Implementation of standards：JB2411-79

　　Application: rated voltage 300/500 and below, high-temperature environment, the signal detection. In particular, fire and security systems for the control and power protection circuit transmission line。

　　Operating characteristics: Working temperature: long-term use 200 ℃

　　Short-term use 1000 ℃ 90 minutes

　　Delivery length：

　　Cable is generally to not less than 100 meters, 50 meters above the allow short-term delivery, delivery length of no more than than 10%; measurement error of ≤ 50. If special requirements of both supply and demand can be negotiated。

　　Cable model specification：

　　Example 1 section of 1.0mm2 A class of five-core conductor cable, said high-temperature fire is NHFF 5 × 1.0 (A）

　　Example 2 five core sections 1.0mm2 B steel armor like the conductor shielded cable, said high-temperature fire is NHFP1F22 5 × 1.0 (B）
