Recently, there are many people who pay attention to how to choose armored flame retardant shielded cables, but there are not many people who may really understand.
Armored flame retardant shielded cable is a kind of cable that can effectively prevent the spread of fire, and can be widely used in buildings, ships, coal mines and other places. The following is a brief introduction to the selection, characteristics, construction, principle and application of armored flame retardant shielded cables:
Selection: When choosing an armored flame retardant shielded cable, it is necessary to consider its use, environmental conditions, current to be transmitted, voltage and other factors. According to different needs, select the appropriate cable specifications, number of cores, conductor materials, etc.
Features: The armored flame retardant shielded cable has the characteristics of good flame retardant performance, which can effectively resist the spread of fire and reduce the speed of fire spread. At the same time, it has good electromagnetic shielding and anti-interference performance, which can ensure the stability and reliability of transmission.
Structure: The armored flame retardant shielded cable is composed of a cable core, an armor layer, an electromagnetic shielding layer and a flame retardant outer sheath. The core of the cable is the part that transmits the current and is made up of a conductor and an insulating layer. The armor layer is the part that protects the core of the cable and is usually made of steel wire braiding or steel tape winding. Electromagnetic shielding is a layer that reduces interference and protects signal integrity, and commonly used materials are copper mesh, aluminum foil, etc. The flame-retardant outer sheath is a layer that prevents the spread of fire and is made of flame-retardant materials.
Principle: The flame retardant principle of armored flame retardant shielded cable is through the flame retardant material of the outer sheath, which can effectively delay the spread of flame and prevent the spread of fire in the event of a fire. At the same time, the electromagnetic shielding layer can improve the anti-interference ability of the cable and ensure the quality of transmission.
Application: Armored flame retardant shielded cables are widely used in buildings, ships, coal mines and other places prone to fire. It is often used in fire alarm systems, fire-fighting facilities, emergency evacuation systems and other fields in buildings, which can effectively protect the life safety of personnel. In other places, such as ships and coal mines, it can also reduce the risk of fire to equipment and personnel, and ensure the stability of data and signal transmission.
