Abstract
The invention discloses a sheathed flexible cable which comprises a cable core, a refractory layer wrapping the cable core and an outer protection layer extruded on the refractory layer, wherein the cable core comprises no less than one insulated wire core. Each insulated wire core comprises a conductor made of a conductive material and a refractory insulation layer extruded on the outer layer of the conductor, a gap between each insulated wire core and the refractory layer is filled with high-temperature filler ropes, the refractory layer is made of ceramic fireproof refractory silicone rubber and high-temperature-resistant fiberglass fabric composite belt material, and the refractory layer is folded into two layers reversely fastened to the cable core. The sheathed flexible cable has excellent electric insulation property, good flexible performance, high and low temperature resistance and good fireproof and refractory performance, and is simple in processing process and convenient to transport and install.
Description
Technical field
The present invention relates to electric wire, especially relate to a kind of power flexible cable with fireproof function.
Background technology
Along with the development of 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 fireproof cable is widely used in these important public places.And along with the proposition of parliament of European Union and EU Council RoHS environmental protection instruction, people are also more and more higher for the environmental requirement of cable.
The fireproof cable of current China cable industry mainly contains two large types: a class is the commonplace wrapped compound fire-resisting cable adding insulation of fire-resistant isinglass belt; One class is insulating protective metal shell of mineral cable.Insulating protective metal shell of mineral cable needs special production equipment, and fund input is large, and production cost is high, and oversheath is metal material, product than great, bending radius is little, transport, mounting and installation difficulty are large; Mica tape class fire-resisting cable is not then by spray, vibratory test, existing a lot of mica tape again thicker, binder content is high, hardness is large, in wrapped or bending process, mica sheet easily comes off, and mica tape is of a great variety, quality is uneven, less stable, is difficult to ensure its fire resistance quality.
Summary of the invention
The object of the present invention is to provide a kind of sheath soft cable, to overcome the existing technological deficiency of fireproof cable, improve fireproofing of cable fire resistance.
Sheath soft cable of the present invention comprises by the cable conductor being no less than an insulated wire cores and forming, be centered around the flame retardant coating on described cable conductor, and the outer jacket extruded on described flame retardant coating, wherein said insulated wire cores comprises the conductor be made up of electric conducting material and is extruded in the outer field refractory insulating layer of described conductor, high temperature packing rope is filled with in gap wherein between described insulated wire cores and flame retardant coating, described flame retardant coating adopts ceramic fireproof silicon rubber and high temperature resistance glass fiber cloth composite band material, and double-layer overlapping is oppositely tightened on cable conductor.
As preferably, described conductor is formed by multiply zinc-plated soft copper conductor or not zinc-plated soft copper conductor strand.
As preferably, in described outer jacket, be also added with sillimanite.
As preferably, described conductor is copper core conductor.
As preferably, in described copper core conductor, the content of arsenic is lower than 0.35%.
As preferably, described copper core conductor external galvanized layer layer.
As preferably, described refractory insulating layer adopts 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 sheath soft cable of the present invention adopts the composite band material of ceramic fireproof silicon rubber and high temperature resistance glass fiber cloth, wherein ceramic fireproof silicon rubber in high temperature silicone rubber (HTV), adds white carbon, silicone oil, antistructurizing agent and other auxiliary agent make, possesses the performance of usual silicone rubber at normal temperatures, hard ceramic shell is formed after the calcination of thermal-flame, form the isolation layer that one deck is good, make insulation still have certain mechanical strength and good electrical insulation capability; In addition, oppositely tightened by composite band flame retardant coating double-layer overlapping, composite band starts hardening under 350 DEG C and above flame condition, along with temperature raises, and, complete housing hard by Low fire ceramic shape rapidly, the cable core of protection object to be burned body is not damaged; Insulating barrier plays dual synergy together with composite band flame retardant coating, makes cable itself not prolong combustion, not open circuit, not short circuit, not power-off, plays good fireproof effect.
Sheath soft cable of the present invention is except having higher electrical insulation capability, good softness and high temperature resistant, resistance to low temperature, cable fire function admirable, when fire occurs, cable line still can keep the normal operation of certain hour, for rescue work wins the quality time to greatest extent, casualties and damage to property can be reduced to a great extent, cable insulation non-corrosiveness, toxicant and gas when burning produce, secondary will be caused to endanger to disaster-stricken people, be specially adapted to the very high place of public fire protection, fire safety demands and use.
Sheath soft cable bending radius of the present invention is little, and proportion is little, and easily transport is laid, and processing technology is simple, and cost performance is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of sheath soft cable of the present invention.
In figure: 1-conductor; 2-refractory insulating layer; 3-high temperature resistant gasket for packing; 4-flame retardant coating; 5-outer jacket.
Embodiment
Below by way of embodiment, and the invention will be further described by reference to the accompanying drawings.
The structure of sheath soft cable as shown in Figure 1, includes conductor 1, refractory insulating layer 2, high temperature resistant gasket for packing 3, flame retardant coating 4 and outer jacket 5 from inside to outside successively.
It should be noted that in described outer jacket and be also added with sillimanite.
It should be noted that described conductor is copper core conductor.
It should be noted that the content of arsenic in described copper core conductor is lower than 0.35%.
It should be noted that described copper core conductor external galvanized layer layer.
Zinc-plated or not zinc-plated soft copper is stranded by multiply conductor 1 and to be extruded in the outer field material of conductor 1 be that the refractory insulating layer 2 of refractory ceramics fire-resistant silicon rubber forms insulated wire cores, the many stranded formation cable conductors of insulated wire cores.On filling in the gap of insulated wire cores after high temperature resistant gasket for packing 3, around upper flame retardant coating 4, flame retardant coating 4 is oppositely tightened by ceramic fireproof silicon rubber and high temperature resistance glass fiber cloth composite band double-layer overlapping.Finally, be extruded in by outer jacket 5 on flame retardant coating 4, outer jacket 5 can adopt plastics, elastomer or elastomeric material.
The present embodiment sheath soft cable 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, do not puncture; Cable Bending Radius :≤6D(D: the outside diameter of cable).
