    本產品適用于交流額定電壓(U0/U)450/750V及一次啊的電器儀表、配電裝置的信號傳輸、控制和測量系統??蓮V泛應用于冶金、電力、石油、化工等各種領域。

    This product is suitable for the signal transmission, control and measurement system of electrical instruments and power distribution devices with AC rated voltage (U0/U) 450/750V and one-time. It can be widely used in various fields such as metallurgy, electric power, petroleum and chemical industry.

    使用特性Use characteristics

    1、電纜額定電壓U0/U:450/750V

    Rated cable voltage U0/U: 450/750V

    U0-電纜設計用的導體對地域金屬屏蔽之間的額定工頻電壓;

    U0-The rated power frequency voltage between the conductor used in the cable design and the regional metal shield

    U-電纜設計用的導體間的額定工頻電壓;

    U- rated power frequency voltage between conductors used in cable design;

    2、電纜正常運行時導體很高工作溫度:交聯聚乙烯絕緣為90℃;聚氯乙烯絕緣為70℃。

    The maximum working temperature of the conductor during the normal operation of the cable: 90°C for cross-linked polyethylene insulation; 70°C for polyvinyl chloride insulation.

    3、電纜短路時導體很高溫度:交聯聚乙烯絕緣為250℃;聚氯乙烯絕緣為160℃(短路很長持續時間為5秒)。

    The maximum temperature of the conductor when the cable is short-circuited: 250°C for cross-linked polyethylene insulation; 160°C for polyvinyl chloride insulation (the longest short-circuit duration is 5 seconds).

    4、電纜安裝時很小彎曲半徑:

    Minimum bending radius during cable installation:

    有鎧裝或繞包屏蔽結構的電纜應不小于電纜外徑的12倍;

    Cables with armored or wrapped shielding structure should not be less than 12 times the outer diameter of the cable;

    其余結構電纜應不小于電纜外徑的6倍。

    Other structural cables should not be less than 6 times the outer diameter of the cable.

    5、電纜的很低允許敷設溫度:敷設時電纜溫度不低于0℃,環境溫度低于0℃時,應對電纜進行預熱。

    The minimum allowable laying temperature of the cable: the temperature of the cable shall not be lower than 0℃ during laying, and the cable should be preheated when the ambient temperature is lower than 0℃.

    6、電纜絕緣電阻:很高額定溫度時。體積電阻率r不低于1012Ω.cm;絕緣電阻常數Ki不小于36.7MΩ.km。Cable insulation resistance: at the highest rated temperature. The volume resistivity r is not less than 1012Ω.cm; the insulation resistance constant Ki is not less than 36.7MΩ.km.
