使用特性：
1）電(dian)線的交(jiao)(jiao)流(liu)額(e)定(ding)電(dian)壓(ya)(ya)(ya)(ya)(ya)U0/U（相電(dian)壓(ya)(ya)(ya)(ya)(ya)/線電(dian)壓(ya)(ya)(ya)(ya)(ya)）為(wei)300/500V。當使(shi)用于交(jiao)(jiao)流(liu)系統(tong)時(shi)，額(e)定(ding)電(dian)壓(ya)(ya)(ya)(ya)(ya)至少應(ying)等于該(gai)系統(tong)的標稱電(dian)壓(ya)(ya)(ya)(ya)(ya)，系統(tong)的工(gong)作(zuo)電(dian)壓(ya)(ya)(ya)(ya)(ya)允許(xu)超(chao)過標稱電(dian)壓(ya)(ya)(ya)(ya)(ya)的10%。
2）電線的(de)長期工作溫度應(ying)不(bu)超過70°C。
3）電線適用于在水中長期工作。水的PH值應為6.5～8.5。水壓一般不超過1.0N/mm2。
