it is little that insulation property are affected by environmental change, the metal sheath layer that adopts can make cable not fire fully, play real flameproof effect, still can normally use at fire later cable, have that the life-span is long, fire protecting performance is excellent, a waterproof, safe and reliable characteristics.
4, the utility model adopts compound insulation layer as fireprotection layer, isolated insulation cable core and extraneous flame, can reduce the temperature rise speed of cable conductor under flame, in the insulation of fireproof cable in setting time punch-through not occuring, is reaching the user demand of satisfying all kinds of terminal equipments when fire protecting performance requires.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Referring to Fig. 1, a kind of isolated form plastic insulation fireproof cable, consisted of by many eradications edge cable core, compound insulation layer and restrictive coating 6, described compound insulation layer surrounds the edge cable core outsides of thoroughly doing away with more, be provided with filler 3 thoroughly do away with between the edge cable core more, described insulation cable core comprises conductor 1 and insulating barrier 2, and described compound insulation layer comprises thermal insulation layer 4 and cooling layer 5, in the compound insulation layer outside restrictive coating 6 is set.Wherein: conductor 1 is closed by many high purity oxygen free copper skein silks and forms; Insulating barrier 2 is formed by IXPE materials processing; Filler 3 is high temperature packing rope; Thermal insulation layer 4 is processed by the extremely low ceramic fibre strip of thermal conductivity; Cooling layer 5 is processed by the high sized glass fibre band of clean type; Restrictive coating 6 is processed by nonmagnetic material.
