NALI-SESH 6, 10, 35 kV

The three-phase antiresonant group of instrument transformers NALI-SESH for voltage class 6, 10, 35 kV. The three-phase group of transformers is designed to supply power metering devices, control-measurement apparatus, relay (microprocessor) protection and is also used to monitor insulation in networks up to 35 kV with an isolated or grounded neutral through an arc suppression coil. NALI-SESH 6, 10, 35 kV is installed in switchgear and control gears KRU-SESH. Transformer is manufactured in climate version U, UHL and T, placement category 2 and 1 as per GOST 15150-69.
