Abstract
The utility model discloses an improved flexible fireproof cable, including a cable core, the cable core form by the transposition of three insulation core, the mineral fiber filling layer is filled by the department in the cable core clearance, around the double -deck alkali -free glass fiber tape of package outside the cable core, crowded package tao kaiization low smoke and zero halogen separates the oxygen layer between double -deck alkali -free glass fiber tape, at outer alkali -free glass fiber tape plus establish aluminium strip lock armo separation sleeve, outmost crowded packet of tao kaiization low smoke halogen free outer sheath at the cable core. The utility model discloses the insulating tao kaiization of cable silica gel reaches around band solidification with packing under high temperature to and form tao kaiization polyolefin hot setting protective layer at the ectonexine of lock armo aluminium strip, thereby avoid flame direct to the aluminium strip contact, this kind of distinctive flame retardant coating forms powerful protection to the cable core, thus reach than with the better fireproof effect of traditional fireproof cable.
Description
Technical field
The utility model relates to field of cable technology, is specially a kind of improved flexible fireproof cable.
Background technology
Existing general fireproof cable and flexible fire-proof cable adopt mineral insulation, copper sheath reaches relevant fire performance.But shortcoming clearly: general fireproof cable takes mineral insulation filling, copper sheath drawing extension process, its technique is quite complicated, and production length limits by copper pipe length, install with annex very complicated, mineral insulation ratio is easier to moisture absorption, will prevent mineral insulation from making moist completely and cause insulation property to reduce even short circuit during production and construction.Flexible fire-proof cable is that insulating barrier adopts after ribbon, and after breaking out of fire, in cable, ribbon will pulverize powder, and this powder is easy to come off thus causes cable core to touch phase with core, core and copper sheath.Two is that sheath adopts copper strips vertical bag welding embossing.(embossing) will be hardening after generation mechanical deformation for copper strips, thus cause this cable not recover the flexibility of copper strips by annealing.Also easy because of a variety of causes generation weld defect during vertical bag welding, affect the performance of copper sheath.Equally also to prevent insulation moisture absorption from making moist during production and construction completely and cause decreasing insulating.
Utility model content
The purpose of this utility model is to provide a kind of improved flexible fireproof cable, solves in prior art easy moisture absorption of insulating and causes decreasing insulating, copper sheath not to bend and the problem such as copper strips welding embossing defect.
For achieving the above object, a kind of improved flexible fireproof cable described in the utility model, comprises cable core, and described cable core forms by three insulated wire cores are stranded; At cable core gap location filling mineral fiber-filled layer; At the outer wrapped double-deck alkali-free glass fiber band of cable core, between double-deck alkali-free glass fiber band, extrude Tao Kaiization low smoke and zero halogen oxygen barrier layer, outside outer field alkali-free glass fiber band, add aluminium strip lock armo separation sleeve; Tao Kaiization low smoke and zero halogen oversheath is extruded at the outermost layer of cable core.
Further improvement, described insulated wire cores by copper conductor, be extruded in gold mica tape outside copper conductor and wrapped Tao Kai SiClx rubber insulation outside gold mica tape is formed.
Further improvement, described Tao Kaiization low smoke and zero halogen oxygen barrier layer is Tao Kaiization low-smoke halogen-free polyolefin oxygen barrier layer.
Further improvement, described Tao Kaiization low smoke and zero halogen oversheath is Tao Kaiization low-smoke halogen-free polyolefin oversheath.
Compared with prior art, the beneficial effects of the utility model are:
1, by improving silicon rubber, directly extrude as insulation with modified silica-gel, under high temperature, Tao Kaiization solves the problem that raw-material moisture absorption causes decreasing insulating.
2, use aluminium strip lock armo, internal layer squeezes Tao Kaiization polyolefin oxygen barrier, and the outer Tao Kaiization polyolefin oversheath that squeezes replaces copper sheath or copper strips welding embossing, reaches better flexible and economy.
3, at high temperature cable silicone insulation Tao Kaiization and fill and twining package tape solidification; and form Tao Kaiization polyolefin hot setting protective layer at the ectonexine of lock armo aluminium strip; thus avoid flame directly to contact aluminium strip; this distinctive fireprotection layer forms powerful protection to cable core, thus reaches than flameproof effect better with traditional fireproof cable.
4, because aluminium strip lock armo cost is far smaller than the cost of copper sheath (on the basis of armouring same thickness, aluminum ratio copper saves the cost of 90.89%), COMPREHENSIVE CALCULATING, whole fireproof cable become instinct reduce reach 30-50%, economic benefit and social benefit fairly obvious.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of improved flexible fireproof cable described in the utility model, comprises cable core, and described cable core forms by three insulated wire cores are stranded; At cable core gap location filling mineral fiber-filled layer 4; At the outer wrapped double-deck alkali-free glass fiber band 5 of cable core, between double-deck alkali-free glass fiber band 5, extrude Tao Kaiization low smoke and zero halogen oxygen barrier layer 6, outside outer field alkali-free glass fiber band 5, add aluminium strip lock armo separation sleeve 7; Tao Kaiization low smoke and zero halogen oversheath 8 is extruded at the outermost layer of cable core.
Described insulated wire cores by copper conductor 1, be extruded in gold mica tape 2 outside copper conductor 1 and wrapped Tao Kai SiClx rubber insulation 3 outside gold mica tape 2 is formed.
Described Tao Kaiization low smoke and zero halogen oxygen barrier layer 6 is Tao Kaiization low-smoke halogen-free polyolefin oxygen barrier layer.
Described Tao Kaiization low smoke and zero halogen oversheath 8 is Tao Kaiization low-smoke halogen-free polyolefin oversheath.
This programme insulation adopts conventional rubber cover extruder to extrude, simple and convenient, the basis of the existing equipment of factory, expressing technique and personnel just can realize, and speed of production and production efficiency is produced higher than traditional fireproof cable far away.Owing to solving the problem of insulation moisture absorption, thus strict waterproof wiring terminal need not be adopted when high-temperature baking operation and installation when saving production, install very easy, the instrument of extremely specialty and professional need not be needed to install as traditional fireproof cable, greatly improve production and installation effectiveness.By using aluminium strip lock armo, internal layer squeezes Tao Kaiization polyolefin oxygen barrier, the outer Tao Kaiization polyolefin oversheath that squeezes forms while distinctive fireprotection layer replaces copper sheath or copper strips welding embossing to reach traditional flameproof effect, and aluminium strip lock armo technique welds the simple many of embossing more than the copper sheath drawing process of traditional fireproof cable and copper strips.Ectonexine sheath also only needs conventional extruder and routine techniques technique just can realize.Greatly improve production efficiency.Due to aluminium strip lock armo cost be far smaller than copper sheath cost (on the basis of armouring same thickness, aluminum ratio copper save 90.89% cost; Note: according to existing copper valency 40 yuan/kg, aluminium valency 12 yuan/kg calculates), COMPREHENSIVE CALCULATING, whole fireproof cable becomes instinct to reduce to reach 30-50%, economic benefit and social benefit fairly obvious.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
