1、交流額定電壓U0/U:300/500V;電纜導(dǎo)體長(zhǎng)期允許zui高工作溫度:聚氯乙烯絕緣分70℃、105 ℃兩種;聚乙烯絕緣為70℃;交聯(lián)聚乙烯絕緣為90℃(絕緣交聯(lián)類型可分為硅烷交聯(lián)和輻照交聯(lián))。
2、zui低環(huán)境溫度:固定敷設(shè)-40 ℃;非固定敷設(shè)-15 ℃。安裝敷設(shè)時(shí)環(huán)境溫度:不低于 0℃。
3 、電纜允許zui小彎曲半徑:金屬帶繞包屏蔽或鋼絲、鋼帶鎧裝電纜不小于電纜外徑的12倍;非鎧裝軟電纜或編織屏蔽電纜不小于電纜外徑的6 倍。
4、導(dǎo)體類型及電阻:如下
導(dǎo)體標(biāo)稱截面 | 導(dǎo)體根數(shù)/單絲直徑mm | 導(dǎo)體根數(shù)/單絲直徑mm | 導(dǎo)體根數(shù)/單絲直徑mm | 20℃時(shí)導(dǎo)體直流電阻Ω/km | 20℃時(shí)導(dǎo)體直流電阻Ω/km |
