Copper Core Copper Sheathed Magnesium Oxide Mineral Insulated Cable (Rigid Fire-Resistant Cable)

BTTZ fireproof cables are widely used in places that require high fireproof performance, such as high-rise buildings, power substations, chemical plants, tunnels, underground facilities, etc. These places have high requirements for cable fireproofing and high temperature resistance. BTTZ cables can maintain stable operation in fire environments and ensure the power supply of key facilities.

BTTZ cables use magnesium oxide (MgO) as an insulation layer, which has extremely high fire resistance and flame retardancy. In the event of a fire, the cable can not only prevent the spread of the fire, but also continue to work for a period of time, providing power support for emergencies, ensuring personnel safety and property protection.

BTTZ fireproof cables use high-purity oxygen-free copper (Oxygen-Free Copper, OFC) as conductors. Oxygen-free copper has excellent conductivity, can effectively reduce power loss, improve cable transmission efficiency, and has extremely strong corrosion resistance to ensure long-term and stable use.

The insulation layer of BTTZ cable is made of high-performance magnesium oxide (MgO), which not only has very good heat resistance, but also effectively prevents cable damage caused by high temperature in fire. Magnesium oxide can provide long-term insulation protection in fire and is one of the most advanced fireproof insulation materials.

The copper tube metal sheath on the outside of BTTZ fireproof cable has extremely high strength and corrosion resistance, which can effectively protect the cable from physical damage, while providing additional electromagnetic shielding, reducing electromagnetic interference and ensuring stable signal transmission.

Yes, BTTZ cable is particularly suitable for high temperature environment. Its magnesium oxide insulation layer and copper tube sheath have good high temperature resistance. Even in a fire environment of up to 950℃, the cable can still maintain basic power transmission functions to ensure safety and reliability.

Yes, BTTZ fireproof cable meets the relevant standards of international fireproof cable. It has passed strict fire resistance tests and can meet the requirements of various countries and regions for fire resistance of power lines, and is suitable for use in various high-risk areas.

The service life of BTTZ cable depends on environmental conditions. Due to the use of oxygen-free copper conductors and copper tube sheaths, and strong corrosion resistance, the service life of the cable under normal conditions can usually reach 20 years or more. Proper installation and maintenance can further extend its service life.

The installation requirements of BTTZ fireproof cable are similar to other types of cables, but due to its metal sheath and heavier material, special attention should be paid to avoid excessive bending and stretching during installation to ensure the integrity of the cable. In addition, contact with sharp objects should be avoided during installation to protect the outer copper tube sheath from damage.

BTTZ cable is mainly used for power lines in power transmission and high-security places, rather than for data and communication lines. If it is needed for communication lines, it is recommended to choose a special communication cable. However, due to its excellent shielding performance, BTTZ cable can play a role in situations where both power and signals are used.
