Current-conducting wires of TZK and TZKR types, enclosed, with common sheathing for phases, circular-formed

Current-conducting wires, enclosed, circular, with common sheathing for phases with inter-phase dividing partitions (or without it) are designed for electrical connections in circuits of three-phase alternating current with the frequency of 50 Hz and 60 Hz, voltage up to 10 kV of power plant auxiliaries.

Current-conducting wires of 6 kV to 15 kV are designed to perform electrical connections of main circuit of generator, step-up generator transformer for TPP, GRES, HPP and in generator exciter’s circuits.
