• 450/750V Flame Retardant Control Cable Class B1 is mainly suitable for rated voltage 450/750V and below control and protection lines and other applications. It can be widely used in places with relatively dense populations and high flame retardant combustion levels requirements, such as subways, airports, hospitals, super high-rise buildings, large shopping malls, hotels, museums, exhibition centers, and transportation hubs, and other places.

PS:

• According to the requirements of the customer can use irradiation crosslinking.
• Flame-retardant(anti-flaming): This indicator focuses on the spread of flame when the cable burns.
• Fire-proof: This indicator focuses on the connection of a circuit at a fixed time when the cable burns.
