B_1级柔性耐火电缆的设计

传统耐火电缆具有耐高温、防爆、耐火(在燃烧中可承受水的喷淋和机械撞击)且载流量大、使用寿命长、一般不需要独立接地导线的特点。B_1级耐火电缆不仅在耐火、燃烧性能指标方面可以与传统耐火电缆相媲美,而且在产品规格多样性、大规模生产效率和安装敷设等方面更具优势。该文对B_1级柔性耐火电缆尺寸结构、工艺材料、性能指标的设计进行详细阐述,保证其在一级公共建筑消防配电系统中安全可靠。

The traditional fire-resistant cable is highly resistant to heat,blast resistant,fire-resistant(Withstand water spray and mechanical impact during combustion),high flow,long life,and generally no need for independent grounding wires.Class B1fire-resistant cable is comparable to traditional fire-resistant cable in fire resistance and combustion performance,It has both advantages in production,installation and laying.The design of the size structure,process material and performance index of class B1 flexible fire-resistant cable is described in detail to ensure its safety and reliability in the fire distribution system of class I public buildings.
