Abstract
The utility model discloses a kind of flexible fireproof cable, it relates to technical field of electric wires and cables, strands conductor and wrapped fire-resistant wrapping tape layer outside conductor and the refractory insulating layer extruded outside described fire-resistant wrapping tape layer form insulated wire cores, many described insulated wire cores are twisted into cable core, cable core gap-fill has packed layer, the outer overlap of described cable core is surrounded with lapping layer, is extruded with flexibility oversheath outside it.Its flame retardant coating adopts double-decker, and synthetic mica tape lapping layer and the double-deck fireproof construction of Ceramic silicon rubber insulating barrier, greatly improve the fire resistance of cable, conductor adopts ultra-soft conductor, and insulation and sheath material all adopt the material that flexility is higher.Coordinate the flexible fireproof cable that Cable Construction Design goes out, there is excellent flexility, flame retardant coating, insulating material, packing material, band material and jacket material all adopt halogen-free environmental novel high polymer material, meet the instructions for use of environment-friendly cable completely.
Description
technical field:
The utility model relates to a kind of flexible fireproof cable, belongs to technical field of electric wires and cables.
background technology:
along with the raising of people's environmental consciousness and the quickening of Chinese society economic construction paces, public safety item is taken seriously all the more.A kind of flexible fireproof cable is widely used in the densely populated public place such as skyscraper, hospital, market, school, when a fire, cable line can keep normal operation within a certain period of time, do not discharge corrosive gas during cable fire simultaneously, and light transmission is good, rescue work is very helpful, casualties and damage to property can be reduced to a great extent.
The development of domestic flexible fireproof cable is started late, the technical merit of each producer is uneven, add more and more higher to requirement that is fire-retardant, fire-resistant, environmental protection in recent years, cause many producers due to technical force limited, can not design, produce the flexible fireproof cable product meeting technical requirement.This just requires that producer must break-through skill barrier, sets up the R&D team of oneself, develops the product with independent intellectual property rights.
utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of flexible fireproof cable.
Flexible fireproof cable of the present utility model, it comprises conductor 1, fire-resistant wrapping tape layer 2, refractory insulating layer 3, packed layer 4, lapping layer 5 and oversheath 6, strands conductor 1 forms insulated wire cores with wrapped fire-resistant wrapping tape layer 2 outside conductor 1 and the refractory insulating layer 3 extruded outside described fire-resistant wrapping tape layer 2, many described insulated wire cores are twisted into cable core, cable core gap-fill has packed layer 4, the outer overlap of described cable core is surrounded with lapping layer 5, is extruded with flexibility oversheath 6 outside it.
As preferably, described conductor 1 adopts that super soft copper wire is stranded to be formed, and filament diameter is less than the regulation of the 6th kind of ultra-soft copper conductor of national Specification, conductor layer any surface finish, impulse-free robustness, greasy dirt, and conductor resistance meets standard regulation.
As preferably, described flame retardant coating 2 adopts synthetic mica carrying material, and double-layer overlapping is wrapped outside above-mentioned conductor 1, wrapped smooth, puts up evenly.
As preferably, described refractory insulating layer 3 is Ceramic silicon rubber insulating material.Extrude outside above-mentioned flame retardant coating 2, smooth in appearance, rounding, thickness is even.
As preferably, described packed layer 4 adopts halogen-free flameproof glass fiber, fills rounding.
As preferably, described lapping layer 5 adopts high temperature resistance non halogen low-smoke and flame retardant glass fiber tape lapping layer overlapping wrapped outside cable core.
As preferably, described oversheath 6 adopts flexibility halogen-free low-smoke thermoplastic elastic material, and extrude outside above-mentioned cable core 5, smooth in appearance, rounding, thickness is even.
The beneficial effects of the utility model: 1, its flame retardant coating adopts double-decker, synthetic mica tape lapping layer and the double-deck fireproof construction of Ceramic silicon rubber insulating barrier, greatly improve the fire resistance of cable, silicon rubber insulation also has excellent electrical property, mechanical performance, pliability and environmental-protecting performance simultaneously.
2, conductor adopts ultra-soft conductor, and insulation and sheath material all adopt the material that flexility is higher.The flexible fireproof cable coordinating Cable Construction Design to go out, have excellent flexility, bending radius can reach the cable size of 4 times.
3, flame retardant coating, insulating material, packing material, band material and jacket material all adopt halogen-free environmental novel high polymer material, not only there is excellent flame-retarding characteristic, environmental-protecting performance, have more the characteristic such as Halogen, low cigarette, meet the instructions for use of environment-friendly cable completely.
