Dry-type instrument transformers ТСЗИ-1,2

Instrument transformers Transformers of the ТС(З)И 1,6-4,0 У2 series are designed to supply power tools in 50 Hz AC networks. In the type designation structure of ТС(З)И – Х –У2 transformers: Type designation structure: Т - three-phase; С - dry-type; З - protected (enclosed) design; И - for supplying power tools; Х - rated power, kVA; У2 - climatic version and placement category; The transformers comply with the requirements of ГОСТ 11677-85. The transformers are operated under the following conditions: rated values of environmental climatic factors in accordance with ГОСТ 15150 and ГОСТ 15543.1; non-explosive environment free of conductive dust and of aggressive vapours and gases that destroy metals; no exposure to snow dust. Operating conditions: Degree of protection IP 00 (IP 11) in accordance with ГОСТ 14234. Duty – continuous. Ambient temperature from -45˚C to +40˚C. Relative air humidity not more than 80% at 25˚C. Rated frequency-50 Hz Winding connection diagram and vector group У/У (Д)-0 (12) Altitude not more than 1000 m above sea level; Operating position of the transformer – vertical.
