1 Temperature field and ampacity of underground cables in steady and transient conditions buried in complicated soil are studied.

2 The cable ampacity in one circuit decreases with the load increase of another adjacent circuit.

3 Please note that ampacity may be reduced by ampacity of terminals or connectors.

4 Ampacity is the safe current-carrying capacity of an electrical conductor in amperes as defined by code.

5 Conductor is tube type, lower skin effect, larger ampacity of unit cross-sectional area.

6 Ampacity Ampacity is the safe current-carrying capacity of an electrical conductor in amperes as defined by code.

7 Note: the ampacity provided here are only the ampacities of B1, D, E, F and G. The ampacities of other laying method can be calculated according to above table through conversion.

8 Finite element method is applied to solve the field with the temperature field characteristic, then the ampacity of buried cables is received after iterative computation.

9 The impact law of different influencing factors on cable ampacity is obtained by case simulation, demonstrating the correctness and reliability of the model.

10 Aluminum Conductor Composite Core is a brand new conductor for overhead lines. Its advantages are light weight, high strength, good thermal stability, low sag,[] large ampacity and corrosion resistance.

11 It is not recommended to use bracket for the protective conduit. The ampacity in bracket is the calculation data of the author which only for reference.

12 The applications of underground cables in urban power grid are increasingly widespread, and the research on cables ampacity is more important.

13 Available to meet specific mounting and cooling requirements, packaging and higher than standard ampacity ratings.

14 AC resistance of cable conductor is an important factor to calculate the ampacity of cable bundles, and proximity effect factor is an important parameter to affect AC resistance.

15 Finally, the development of research and application of cables ampacity online monitoring are presented.
