In recent years, along with skyscraper, public venue increase gradually, cable is aging and cause the accident of short circuit and fire hazard increased.Therefore, people more and more pay attention to the fireproof cable meeting fire-fighting requirements, and fireproof cable is also used in a large number, become the main trend of the cable development for building of China from now on.The existing several fireproof cable of domestic market: one is magnesium oxide mineral insulation cable, and fire protecting performance is the most excellent, but cable bend is poor, manufacturing process is complicated, and price is high, insulation moisture-sensitive, and installation is more complicated; Two is ordinary mica tape fire-resisting cables, and technique is comparatively simple, and cost is lower, but fire resistance lower grade, can not Reusability; Three is plain edition metallic sheath flexible fire-proof cables, and fire protecting performance is better, but refractory insulating layer moisture-sensitive, electrical insulation properties are unstable, and useful life is short.
Utility model content
The purpose of this utility model is to provide a kind of flexible fire-proof cable, to solve the problems such as existing fireproof cable flexibility is poor, insulative water-proof is poor, manufacturing process is difficult, laying installation is inconvenient, improve fire line, flexibility, the water proofing property of fireproof cable, and optimize manufacturing process, reduce the difficulty of laying installation, improve the useful life of cable.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of flexible fire-proof cable, be disposed with copper conductor, flame retardant coating, insulating barrier, fire proof heat-insulation layer, ceramic fibre heat insulating belt, metal inner sheath and outer jacket from the inside to the outside, wherein, copper conductor adopts many copper wire concentric type lay configuration, flame retardant coating is the fire-resistant composite band of ceramic silica gel, insulating barrier is irradiation crosslinking type halogen-free and low-smoke flame-retardant polyolefin, fire proof heat-insulation layer is high flame retardant Ceramic silicon rubber, metal inner sheath is corrugated copper pipe or stainless steel tube, and outer jacket is high flame resistance, low smoke halogen-free polyolefin.
The conductor of above-mentioned cable adopts many copper wire concentric type lay configuration, has excellent electric conductivity; The fire-resistant composite band of the overlapping wrapped multi-layer ceramics SiClx glue of every root copper conductor outer surface, forms core flame retardant coating, can stand the test of 950 DEG C/180min flame combustion.Extrude one deck irradiation crosslinking type halogen-free and low-smoke flame-retardant polyolefin insulating barrier outside flame retardant coating, there is good electric insulating quality, low cigarette, nontoxicity, and 150 DEG C of temperature-resistance characteristic.Cable divides single core pattern, multi-core type, and several insulated wire cores of multi-core type cable are mutually stranded forms cable core, and the gap of cable core and surface extrude one deck high flame retardant Ceramic silicon rubber, forms fire proof heat-insulation layer, lap wound bag one deck ceramic fibre heat insulating belt of laying equal stress on.Adopt vertical bag and seamless welding embossing technique, by certain thickness copper strips or stainless steel band, make one deck corrugated copper pipe or stainless steel tube is coated on ceramic fibre heat insulating belt outer surface, as metal inner sheath, play the effects such as waterproof, fire prevention, oxygen barrier, mechanical protection.Extrude one deck high flame resistance, low smoke halogen-free polyolefin oversheath outside metal inner sheath, possess excellent anti-flammability, low cigarette, hypotoxicity.
The beneficial effect of this utility model is: the novel flexible fireproof cable that the utility model relates to, compared with existing fireproof cable, there is excellent fire protecting performance, flexibility, insulative water-proof, the features such as manufacturing process is simple, cost is lower, laying installation is convenient, meet the CWZ burning test requirement in BS6387, the fire protection electric requirement that building place is high-grade can be met completely.
