光(guang)伏直流電(dian)纜(lan)線(xian)

直(zhi)(zhi)流(liu)(liu)光伏線纜(lan)(lan)用(yong)(yong)(yong)于光伏發電(dian)(dian)系統連接(jie)電(dian)(dian)纜(lan)(lan)，如組串之間(jian)及組串至(zhi)直(zhi)(zhi)流(liu)(liu)配(pei)電(dian)(dian)箱（匯流(liu)(liu)箱）之間(jian)的并聯電(dian)(dian)纜(lan)(lan)，直(zhi)(zhi)流(liu)(liu)側的光伏組件與組件之間(jian)的串聯電(dian)(dian)纜(lan)(lan)、組串之間(jian)及組串直(zhi)(zhi)流(liu)(liu)配(pei)電(dian)(dian)箱（匯流(liu)(liu)箱）之間(jian)的交聯電(dian)(dian)纜(lan)(lan)和直(zhi)(zhi)流(liu)(liu)配(pei)電(dian)(dian)箱至(zhi)逆(ni)變器(qi)之間(jian)的電(dian)(dian)纜(lan)(lan)，也可適用(yong)(yong)(yong)于逆(ni)變器(qi)與輸電(dian)(dian)網(wang)間(jian)連接(jie)用(yong)(yong)(yong)的交流(liu)(liu)應用(yong)(yong)(yong)電(dian)(dian)纜(lan)(lan)。

直流(liu)光(guang)(guang)伏(fu)電(dian)纜(lan)：直流(liu)光(guang)(guang)伏(fu)電(dian)纜(lan)有串(chuan)式和模塊化(hua)兩種。兩者(zhe)都與太(tai)陽(yang)能(neng)電(dian)池(chi)板兼容，并且(qie)可以通(tong)過連接(jie)(jie)負極和正極引(yin)線(xian)將 4 毫米(mi)直流(liu)光(guang)(guang)伏(fu)電(dian)纜(lan)連接(jie)(jie)到逆變器。雖然 4 毫米(mi)光(guang)(guang)伏(fu)電(dian)纜(lan)很受歡迎(ying)，但(dan)也可以使用 6 毫米(mi)和 2.5 毫米(mi)光(guang)(guang)伏(fu)電(dian)纜(lan)。太(tai)陽(yang)能(neng)電(dian)池(chi)板的尺寸決定了應該使用什么光(guang)(guang)伏(fu)電(dian)纜(lan)。
