低煙低鹵電纜在正常使用時,導(dǎo)體長期允許工作溫度不超過70℃,短路時(短路時間5S),導(dǎo)體溫度不超過160℃;
電纜敷設(shè)的溫度為0℃敷設(shè)時最小彎曲半徑,無鎧裝層時應(yīng)不小于電纜外徑的10倍,有鎧裝層時應(yīng)不小電纜外徑的15倍。
For normal use of halogen free low-smoke cable, the permittedlongtime operating temp. of conductor is 90℃;For short circuit(the longest time is 5s), the.temp of conductor max should notexceed 250c.
For normal use of low-halogen low-smoke cable,the permitted long-time oper-ating temp.of conductor shouldnot exceed 70℃;For short cincuit(the longest time is 5s), temp,of conductor max should not exceed 160℃
The lowest temp forthe laying of cables is o℃ .As for the shortest bend cadius: Forcables without sheath,it should not be shorter than,10 times of outer diam;For cables with sheath; it should not beshort than 15times of outer diam.
