Abstract
The utility model discloses a fire-resistant power flexible cable comprising a cable core composed of at least one insulating wire core, a fire-resistant layer wrapped round the cable core, and an outer sheath wrapped round the fire-resistant layer in an extruding manner. The insulating wire core comprises a conductor produced by conductive material and a fire-resistant insulating layer wrapped round the conductor in an extruding manner. High-temperature filling ropes are filled in the gap between the insulating wire core and the fire-resistant layer. The fire-resistant layer employs ceramic fireproof and fire-resistant silicon rubber and high-temperature-resistant glass fabric composite belt material which are overlapped and which are tightened on the cable core in reverse direction. The fire-resistant power flexible cable has characteristics of good electrical insulation property, good flexible property, high-and-low-temperature-resistant performance, good fireproof and fire-resistant performance, simple processing technology, and easy transportation and installation.
Description
Technical field
The utility model relates to electric wire, especially relates to a kind of power flexible cable with fireproof＝fire-proof function.
Background technology
Development along with modern electric power industry, the sharp increase of urban population, skyscraper, hotel, large supermarket, hospital, subway, power plant, nuclear power station, warehouse, airport constantly increase, and the fireproof＝fire-proof cable is widely used in these important public places.And along with the proposition of parliament of European Union and the RoHS of EU Council environmental protection instruction, people are also more and more higher for the environmental requirement of cable.
The fireproof＝fire-proof cable of China's cable industry mainly contains two large types at present: a class is the commonplace wrapped compound fire-resisting cable that adds insulation of fire-resistant isinglass belt; One class is the insulating protective metal shell of mineral cable.The insulating protective metal shell of mineral cable needs special-purpose production equipment, and fund input is large, and production cost is high, and oversheath is metal material, product than great, bending radius is little, transportation, mounting and installation difficulty are large; Mica tape class fire-resisting cable then can not be by spray, vibratory test, existing a lot of mica tape again thicker, binder content is high, hardness is large, mica sheet comes off easily in wrapped or crooked process, and mica tape is of a great variety, quality is uneven, and less stable is difficult to guarantee its fire resistance quality.
Summary of the invention
The purpose of this utility model is to provide a kind of fire-resistant power flexible cable, to overcome the existing technological deficiency of fireproof＝fire-proof cable, improves the fireproofing of cable fire resistance.
Fire-resistant power flexible cable of the present utility model comprises the cable conductor that forms by being no less than an eradication edge core, be centered around the flame retardant coating on the described cable conductor, and extrude outer jacket on described flame retardant coating, wherein said insulated wire cores comprises the conductor of being made by electric conducting material and is extruded in the outer field refractory insulating layer of described conductor, wherein be filled with high temperature packing rope in the slit between described insulated wire cores and flame retardant coating, described flame retardant coating adopts ceramic fireproof＝fire-proof silicon rubber and high temperature resistance glass fiber cloth composite band material, and double-layer overlapping is oppositely tightened on cable conductor.
Wherein, described conductor is by the zinc-plated soft copper conductor of multiply or stranded the forming of not zinc-plated soft copper conductor.
Described refractory insulating layer adopts the refractory ceramics fire-resistant silicon rubber to make, and outer jacket can adopt plastics, elastomer or elastomeric material to make.
The flame retardant coating of the fire-resistant power flexible cable of the utility model adopts the composite band material of ceramic fireproof＝fire-proof silicon rubber and high temperature resistance glass fiber cloth, wherein ceramic fireproof＝fire-proof silicon rubber is to add white carbon, silicone oil, antistructurizing agent and other auxiliary agent to make in high temperature silicon rubber (HTV), the performance that possesses at normal temperatures ordinary silicon rubber, form hard ceramic shell through after the calcination of thermal-flame, form the good isolation layer of one deck, make insulation still have certain mechanical strength and good electrical insulation capability; In addition, composite band flame retardant coating double-layer overlapping is oppositely tightened, composite band begins hardening under 350 ℃ and above flame condition, along with temperature raises, and rapid, complete housing hard by the Low fire ceramic shape, the cable core of protection object to be burned body is not damaged; Insulating barrier is brought into play dual synergy with the composite band flame retardant coating, makes that cable itself does not prolong combustion, do not open circuit, not short circuit, does not cut off the power supply, and plays good fireproof＝fire-proof effect.
Fire-resistant power flexible cable of the present utility model is except having higher electrical insulation capability, good softness and high temperature resistant, outside the resistance to low temperature, the cable fire function admirable, cable line still can keep the normal operation of certain hour when fire occurs, for the quality time is won in rescue work to greatest extent, can reduce casualties and damage to property to a great extent, cable insulation is non-corrosiveness when burning, toxicant and γ-ray emission, can not cause secondary harm to disaster-stricken people, be specially adapted to public fire protection, fire safety requires very high place to use.
Fire-resistant power flexible cable bending radius of the present utility model is little, and proportion is little, and easily transportation is laid, and processing technology is simple, and cost performance is high.
Description of drawings
Fig. 1 is the structural representation of the fire-resistant power flexible cable of the utility model.
Among the figure: 1-conductor; 2-refractory insulating layer; 3-high temperature resistant gasket for packing; 4-flame retardant coating; 5-outer jacket.
Embodiment
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
The structure of fire-resistant power flexible cable includes conductor 1, refractory insulating layer 2, high temperature resistant gasket for packing 3, flame retardant coating 4 and outer jacket 5 as shown in Figure 1 from inside to outside successively.The stranded conductor that forms of zinc-plated or not zinc-plated soft copper 1 and to be extruded in conductor 1 outer field material be that the refractory insulating layer 2 of refractory ceramics fire-resistant silicon rubber consists of insulated wire cores by multiply thoroughly does away with the stranded formation cable conductor of edge core more.Behind the high temperature resistant gasket for packing 3, around upper flame retardant coating 4, flame retardant coating 4 is oppositely tightened by ceramic fireproof＝fire-proof silicon rubber and high temperature resistance glass fiber cloth composite band double-layer overlapping on filling in the slit of insulated wire cores.At last, outer jacket 5 is extruded on the flame retardant coating 4, outer jacket 5 can adopt plastics, elastomer or elastomeric material.
The fire-resistant power flexible cable of present embodiment properties all meet design requirement and instructions for use, its technical performance index is: operating voltage: 0.6/1kV and following; Test voltage, time: 3.5kV/5min does not puncture; Cable Bending Radius :≤6D(D: the outside diameter of cable).
