Rigid Fire Resistant Cable - BTTZ

Rated voltage 750V and below mineral insulated cables are used in nuclear power plants, metallurgy, chemical industry, mines, kiln manufacturing, and other hazardous, severe, and high-temperature environments. In recent years, they have also been increasingly applied in high-rise buildings, airports, harbors, subway systems, and other locations to ensure the continuous operation of fire pumps, fire elevators, local lighting, emergency evacuation signage, security surveillance, fire prevention and smoke exhaust systems, and self-generated power sources during fires. As the cables are composed entirely of inorganic materials, they do not cause fires and cannot burn or support combustion. With copper having a melting point of 1083°C and magnesium oxide having a melting point of 2800°C, these cables can maintain power supply even in fires approaching the melting point of copper, demonstrating excellent fire resistance.
