Description
Technical field
The utility model relates to construction of cable technical field, is specially the super soft fire-resisting cable of a kind of modification high flame retardant.
Background technology
In the last few years, domestic repeatedly occur that large-scale place of public amusement, chemical industry, colliery, mall fire cause painful people's life and property heavy losses after, people have had more deep understanding to fire-fighting, fire safety.Along with the sharp increase of urban population, skyscraper, hotel, large supermarket, hospital, station, airport constantly increase, the construction of subway, tunnel traffic, and large-scale Public Physical Education, public place of entertainment, public transit facility increase, the importance of fire-fighting, fire safety shows especially out.
What adopt both at home and abroad at present is the fire-resisting cable that the exhausted gorgeous hot-face insulation cable of magnesium oxide mineral and mica tape are wound around insulation mostly.Magnesium oxide mineral insulation hot-face insulation cable needs special manufacturing and processing equipment, produces the production equipment complex process of magnesium oxide mineral hot-face insulation cable in addition, and very expensive, and fund input is too large; In addition, the outer jacket of magnesium oxide mineral insulation hot-face insulation cable is full copper, higher in cost, by restriction to a certain extent in practical application; Add the particular/special requirement of copper sheath magnesium oxide mineral insulation hot-face insulation cable in the process such as laying installation and use of production and processing, transport, circuit, production and processing as magnesium oxide mineral insulation hot-face insulation cable can not be convenient image height molecular material, laying installation difficulty is large, cost of raw material cost is high, be difficult to universal on a large scale use, be difficult to especially promote on civil buildings.Mica tape is wound around the fire-resisting cable of insulation, need multi-lay winding in process of production, due to the restriction of process conditions, overlapping the slot place is often easily caused to occur defect, mica tape embrittlement after burning, easily come off, also cause fire-resistant weak effect, thus be difficult to ensure communication, electric power in case of fire safe and smooth.
Summary of the invention
For the problems referred to above, the utility model provides the super soft fire-resisting cable of a kind of modification high flame retardant, it adopts ceramic complex mineral to insulate and the chain armouring of stainless steel band, heatproof after insulating ceramics reaches more than 2600 DEG C, the heatproof of stainless steel band reaches more than 1500 DEG C, therefore the utility model fire resistance rating is better than mineral insulation fire-resisting cable equally; Bending property is better than all kinds of fire-resisting cable, and bending radius is about 10 times of cable size.
The super soft fire-resisting cable of a kind of modification high flame retardant, its technical scheme is such: it is made up of multiple insulated wire cores and protection skin, protection skin surrounds outside multiple insulated wire cores, inner sheath is provided with between insulated wire cores and protection skin, it is characterized in that: multiple described insulated wire cores stranded formation stranding cable core, the periphery of described stranding cable core is vertical is surrounded by the fire-resistant composite band of ceramic, the center of described stranding cable core is semi-cure ceramic composite mineral matter packing, the outer rim of described semi-cure ceramic composite mineral matter packing is close to the inner side cambered surface of the described insulated wire cores of correspondence position respectively, described protection outer from outer in the cross-sectional structure that is arranged in order be the circular chain armouring sheath of steel band, alkali-free glass fibre band, described inner sheath is specially ceramic composite mineral matter inner sheath, described insulated wire cores from outer in the cross-sectional structure that is arranged in order be ceramic composite mineral matter insulating barrier, copper conductor.
