Fire-Resistant Cable

2. Applications

This cable may prevent human from being suffocated by toxic gas generated from accidental burning of cable. They are suitable for use in the circumstance demanding strict fire-resistance and environmental-protecting, such as high-rise buildings, hospitals, subways and shopping malls etc

3. Operating characteristics:

a. Max long-time working temperature of conductor should not exceed 70^oC;

b. The ambient temperature under installation should not be less than 0^oC.

c. For the diameter < 25mm, min bending radius should not be less than 8 times outer diameter; for the diameter≥25mm, min bending radius should not be less than 12 times outer diameter.

The fire resistance characteristics and testing methods of the finished electric wire conform to the GB 12666.9.: it cannot be broken down under the burning flame with 950-1000or 750-800 at rated voltage. Also, the cable can work for 90min, or more at the firing temperature of 800. The product can continuously work for 5 minutes without broken by the 3.5kv voltage testing.
