Rigid fire-resistant cable - BTTZ
Category:
Fire-Resistant Cable
Product Description
Mineral-insulated cables with a rated voltage of 750V or less are used in nuclear power plants, metallurgy, chemical, mining, and kiln industries, and other hazardous, harsh, and high-temperature environments. In recent years, they have also been increasingly used in high-rise buildings, airports, docks, and subways to ensure the uninterrupted operation of fire pumps, fire elevators, local lighting, emergency evacuation instructions, security monitoring, fire prevention and exhaust systems, and backup power supplies and other fire-fighting electrical equipment and important equipment in case of fire. Because the cables are entirely composed of inorganic materials, they themselves cannot cause fires, and cannot burn or support combustion. Since the melting point of copper is 1083℃ and the melting point of magnesium oxide is 2800℃, this type of cable can continue to supply power in fire conditions close to the melting point of copper, exhibiting excellent fire-resistant performance.
