Modular package transformer substations for 20-220 kV

Modular package transformer substations of KTPB series are designed to receive, convert, and distribute three-phase alternating-current electric power with 50 Hz frequency and rated voltages of 10(6), 20, 27.5, 35, 110, and 220 kV.

The modular package transformer substations KTPB are used:

  1. at the 35, 110, and 220 kV sides of grid substations; 
  2. for power supply to mining enterprises;  
  3. for power supply to oil and gas fields; 
  4. for power supply to industrial consumers; 
  5. for power supply to traction substations;
  6. for power supply to utility users;
  7. for power supply to large-scale construction projects;
  8. for power supply to rural areas; 
  9. at power plants (as applicable); 
  10. and at many other projects.

Modular package transformer substations of 27.5, 35, 110, and 220 kV have the following characteristic features that allow minimizing expenditures for the entire service life of the products:

  1. The substations safely operate by any standard electric connection diagrams existing in the country; also, orders are taken for diagrams different from standard ones.  
  2. Step-by-step expansion and development from simple to more complex diagrams is possible without additional reconstruction works and interruption in power supply to consumers. 
  3. The substations are completed with high-voltage equipment through the whole range of the equipment manufactured in CIS and other foreign countries, including ABB, Siemens companies, etc.  
  4. Short mounting time due to the simplicity and compactness of the unit constructions with installed auxiliary circuits and due to the availability of enlarged units ready for mounting.
  5. Commissioning of the project within a very short time.
  6. In 35 kV mobile substations, usage of sledges as the foundation and as short-distance conveying equipment allows quick on-site mounting of the substation and quick changing its mounting location.

* 35/10(6) kV (P)KTPB series mobile modular package transformer substation: its design provides for the installation of high-voltage equipment without reinforced concrete components.

** 110 kV KTPB (small-sized) series modular package transformer substation: the bay framework is 7500 mm and less in width because of the use of disconnectors with central rotating columns.

*** KTPB series modular package transformer substation allows utilizing transformer capacity that is different from the given.

KTPB series modular package transformer substations of 220, 110, 35, 27.5, and 20 kV allow using circuits different from standard ones.

The layout of 220, 110, and 35 kV KTPB series substations, viz. arrangement of their components, takes due account of the design features of all types of used electric equipment as well as the requirements for expansion flexibility of the outdoor switchgear and use of up-to-date means of mechanization at every stage of the construction and operation of substations.

Seismic stability is 9 points according to the MSK-64 scale.

With respect to its technical parameters, the equipment complies with the latest IEC and GOST standards.

Made in accordance with the Corporate Standard Ts 00212883-061:2014.
