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（Um）为10（12）kV的架空电力线路用铜芯、铝芯、铝合金芯交联聚乙烯（XLPE）和高密度聚乙烯（HDPE）绝缘架空电缆。

This product is applicable for aerial power line of AC rated volageU(Um) 10（12）kV copper core, aluminum core, aluminum alloy core crosslinkedpolythylene (XLPE) and high density polyethylene (XLPE) insulation aerialcable.

产品标准Productstandard: GB/T 14049

二、产品使用特点Product Usage Characteristics

1.      额定电压U（Um）为10（12）KV。Rated voltage U(Um) is 10(12) 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℃。Maximum conductor temperature is 250℃ when cable isshorted for less than 5 seconds for XLPE insulated Cable。

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℃。For load-bearing XLPE insulated cable maximum rated temperature ofconductor is 90℃。

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
