Complete single-transformer KTPB and two-transformer 2KTPB substations in an insulated shell with a capacity of 160 … 4000 kV • A with or without inputs from an emergency power source, with protection and automation, performed on microprocessor units, are intended for:

  • reception of three-phase alternating current with a frequency of 50 Hz for a voltage of 6 (10) kV;
  • transformation and distribution of electricity at a voltage of 6 (10) / 0.4 kV;
  • automating the transition to a backup or emergency power supply in case of loss of the main power supply and automatic return to power from the main sources when the voltage is restored.

Structurally, KTPB and 2KTPB consist of one or several blocks and is a metal container in which sandwich panels are used as enclosing structures, inside which there is a power transformer (oil sealed or dry), high-voltage and low-voltage panels, as well as auxiliary equipment.
KTPB and 2KTPB provide complete safety for the environment and for maintenance personnel during operational work, and have an attractive aesthetic appearance. The design of KTPB and 2KTPB has a high degree of reliability and facilitates quick installation and start-up on site.
