6、敷设条件Installation condition

(1)空气中电缆敷设在阴影处，环境温度为40℃；土壤中电缆直埋深度为700mm,土壤热阻系数为1.0k.m/w，环境温度为25℃。

When cable being laid under shade inair, the ambient temperature is 40℃; If cable is buried in soil depth of1000mm soil thermal resstivity is 1.2km/w, and the ambient temperature is 25℃.

（2）单芯电缆三根水平平行敷设及星形敷设时，中心间距均为一倍电缆外径；多芯为单根敷设。

When three of single core cables laid inparallel and star-laying, the center of the pitch are doubled of the cablediameter; multi-core cable is laid individually.
