Instrument current and voltage transformers — technical specifications
Step-down transformers type TSZI
TSZI-1.6, TSZI-2.5, TSZI-4.0- three-phase step-down transformers (transformer windings are made of copper or aluminum) with natural air cooling. Designed to safely power power tools or lamps for local lighting with a frequency of 50 Hz. The transformers are manufactured in accordance with GOST 19294-84 in the climatic version UHL. Heating class — «B». Protective version (in case).
Operating conditions — installation altitude up to 2000 m. Above 1000 m, the nominal power is reduced by 2.5% every 500 m; placement in space — vertical; according to the installation conditions at the workplace, the transformers are stationary.
