A complete transformer substation 35kV is an electrical installation designed to receive, convert (increase or decrease) voltage in an alternating current network and distribute electric energy in power supply systems of consumers in rural, townships, urban, and industrial facilities.
It consists of power transformers, switchgear RU (35; 10; 6; 0.4 kV), automatic control and protection devices.
Complete transformer substations of 35 kV are classified into step-up and step-down.
- Step-up transformer substations (usually constructed at power plants) convert voltage 0.4; 6 or 10kV, generated by generators, at a voltage of 35kV.
- Step-down transformer substations convert the primary voltage of 35kV to secondary 10; 6 or 0.4 kV.
Complete transformer substations are manufactured and delivered to the installation site in fully assembled form or in separate blocks.
By type of design, complete transformer substations (KTP) are divided into:
- Sandwich Panels
- In metal case
By type of RUVN:
- Dead ends
