Flexible Fireproof Metal Sheathed Inorganic Mineral Insulated Cable

Cable structure:

Conductor: high-purity oxygen-free copper

Insulation: multi-layer mica tape

Outer sheath: corrugated copper sheath

Rated voltage: UO/U 0.6/1kV

Number of cores: 1, 2, 3, 4, 5, 3+1, 4+1, 3+2

Application Areas:

Fireproof mineral cables are mainly suitable for the following places and applications:

High-rise buildings: especially high-rise buildings, offices, hotels, guesthouses, etc. in large cities. These places have high requirements for the stability and fire resistance of power transmission. Fireproof mineral cables can ensure that the power supply is not cut off when a fire occurs, ensuring the continuous operation of the power system inside the building.

Underground places: such as subways, tunnels, light rails and other crowded environments with strict fire protection requirements. The cable lines in such places must have the ability to ensure normal operation in fires.

Industrial and mining enterprises: such as chemical, metallurgical, electric power and other high-temperature and high-risk industries. Fireproof mineral cables can withstand extremely high temperatures to ensure the stable operation of the power system in harsh environments.

Medical institutions: high-risk places such as hospitals, ensuring that the power supply will not be interrupted in emergencies such as fires, which is helpful for emergency rescue and personnel evacuation.

Cable Structure

Fireproof Cable-YTTW

Features

Excellent fireproof performance:

Meet GB12666.6 and BS6387 standards, can last for 90 minutes at 950°C, and has functions such as mechanical shock resistance and water spray resistance. Suitable for key fire protection application scenarios.

High flexibility and long distance:

The cable has a flexible design, can be coiled for storage, has a small bending radius (≥6-10D), and supports a single continuous length of more than 1000 meters, which is flexible and efficient to install.

Environmental protection and safety:

The insulation material is made of inorganic minerals, which is smokeless, non-toxic and has no secondary pollution, suitable for occasions with high safety and environmental protection requirements. Fireproof cables can maintain normal power supply in a fire environment (950°C for 3 hours).

Durability and economy:

It has corrosion resistance, high temperature resistance, super overload capacity, long life (service life of more than 100 years), and optimized manufacturing and installation processes, which reduces the overall use cost.

Structural Features

YTTW series cables use multi-strand copper strands as conductors, the insulation layer is mechanically wrapped with high-temperature synthetic mica tape, the outer sheath is longitudinally wrapped with copper tape and welded into a tube, and is continuously rolled and corrugated to ensure good sealing and flexibility.

Moisture-proof and sealing performance:

The metal sheath of the cable can achieve sealing protection in a low-smoke and halogen-free environment, avoiding exposure or moisture of the metal sheath, and is suitable for harsh environments.

Want to learn more? Check out our electrical cable most frequently asked questions.

What places are YTTW cables suitable for?

YTTW cable is suitable for places such as subways, tunnels, high-rise buildings, chemical plants, hospitals, etc. that require high fire protection and safety performance, especially crowded or underground environments.

What is the difference between YTTW cable and BTTZ cable?

YTTW cable is more flexible than BTTZ cable, does not require special joints during installation, has lower construction difficulty, and supports longer single lengths. In addition, the flexible structure of YTTW cable can better adapt to complex environments.

At what temperature can YTTW cable operate?

The cable can operate at a continuous operating temperature of 70°C and a short-term overload temperature of 105°C, and can withstand a high temperature of 950°C for 3 hours in a fire environment to ensure continuous power supply.

What is the environmental performance of YTTW cable?

This cable uses inorganic mineral insulation material, which is non-toxic and smokeless. It will not produce harmful gases or secondary pollution when burning. It is an environmentally friendly green product.

How long is the service life of YTTW cable?

The cable is designed to have a service life of more than 100 years, and has excellent corrosion resistance, suitable for long-term use in harsh environments.

How much current can YTTW cable withstand?

The single-core cable can carry up to 630mm², and the multi-core cable can reach 70mm². It has a strong current carrying capacity and can meet high power requirements.

What should be paid attention to when installing YTTW cable?

During installation, it is necessary to ensure that the bending radius is not less than 6-10 times the outer diameter of the cable, and to avoid cracking of the weld during construction. It is recommended to be operated by professionals.

What is the cost-effectiveness of YTTW cable?

Although the initial investment is high, due to its long service life and simplified installation and maintenance process, the overall comprehensive cost is more advantageous than traditional cables.
