Description
Technical field
The utility model relates to cable technology field, relates in particular to a kind of fire resistant flexible control cables.
Background technology
It has often been said that floods and fires have no mercy, since the mankind find fire, fire has not only accelerated the development of human civilization, also to human civilization, has brought destruction, and the civilization in how many ancient times is destroyed in big fire.Sharp increase along with urban population, skyscraper, hotel, large supermarket, hospital, station, airport constantly increase, subway, tunnel and large-scale place of public amusement, public transit facility are also sharply increasing, and the importance of security against fire shows especially out; Particularly how under fire condition, ensure within a certain period of time the unimpeded of electric power and communication line, try to gain time precious to one to greatest extent, minimizing personnel injury and property loss; Therefore, the engineers of various countries is all stepping up to develop to study carefully to grind the fireproof cable that can guarantee to greatest extent personal safety as well as the property safety.At present, domestic You Jin various schools of thinkers enterprise is at the fire-retardant fireproof cable of producing for fire-fighting system, but really have produce fireproof cable qualification producer seldom.The product of most producers is not the qualified product of fire prevention Check and Inspection; along with the quickening of scientific and technological progress and modernization construction paces and the heavy losses that fire causes in recent years; fireproof cable produce market demand is increased day by day; but because the cable using on present market is all that performance is single substantially; can not there is well fire-retardant and fire protecting performance simultaneously; run into burst fire condition under cable can not play protection device security normally move; can not start fire-extinguishing apparatus by normal power supply, the safe escape that affects personnel causes damage.Thereby be necessary to develop the fire resistant flexible control cables that a kind of structural material has fire-retardant fireproof environmental-protecting performance, to break above-mentioned present situation.
Utility model content
The utility model object is exactly in order to make up the defect of prior art, and a kind of fire resistant flexible control cables is provided.
The utility model is achieved through the following technical solutions:
A kind of fire resistant flexible control cables, include conductor and oval silica gel skeleton, in the outside of conductor, be coated with successively mica tape flame retardant coating and organosilane crosslinked polyethylene insulation layer, inner side and left and right sides at described oval silica gel skeleton are placed with respectively conductor formation cable core, in the outside of cable core, be coated with successively glass fibre lapping layer, ceramic silicon rubber separator, aluminium strip lock armo layer, tinned copper wire woven shield and the smokeless polyolefin oversheath of low halogen, in the inner side of described glass fibre lapping layer, be provided with glass cord packed layer.
Insulation is for composite structured, and conductive surface is first wound around double-deck fire-resistant isinglass belt hot-face insulation, then extrudes the good organosilane crosslinked polyethylene of electric property and makes insulating barrier;
Space between electric wire adopts glass cord packed layer, increases the tensile strength of cable, guarantees that cable has good roundness; Serviceability temperature wide ranges can be used for a long time within the scope of-70～200 ℃; After 650～3000 ℃ of temperature or flame condition burning, form rapidly hard housing, play the fire-resistant effect of fire insulation; Excellent insulation performance, good heat conduction effect, can reduce heat accumulation.Electric wire outside adds high-intensity heat-proof corrosion resistant glass fiber package band and carries out wrapped;
Screen adopts tinned copper wire braid shielded, prevents cable other line group equipment generation interference to external world, has also completely cut off extraneous interference simultaneously;
The separator of this cable is ceramic silicon rubber, a kind of " revolutionary character ", fireproof electric wire cable " new material ", there is special fire resistance, thermal-shock resistance, manufacturability, the feature of environmental protection, crust property and thermal insulation are far above at fire-resistant wire and cable, it can form self-supporting ceramic body in flame, there is certain intensity, electrical property is good, Halogen, low cigarette, low toxicity, from putting out, environmental protection, easily processing, can simplify the production technology of general fire-resisting cable and reduce costs, even if can be good at protecting cable exterior portion in fire, burnt the operation that can also guarantee internal security.
Outer jacket adopts high flame retardant rank halogen-free polyolefin plastics, burning can be limited in subrange, does not produce and spreads, and the low cigarette of environmental protection, does not produce pernicious gas, keeps other various device, avoids resulting in greater loss.
The utility model has the advantages that: the utlity model has special fire resistance, thermal-shock resistance, manufacturability, the feature of environmental protection, crust and thermal insulation, it can form self-supporting ceramic body in flame, there is certain intensity, electrical property is good, Halogen, low cigarette, low toxicity, certainly put out, environmental protection, easily processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of fire resistant flexible control cables, include conductor 1 and oval silica gel skeleton 2, in the outside of conductor 1, be coated with successively mica tape flame retardant coating 3 and organosilane crosslinked polyethylene insulation layer 4, inner side and left and right sides at described oval silica gel skeleton 2 are placed with respectively conductor 1 formation cable core, outside at cable core is coated with glass fibre lapping layer 5 successively, ceramic silicon rubber separator 6, aluminium strip lock armo layer 7, the smokeless polyolefin oversheath 9 of tinned copper wire woven shield 8 and low halogen, inner side at described glass fibre lapping layer 5 is provided with glass cord packed layer 10.
