交流额定电压3kV及以下铁路机车车辆用电缆(电线)
GB 12528-1990 JB/T 8145-1995
一、适用范围
本产品采用橡皮绝缘,根据绝缘用橡皮的不同分为三个品种,主要适用于交流额定电压3kV及以下铁路机车车辆用电缆的电能传输和敷设连接用线,具有一定的耐油、耐寒、耐紫外线等特性。
二、产品结构示意图
三、使用特性
1、额定电压U0/U为500V、750V、1kV、1.5kV和3kV。直流额定电压为交流额定电压的1.5倍。
2、电缆长期允许工作温度为: DCXF/2、DCH/3、DCEH/3产品为70℃;DCH/3-100,DCEH/3-100产品为100℃。
3、电缆最低使用环境温度:DCXF/2、DCH/3、DCEH/3、DCH/3-100、DCEH/3-100等产品应不低于-25℃。
4、电缆敷设的允许弯曲半径:
电缆外径(D)为20mm及以下时应不小于3D。
电缆外径(D)为20mm以上时应不小于5D。
