A flame retardant cable is a type of cable that can slow down the spread of flames under burning conditions. This kind of cable usually has good flame retardant performance, which can slow down the spread of fire in the event of a fire, so as to effectively protect the safety of the cable and the surrounding environment. This article will introduce the meaning, model, type and characteristics of flame retardant cables.
First, the meaning of flame retardant cable.
A flame retardant cable is a type of cable that can slow down the spread of flames under burning conditions. It usually has good flame retardant properties, which can slow down the spread of fire when it occurs, so as to effectively protect the safety of the cable and the surrounding environment.
Second, the model of flame retardant cable.
The model number of flame retardant cable usually consists of letters and numbers, where the letters represent the flame retardant rating of the cable and the number represents the cross-sectional area of the cable. Common flame retardant cable models are ZR-VV, ZR-YJV, ZR-BV, etc. Among them, ZR stands for flame retardant, VV stands for PVC insulated PVC sheathed power cable, YJV stands for XLPE insulated PVC sheathed power cable, and BV stands for PVC insulated wire.
3. Types of flame retardant cables.
Flame retardant cables can be divided into different types according to different classification methods. According to the different flame retardant grades, flame retardant cables can be divided into three types: low-smoke halogen-free flame retardant cables, ordinary flame retardant cables and fire-resistant flame retardant cables. According to the different occasions of use, flame retardant cables can be divided into two types: flame retardant cables for civil construction and flame retardant cables for industrial use. In addition, according to the different conductor materials, flame retardant cables can also be divided into copper conductor flame retardant cables and aluminum conductor flame retardant cables.
Fourth, the characteristics of flame retardant cables.
Flame retardant cables have the following characteristics:
1.Good flame retardant performance: flame retardant cable can slow down the spread of fire when a fire occurs, and effectively protect the safety of the cable and the surrounding environment.
2.Higher safety: Because the flame retardant cable has good flame retardant performance, it has high safety during use. Even in the event of a fire, it can effectively reduce the damage caused by the fire.
3.Strong adaptability: flame retardant cables have strong adaptability and can be used in different environments. For example, in high temperature, low temperature, humid and other environments, flame retardant cables can maintain good performance.
4.High service life: Flame retardant cables have a high service life due to their good weather resistance and mechanical properties. It can maintain good performance even during long-term use.
5.Lower soot and harmful gas emissions: In the combustion process, the flame retardant cable produces less soot and harmful gases, which is conducive to reducing environmental pollution and harm to the human body.
In short, flame retardant cable is a kind of cable that can slow down the spread of flame under combustion conditions, and has the characteristics of better flame retardant performance, higher safety, strong adaptability, higher service life and lower smoke and harmful gas emissions. In the actual use process, different types of flame retardant cables can be selected according to different needs to effectively protect the safety of the cable and the surrounding environment.
