溝通額外電壓3kV及以下鐵路機車車輛用電纜(電線)
GB 12528-1990 JB/T 8145-1995
一、適用范圍
本產品選用橡皮絕緣,依據絕緣用橡皮的不同分為三個種類,首要適用于溝通額外電壓3kV及以下鐵路機車車輛用電纜的電能傳輸和敷設銜接用線,具有必定的耐油、耐寒、耐紫外線等特性。
二、產品結構示意圖
三、運用特性
1、額外電壓U0/U為500V、750V、1kV、1.5kV和3kV。直流額外電壓為溝通額外電壓的1.5倍。
2、電纜長時間答應工作溫度為: DCXF/2、DCH/3、DCEH/3產品為70℃;DCH/3-100,DCEH/3-100產品為100℃。
3、電纜最低運用環境溫度:DCXF/2、DCH/3、DCEH/3、DCH/3-100、DCEH/3-100等產品應不低于-25℃。
4、電纜敷設的答應曲折半徑:
電纜外徑(D)為20mm及以下時應不小于3D。
電纜外徑(D)為20mm以上時應不小于5D。

五、首要技能特色
1、制品電纜導體直流電阻契合GB/T 3956-1983的有關規定。
2、20℃時絕緣電阻:額外電壓3kV的DCEH/3、DCEH/3-100型電纜應不小于1013Ω.km。
3、制品電纜飽嘗如下溝通電壓實驗不擊穿:
