TZLK (R)-SESH 0,66 kV

General Description

Zero-sequence current transformer TZLK (R)-SESH for 0,66 voltage class. Transformer TZLK (R)-SESH is designed to supply protection circuits for earth-fault protection of individual wires of a three-phase cable and for signal transmission of measuring information to the measuring instruments, automation, signaling and control. TZLK (R)-SESH 0,66 kV have climate version "U", “T” and category 2 according to GOST 15150-69.

Ease of installation of transformers.
The possibility of making a transformer in a detachable execution.
Nomenclature width according to the proposed bus sizes, cable, location of secondary winding.
