Three-core cable advantages:
Against external damage capability; small footprint, can be laid in various pipe, although more difficult construction, but the overall construction time is short; When installing either climb the tower or into the substation line spacing are more convenient; long-running process even several local metal shield grounding occurs, it will not affect the safe operation of the line.
Cons: cable tray and by its own weight limit, the cable can not do too general, transportation is not convenient; too thick cabling is also more difficult, not easy to bend; three core cable ampacity than the same cross-section of single-core cables smaller.
Single-core cable advantages:
White insulation is easy to protect, less prone to phase short circuit; cable transport more convenient, easier laying; do a relatively long cable tray, under the same section of single-core cable ampacity great.
Disadvantages: not because of their own cable with armored protection, anti-poor capacity external damage; cable root more large area; cable out of the substation, outdoor climbing tower poor layout; unit cost is higher than the three-core cable; especially single core cables in the event of a long-running multi-point grounded metal shield, could easily lead to the circulation, leading cable fever and eventually burned cables.
