It combines the functions of transformer step-down and low-voltage distribution organically and installs them in a steel structure box that is moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof and theft-proof. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation. Box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution room and distribution station and becomes a new type of complete set of transformer and distribution equipment.

[0003] The sound insulation and noise reduction device of the box-type substation mainly refers to the box-type shell of the box-type substation. This box-type shell is located outside the substation equipment and can cover the substation equipment.
