Block-modular buildings NPP E'KRA BNKU, ZRU, etc.

Buildings with a frequency control system of the BMZ with SDR are designed to accommodate the following equipment:

• devices and systems for soft-start and speed control of electric motors with voltage 3...15 kV;
• frequency converters of the ESN series for an average voltage of 3...10 kV AC with a capacity of up to 12.5 MW.

The buildings of block low-voltage complete BNKU devices are designed to control, protect, alarm, receive and distribute three-phase alternating current of industrial frequency 50 or 60 Hz in the power supply networks of industrial, oil and gas producing and processing enterprises.

Complete transformer substations of KTP with a voltage of 6(10)/0.4 kV are designed for receiving, converting and distributing electrical energy of three-phase alternating current with a frequency of 50 and 60 Hz.

Closed switchgears in modular block buildings are designed for receiving and distributing electrical energy from three-phase alternating current with a frequency of 50 Hz and a voltage of 6 (10, 35) kV.

The general substation control points of the OPU are designed to ensure the uninterrupted operation of facilities for the transmission and distribution of electric energy. Substation equipment for auxiliary relay protection, automation and control circuits, high-frequency communication and telemechanics equipment is installed in the OPU building.

Models: BNKU, KTP, ZRU, OPU.
