Cu/MgO/Cu Mineral Insulated Cable (Heavy Duty 750V 4×4mm²) International

The BTTZ is a premier Heavy-Duty Mineral Insulated Copper Clad (MICC) cable, widely recognized as the ultimate solution for fire-rated electrical circuits. Constructed with high-purity copper conductors, inorganic Magnesium Oxide (MgO) insulation, and a seamless copper sheath, it is entirely non-combustible and maintains circuit integrity at temperatures exceeding 950°C. This waterproof, explosion-proof, and radiation-resistant cable is the gold standard for emergency power systems, fire elevators, and smoke extraction fans in high-rise buildings, airports, hospitals, and historical landmarks. Its robust design eliminates the need for a separate grounding wire and ensures a lifespan exceeding that of the building itself, making it essential for any environment where safety cannot be compromised.
