At the same time, support racks are installed under the arrester, disconnectors, current and voltage transformers (if they are provided by the project), as well as rod lightning rods. After installing the devices on the portal and the support piles, linear disconnectors are regulated and they carry out the whole busbar of the open part, including descents to high-voltage apparatuses. The flexible wires of the buses are connected by special branching clamps. At the end of the installation of the transformer substation, tighten all bolted connections.

After the installation of the transformer substation is completed, start-up and commissioning works are carried out, which are carried out by specialized teams. All works on installation, adjustment of the transformer and secondary switching circuits are made with the appropriate acts and protocols. This documentation, together with the technical documentation and the instructions of the manufacturing plants of the complete equipment, will be transferred to the operating organization.

Complete transformer substations of consumers are equipped with small power transformers (250-630 kVA), so they can be delivered to the installation site by motor vehicles in fully assembled condition (without a transformer). Consider the sequence and rules of installation of such substations using the example of a complete transformer substation of KTPP type.
