In recent years, fires in public buildings have become increasingly frequent. While causing significant economic losses, they are often accompanied by casualties. The primary cause of casualties in fires is the release of large amounts of toxic gases and smoke. Therefore, fire-resistant control cables have become increasingly popular in enclosed spaces where large crowds gather, such as subways, hotels, and exhibition halls. So, what are the characteristics of fire-resistant control cables? Let's find out.
What are the uses of fire-resistant control cables?
1. Product standards: GB3210HL07-98, GB9330-88, Q/3210HL06-98, GB12706-91, GB12666, IEC60331-1999, GA306.2-2001.
2. Applications: This product has high fire resistance and can maintain safe operation for a certain period of time under flame conditions. It is suitable for use in high-rise buildings, oil fields, telephone plants, power plants, mines, chemical plants, subways, and other applications requiring high fire protection. It is also an ideal cable for emergency power supply, fire protection, elevators, and communication signal systems.

Note: We can design and produce fully flame-retardant and fire-resistant power and control cables, cross-linked polyethylene insulated fire-resistant control and power cables, and halogen-free fire-resistant power and control cables according to user requirements.
Performance:
Long-term allowable operating temperature of the conductor: 70°C for PVC and 90°C for XLPE.
The cable installation and laying temperature must not be lower than 0°C.
The cable's fire resistance characteristics comply with IEC60331-1999.
For armored cables, the bending radius should be no less than 12 times the cable's outer diameter; for unarmored cables, it should be no less than 6 or 8 times the cable's outer diameter.
The above is the explanation of fire-resistant control cable. Fire-resistant control cable has high fire resistance. Within a certain period of time, it will not short-circuit or short-circuit failure when directly burned by flames. Therefore, it is helpful to reduce losses when a fire occurs. When it comes to fire problems, it is necessary to remind you that for our personal safety, we must pay attention to electrical safety. When buying wires, do not buy products without 3C certification.
