Research on Connection Schemes for 10 kV Underground Cable Between Main Grid and Distribution Network

  Introduction  In order to avoid poor connection of 10 kV underground cable between main grid and distribution network because of the influence of slope.

  Method  Aiming at the 1.2 m × 1.2 m cable trench commonly used in the South China Power Grid， this article set a clear principle of comparison， and through analysis and comparison of various schemes.

  Result  A set of solution schemes were formulated for different topography and supporting conditions.

  Conclusion  The solution schemes enables the cable of distribution network project to connect smoothly into substation through cable trench， and solves the problem of poor connection between the main grid and distribution network of 10 kV underground cable.This schemes can be solidified in the standardization work to form part of the standard design scheme.
