Shenxing Cable takes you into the world of fireproof cables: understand common models and applications

In modern society, electricity has penetrated into every corner, providing power for life and work. However, the safety of electricity has always been our focus. With the continuous improvement of the safety requirements for power systems in construction projects, industrial facilities and public places, the importance of fireproof cables has become more and more prominent. Fireproof cables can not only maintain power supply in emergencies such as fires, but also effectively prevent the spread of fire and ensure the safety of personnel. Shenxing Cable is committed to providing high-quality fireproof cables to provide customers with safe and reliable power guarantees.

Analysis of common fireproof cable models

There are many types of fireproof cables, which can be mainly divided into flexible mineral insulated fireproof cables and rigid mineral insulated fireproof cables. According to different needs and application scenarios, the models of fireproof cables are also different. The following are several common fireproof cable models on the market and their characteristics:

BTTZ (heavy copper core copper sheathed magnesium oxide mineral insulated cable)

Features: BTTZ cable has extremely high temperature resistance and fire resistance. It can continue to work for a short time at extreme temperatures up to 1000°C, and is corrosion-resistant, overload-resistant, mechanically strong, and has a long service life. It is suitable for fire protection systems in construction projects.

Letter meaning: B-fixed installation power cable for wiring; T-copper sheath; T-copper conductor; Z-voltage resistance level heavy 750V.

BTTRZ (copper core inorganic mineral insulation tape wrapped insulation copper sheathed flexible fireproof cable)

Features: BTTRZ is a flexible mineral insulated fireproof cable with good bending performance, flame retardancy, and excellent electrical and mechanical properties. Suitable for environments that require flexibility and high safety, such as public buildings and industrial facilities.

Letter meaning: B-fixed installation power cable for wiring; T-copper conductor; T-copper sheath; R-flexibility; Z-voltage resistance level heavy 750V.

BTTVZ (heavy copper core copper sheathed magnesium oxide mineral insulated cable)

Features: BTTVZ cable is made entirely of inorganic materials, with the advantages of fire resistance, high temperature resistance, halogen-free and non-toxic, and can provide long-lasting power transmission in fire. It is suitable for use in high temperature, humid and highly corrosive environments.

Letter meaning: B-Fixed power cable for wiring; T-Copper sheath; T-Copper conductor; V-Polyethylene Y outer sheath; Z-Heavy voltage rating 750V.

BBTRZ (Flexible magnesium hydroxide mineral insulated non-flammable fireproof cable)

Features: BBTRZ cable uses flexible mineral insulation material to make up for the defects of traditional cables such as high hardness and easy combustion, and has higher safety and long-term durability. It performs well in flame retardancy, fire resistance and corrosion resistance.

Letter meaning: B-Fixed power cable for wiring; B-Mineral compound; T-Copper conductor; R-Flexibility; Z-Heavy voltage rating 750V.

NG-A (BTLY) aluminum sheathed flexible isolated fireproof cable

Features: NG-A cable uses aluminum sheath and copper conductor as the main materials, with excellent mechanical resistance, flexible bending performance, high temperature resistance and fire resistance. It is often used in places that require high safety and high temperature resistance, such as fire-prone areas.

Letter meaning: N - fire resistance; G - isolation; A - 950-1000°C; B - mineral insulated cable for wiring; T - copper conductor; L - aluminum metal sheath; Y - polyvinyl chloride outer sheath.

YTTW (flexible fireproof metal sheathed inorganic mineral insulated cable)

Features: YTTW cable can work continuously for more than 3 hours at high temperature, and is suitable for emergency occasions where power is still required during fire. Its inorganic mineral insulation layer gives it excellent fire resistance and long life.

Letter meaning: Y - mica tape metal sheathed mineral insulated cable; T - copper conductor; T - copper sheath; W - inorganic mineral insulation.

Wide application of fireproof cables

Fireproof cables have important applications in modern buildings, industrial facilities, power stations and other fields. They can ensure the continuous operation of the power system when a fire occurs, and buy precious time for personnel evacuation and firefighting. Whether it is a large commercial building, public transportation facility, or a high-risk industrial site, fireproof cables can effectively ensure system safety and avoid greater losses caused by the spread of fire.
