0.6/1kV XLPE Insulation Power Cabls

Cable type and name

Cable production scope

Cable installing & operating condition

1、The distance between cable centers of singal-core cables laid in parallel: cross-sectional area of corductor≤185mm² 2times of the cable diameter cross-sectional area of conductor≥240mm²; 90mm.

2、Ambient air temperature: 30℃

3、Max.continous operating temperature of conductor: 90℃.

Current carrying rating factors for different ambient air temperature:

Direct in the ground

1、The single-core cables are installed separately, the 

distance between the cable center is 2 times of the cable Diameter.

2、Soil temperature: 25℃

3、Max.continous operating temperature of conductor: 90℃. 4、Thermal resistivity of soil: 1.0℃.m/W.

5、Depth of Direct-Buried: 0.7m

Current carrying rating factors for different soil temperature:

Cable structure & size

Cable technical parameter

Cable carrying capacity

Note: The copper-tape-screen and steel wire of single-core steel wire armorde power cable for AC system must be connected to earth well and effectively.The current

carrying capacity is calculated by formulas of IEC.It is advised in the new edition of GB/T 12706 that the current carrying capacity of steel wire armored power

cable with special structure is lower than that in IEC standard,so the cross-section should be enlarged appropriately.
