Introduction  A new construction scheme of 110 kV prefabricated cabin substation is proposed which can quickly respond to the needs of rapid station construction in industrial parks and promote the rapid development of urbanization in China.

  Method  A complete set of electrical design method was proposed. Based on the general design experience of substation, the layout scheme of 110 kV substation construction and the selection of electrical equipment were determined according to the characteristics of load nature, load scale and land conditions of industrial park. Form the construction mode of 110 kV substation, including electrical wiring, size and splicing mode of electrical prefabricated cabin.

  Result  According to the load size, grade and land conditions of the industrial park, three classical industrial park construction models are simulated which are mode A, mode B and mode C considering reliability and economy. Three corresponding construction schemes are designed, and technical and economic comparisons are analysed.

  Conclusion  Three typical electrical construction schemes can guide the design of 110 kV substation in industrial park, and have certain popularization significance.
