    Abstract：The 10（20）kV and 0. 4 kV power supply and distribution for utility tunnels are summarized and contrasted by analyzing and summarizing the current tunnel standards，specifications and collective drawings. Optimization suggestions for high and low voltage power supply and distribution systems are proposed with the case of the utility tunnel power supply and distribution project of Optics Valley Central City，Wuhan.
