The main characteristics of mineral-insulated fire-resistant cables

Mineral-insulated fire-resistant cables feature a flexible design and are primarily made from mineral compounds, effectively addressing the drawbacks of rigid structures—such as their tendency to burn easily and emit toxic fumes. Additionally, these cables offer several advantages that other types of cables lack, including fire resistance, high current-carrying capacity, ability to withstand impulse voltages, resistance to mechanical damage, halogen-free and non-toxic properties, explosion-proof capabilities, waterproof performance, corrosion resistance, extended service life, enhanced safety, overcurrent protection, high-temperature tolerance, and cost-effectiveness.

Introduction to the Fire-Resistant Performance of Mineral-Insulated Fireproof Cables

Among the many mineral-insulated fire-resistant cables, the BTTZ mineral-insulated cable with magnesium oxide insulation undoubtedly boasts exceptional fire performance. The cable features a structure consisting of copper conductors encased in a magnesium oxide insulation layer, all wrapped within a sheath made of pure copper—though the type of sheath can be chosen according to specific needs.

What are the advantages of mineral-insulated fire-resistant cables?

Since all materials used in mineral-insulated fire-resistant cables are inorganic, they possess several advantages that other cables lack. Composed of copper and mineral insulation materials, these cables neither burn nor support combustion, allowing them to continue functioning even under conditions close to flames. Moreover, mineral-insulated fire-resistant cables offer numerous additional benefits.

What are the advantages of mineral-insulated fire-resistant cables?

Mineral-insulated fire-resistant cables sometimes need to be run through iron or plastic conduits. While plastic conduits are prone to aging, iron conduits easily rust. Fire-resistant cables, however, come with copper-aluminum sheaths that eliminate the need for separate conduits, as these sheaths offer excellent corrosion resistance. In addition to superior fire performance, they can also withstand water mist and mechanical impacts during combustion. Importantly, when burned, these cables produce no smoke or toxic fumes, and their insulation material is entirely inorganic.
