Flame Retardant Cable Class B1 is mainly suitable for rated voltage 450/750V and below Power plants, small power tools, instrumentation, power lighting 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.

• nominal voltage: 300/500V, 450/750V
• Long-term working temperature:

• Short-circuit carrying temperature：

• Cable laying temperature: above 0℃.
• The bending radius of the cable:

1. The bending radius of the cable whose OD is less than 25mm shall not be less than 4OD.
2. The bending radius of the cable with OD of 25mm and above shall not be less than 6OD.
3. (OD: The outside diameter of the cable.)

• flame retardant property: The cable meets the requirements of flame retardant B1 level specified in GB/T 31247-2014
