In normal operation, the maximum temperature of XLPE insulated control cable conductor is 90 ℃, and that of PVC insulated control cable conductor is 70 ℃.

3.2          短路時（最長持續(xù)5秒），交聯(lián)聚乙烯絕緣控制電纜導(dǎo)體最高溫度為250℃，聚氯乙烯絕緣控制電纜導(dǎo)體最高溫度為160℃。

In case of short circuit (lasting for 5 seconds at most), the maximum temperature of XLPE insulated control cable conductor is 250 ℃, and that of PVC insulated control cable conductor is 160 ℃.

3.3          電纜敷設(shè)不受落差限制，敷設(shè)時環(huán)境溫度不應(yīng)低于0℃。

The cable laying is not limited by the drop, and the ambient temperature should not be lower than 0 ℃.

3.4          敷設(shè)時電纜的最小彎曲半徑：交聯(lián)聚乙烯絕緣控制電纜無鎧裝時不小于8D, 聚氯乙烯絕緣控制電纜無鎧裝時不小于6D，有鎧裝或銅帶屏蔽時不小于12D，有屏蔽層的軟電纜時不小于6D（D為電纜外徑）

Minimum bending radius of cable during laying: not less than 8D for XLPE insulated control cable without armor, not less than 6D for PVC insulated control cable without armor, not less than 12D for armored or copper tape shielded cable, not less than 6D for flexible cable with shielding layer (D is the outer diameter of cable)
