广州南洋电缆有限公司JKLGYJ-0.6/1KV-70/10架空绝缘导线Aerial insulatedcables

一、产品特点及用途Product features and uses

本产品适用于交流额定电压U为1KV及以下架空电力线路用铜芯、铝芯、铝合金芯耐候型聚氯乙烯、聚乙烯和交联聚乙烯绝缘架空电缆。

This product is applicable for AC rated volage U(Um) of 1kVand below aerial power line that needs copper core, aluminum core, aluminumalloy core weather proof PVC, PE and polyethylene (XLPE) insulation aerialcable.

产品标准Product standards: GB/T 12527

二、产品使用特点Product Usage Characteristics

1、  额定电压U（Um）为1（1.2）KV。Ratedvoltage U(Um) is 1 (1.2) Kv。

电缆可用于单相接地故障时间每次一般不大于1min的系统，亦可用于最长每次不超过8h，每年累计不超过125h的系统。

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

2、  电缆敷设温度应不低于-20℃。Ambienttmperature should be not lower than -20℃ when cable isinstalled.

3、  短路时（最长持续时间不超过5S）交联聚乙烯绝缘电缆的最高温度：电缆的导体温度250℃。短路时（最长持续时间不超过5S）聚氯乙烯绝缘或聚乙烯绝缘电缆的最高温度：电缆的导体温度160℃。Maximum conductor temperature is 250℃ when cable isshorted for less than 5 seconds for XLPE insulated Cable. And for PVC or PEinsulated Cable, the maximum conductor temperature is 160℃ when cableis shorted for less than 5s。

4、电缆导体的最高长期允许工作温度：（对有承载结构的电缆）交联聚乙烯绝缘90℃，而对于聚氯乙烯绝缘或聚烯烃绝缘的架空电缆长期允许工作温度为70℃。For load-bearing XLPE insulated cable maximum rated temperature ofconductor is 90℃. And for load-bearing PVC or PE insulated cable maximum ratedtemperature of conductor is 70℃。

5、电缆敷设后的弯曲半径应不小于以下规定Minimumbending radius is as follows when cable is installed:

单芯电缆——20(D+d)±5%mm  For single-core cable-20(D+d), ±5%mm.

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

(D,d 分别为电缆外径与导体的标称直径，单位为：mm)

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