目前国内外生产防火电缆结构主要有：一是发明于上世纪90年代的MI型矿物绝缘电缆（即ＢＴＴ耐火铜管布线），另一种是耐火云母绕包高分子绝缘材料包覆耐火电缆（NH型）；再一种是防火铝管隔离套型（NG型）防火电缆。这些结构的电缆存在的主要问题有：MI型矿物绝缘电缆采用铜护套，首先是用铜量大增，生产成本增加；再者采用铜管拉拔技术工艺复杂，设备投入高；另外难以实现大长度段生产，并且特别硬，敷设安装、接头都比较麻烦等；NH型耐火电缆虽工艺简单，成本较低，但在750℃-800℃火焰下的安全可靠性不及MI型电缆稳定，击穿率很高，不能用于安全能要求较高的场所；NG型防火电缆由于采用铝套，铝的熔点只有660℃，所以耐火温度也不能太高，并且柔韧度较差，安装不方便。 At present, the main structures of fire-resistant cables produced at home and abroad are: one is the MI-type mineral insulated cable (that is, BTT fire-resistant copper tube wiring) invented in the 1990s, and the other is fire-resistant mica wrapped polymer insulation material-coated fire-resistant cable ( NH type); another is the fireproof aluminum tube isolation sleeve type (NG type) fireproof cable. The main problems of cables with these structures are: MI-type mineral insulated cables use copper sheaths, first of all, the amount of copper used is greatly increased, and the production cost is increased; moreover, the copper tube drawing technology is complicated and the equipment investment is high; in addition, it is difficult to realize It is produced in long lengths, and it is very hard, and it is troublesome to lay and install and connect; although the NH type fire-resistant cable is simple in process and low in cost, its safety and reliability under 750°C-800°C flames are not as stable as MI type cables. The wear rate is very high, so it cannot be used in places with high safety requirements; NG type fireproof cables use aluminum sheaths, and the melting point of aluminum is only 660°C, so the fire resistance temperature should not be too high, and the flexibility is poor, which is inconvenient to install.
为了解决目前各类防火耐火电缆存在的问题，提高产品的安全性，使用性，能够使产品的安全防火等级达到MI型电缆的标准，其生产工艺类似普通电缆的生产，急需研究开发一种生产工艺简单，任意长度段生产，规格多样，并具有高强度很好的柔韧性，安装敷设方便等特点的电缆。 In order to solve the problems existing in various types of fire-resistant and fire-resistant cables, improve the safety and usability of the products, and make the safety and fire-proof grades of the products reach the standards of MI-type cables, its production process is similar to that of ordinary cables, and it is urgent to research and develop a production method. The process is simple, it can be produced in arbitrary lengths, with various specifications, and has the characteristics of high strength, good flexibility, and convenient installation and laying.
