Background technology
The industry such as public fire protection, chemical industry, outdoor study is when inflammable and explosive occasion operation, need to use mobile device to carry out power conveying, illumination, information transmission, because mobile device will often move around, cable is needed to have certain pull resistance and crushing resistance, consider the fail safe of its cable and personnel and the particularity in place, cable itself needs certain fire line, common fire-resistant class cable is based on mica tape, the performance of mica flame retardant coating is difficult to meet fireproof requirement, meanwhile, tension, crushing resistance that when mobile place uses, cable should possess can not also be met.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tension withstand voltage fire prevention composite flat flexible cable to reach tension resistance to compression and fireproof requirement.
A kind of tension withstand voltage fire prevention composite flat flexible cable in the utility model, comprise inner core, sheath and outer jacket, described inner core comprises at least a branch of conductor, wrapped double-face fireproof mica tape on described conductor, be coated on the refractory mineral matter insulating barrier on described fire-resistant isinglass belt and mild steel tow, described conductor is combined by filament, described conductor and described mild steel tow arranged in parallel and between there is gap, the upper outside of described inner core is extruded with one deck sheath, described sheath fills up the gap between described conductor and described mild steel tow and makes overall in flat, be coated on described sheath and have described outer jacket, described outer jacket comprises the chain armour of copper strips and flexible sheath.Described composite flat flexible cable under normal conditions flame retardant coating itself is a kind of elastic polymer material, there are good insulation property, outside flame retardant coating, extruding one deck refractory mineral matter insulating barrier, when it is when running into high temperature, ensure that circuit is in pyroprocess, not open circuit, not short circuit, nonflammable, there is extraordinary flame-retardant, thus ensure that circuit not power-off in a fire, for escape with rescue fire and provide guarantee, ensure circuit in case of fire unimpeded.Sheath adopts the chain armouring of copper strips to strengthen withstand voltage, the fire protecting performance of cable outward, and outermost layer adopts the soft elastomer sheath that mechanical strength is higher.
Preferably, described filament is the zinc-plated soft copper wire of anaerobic.Described conductor is formed by filament strands, and the lay ratio scope of described conductor is 12 to 14, or described conductor is once restrainted conjunction by filament and formed.
Preferably, the diameter of described filament is 0.1 millimeter to 0.21 millimeter.
Preferably, the outer overlapping wrapped three layers of double-face fireproof mica tape of described conductor, fire-resistance property can reach 1000-1200 degree Celsius.
Preferably, described sheath is made up of high temperature resistant elastomeric material.
Preferably, the steel wire mechanical strength of described mild steel tow is greater than 2000MPa.
Beneficial effect: tension of the present utility model is withstand voltage, and fire prevention composite flat flexible cable improves the anti-withstand voltage fire resistance property of cable in specific field of employment, conductor all adopts zinc-plated soft thin copper wire to increase softness, insulation and outer jacket all adopt high flame retardant refractory material, better to ensure that cable is in high temperature, the safe operation of meeting under extraneous fire condition, cable inner core adds two stone dead wires to ensure the tensile property of cable, the chain armouring of outer jacket copper strips is with reinforced layer, ensure withstand voltage properties and the communication function of cable, greatly improve cable access and communication efficiency.
