IEC推薦的載流量大為降低，截面選擇宜適當放大。
The screen-coppeer-tape and steel wire (including all copper wire for magnetism seperation) of single-core steel wire armored power cable for AC system must be connectted to earth well and effectivity.
The current carying capacity is calculated by formulas of IEC.It is advised in the new edition of GB/T12706 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 appopriately.
