  The box-type substation is used for AC 50Hz,10/0.4kV level voltage to transmit electrical energy and change the voltage.

  Box-type substation should include:

  1.All high-voltage power distribution devices in the box

  2.All low-voltage power distribution devices in the box

  3.Power transformer(2 SC-50 dry-type hermetically sealed transformers)

  4.Spare parts,spare parts

  5.Other related facilities and components in the box

  Box-type substation standards:

  (1)GB/T 17467-1988 high-voltage/low-voltage prefabricated substation

  (2)ZBK40001 combined substation

  (3)Technical conditions of SD320 box-type substation

  (4)Rated voltage of GB156 electrical equipment
