1、額定電壓U0/U為300/500V;電纜導體的長期工作溫度:聚氯乙烯絕緣為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))。敷設(shè)電纜時的環(huán)境溫度不低于0℃。電纜允許在環(huán)境溫度-40~50℃,相對濕度不大于80%時作固定敷設(shè)或移動使用。
1. The rated voltage U0/U is 300/500V; the long-term operating temperature of the cable conductor is 70 ℃ and 105 ℃ for polyvinyl chloride insulation, 70 ℃ for polyethylene insulation, and 90 ℃ for cross-linked polyethylene insulation (insulation cross-linking types can be divided into silane cross-linking and irradiation cross-linking). The ambient temperature during cable laying shall not be lower than 0 ℃. Cables are allowed to be fixedly laid or moved for use in environments with temperatures ranging from -40 to 50 ℃ and relative humidity not exceeding 80%.
2、敷設(shè)安裝電纜時的***小彎曲半徑:無鎧裝層的電纜,應(yīng)不小于電纜外徑的6倍,有鎧裝結(jié)構(gòu)的電纜,應(yīng)不小于電纜外徑的12倍,有屏蔽層結(jié)構(gòu)的軟電纜,應(yīng)不小于電纜外徑的10倍。
2. The minimum bending radius for laying and installing cables: for cables without armor layer, it should not be less than 6 times the outer diameter of the cable; for cables with armor structure, it should not be less than 12 times the outer diameter of the cable; for flexible cables with shielding layer structure, it should not be less than 10 times the outer diameter of the cable.
