四、使用特性ApplicatIon Features
- 額定電壓U（Um）為1（1.2）KV。Rated voltage U(Um) is 1 (1.2) 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 ground fault time generally not more than 1 min each time, and maximum not more than 8 hours, accumulatively not more than 125 hours per year.
- 電纜敷設溫度應不低于-20℃。Ambient tmperature should be not lower than -20℃ when cable is installed.
- 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℃。短路時(shí)（最長(cháng)持續時(shí)間不超過(guò)5S）聚氯乙烯絕緣或聚乙烯絕緣電纜的最高溫度：電纜的導體溫度160℃。Maximum conductor temperature is 250℃ when cable is shorted for less than 5 seconds for XLPE insulated Cable. And for PVC or PE insulated Cable, the maximum conductor temperature is 160℃ when cable is shorted for less than 5s。
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℃，而對于聚氯乙烯絕緣或聚烯烴絕緣的架空電纜長(cháng)期允許工作溫度為70℃。For load-bearing XLPE insulated cable maximum rated temperature of conductor is 90℃. And for load-bearing PVC or PE insulated cable maximum rated temperature of conductor is 70℃。
5、電纜敷設后的彎曲半徑應不小于以下規定Minimum bending 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 of cable, while d means the diameter of the conductor, unit:mullimeter
五、產(chǎn)品規格Product Specification
型號Type | 芯數Number of cores | 標稱(chēng)截面Nominal cross-section mm2 |
JKYJ | 1 | 16~400 |
