Insulated flexible fire-resistant cable

Inorganic mineral insulated flexible fire-resistant cables are mainly composed of copper cores, inorganic insulating materials, inorganic filling materials, metal sheaths and other structures. Besides having excellent electrical conductivity, mechanical and physical properties, and fire resistance, they also have good non-combustibility. This type of cable not only ensures the power supply for fire protection during the fire duration under fire conditions, but also does not spread the fire and does not produce smoke. GB 50016-2014 "Code for Fire Protection Design of Buildings" clearly stipulates that fire protection power distribution lines should be laid separately from other power distribution lines in different cable Wells and trenches. When it is truly difficult to lay them in the same cable well or trench, they should be respectively arranged on both sides of the cable well or trench, and the fire protection power distribution lines should use mineral insulated non-combustible cables. This cable is suitable for power transmission and distribution in elevators, fire control centers, fire protection facilities and densely populated places with an AC voltage of 0.6/1kV and below.

1、U0/U为0.6/1kV。

2、防火性能优越，耐火等级不仅满足国标GB12666.6A类950℃ 90min，还可满足英国BS6387中规定的A级650℃3h、B级750℃3h、C级950℃3h要求。同时，在燃烧中还能耐受水喷与机械撞击。

3、安装时电缆弯曲半径应不小于电缆外径12倍。

4、过载能力大，电缆不仅载流量大，而且具有较大的过载能力。根据布线要求，通常电缆表面温度≤70℃，若布线不可触摸，也不与可燃建筑材料相接触时，电缆护套温度可提高到105 ℃。过载时防火电缆长期工作温度可达250 ℃。
