One-phase distribution transformers OLS-6,3

One-phase distribution transformers OLS-6,3 (ОЛС-6,3)

Description

Transformers are intended for powering auxiliary networks of sectioning units and automatic load transfer, as well as other  consumers in networks of 6-10 kV and rated frequency of 50 or 60 Hz.

Transformers are manufactured in climatic versions «У» (moderate) or «Т»(tropical) location category 2 according to GOST 15150.

Operating temperatures range from -45°С up to +50°С for the «У2» version and from -10°С up to +50°С for the «Т2» version.

Altitude above sea level no more than 1000 meters.

Operation position - vertical.
