產(chǎn)品標準Productstandard: GB/T 14049

二、產(chǎn)品使用特點(diǎn)Product Usage Characteristics

1.      額定電壓U（Um）為10（12）KV。Rated voltage U(Um) is 10(12) Kv。

電纜可用于單相接地故障時(shí)間每次一般不大于1min的系統，亦可用于最長(cháng)每次不超過(guò)8h，每年累計不超過(guò)125h的系統。

Cables can be used for those systems of single-phrase groundfault time generally not more than 1 min each time, and maximum not more than 8hours, accumulatively not more than 125 hours per year.

2. 電纜敷設溫度應不低于-20℃。Ambienttmperature should be not lower than -20℃ when cable isinstalled.

3. 短路時(shí)（最長(cháng)持續時(shí)間不超過(guò)5S）交聯(lián)聚乙烯絕緣電纜的最高溫度：電纜的導體溫度250℃。Maximum conductor temperature is 250℃ when cable isshorted for less than 5 seconds for XLPE insulated Cable。

4. 電纜導體的最高長(cháng)期允許工作溫度：（對有承載結構的電纜）交聯(lián)聚乙烯絕緣90℃。For load-bearing XLPE insulated cable maximum rated temperature ofconductor is 90℃。

5. 電纜敷設后的彎曲半徑應不小于以下規定Minimumbending radius is as follows when cable is installed:

單芯電纜——20(D+d)±5%mm  For single-core cable-20(D+d), ±5%mm.

多芯電纜——15(D+d)±5%mm  For multi-core cable-15(D+d), ±5%mm.

(D,d 分別為電纜外徑與導體的標稱(chēng)直徑，單位為：mm)

Note: D denotes the overall diameter ofcable, while d means the diameter of the conductor, unit:mullimeter
