One-phase distribution transformers OL (ОЛ) on powers of 2,5 and 4 kVAOne-phase distribution transformers OL (ОЛ) on powers of 2,5 and 4 kVA
The transformers are intended for powering circuits of sectionalization units and units of automatic switch of reserve (AVR), as well as for powering other instrument in electric mains for voltage class 6-10 kV with 50 or 60 Hz frequency. Transformers are manufactured in climatic versions "YHL" (temperate outside mounting) or "T" (tropical) according to the standard requirements of GOST 15150 location category 1. Ambient air temperature during operation period should be from minus 60°С up to plus 50°С for "YHL1" version and from minus 10°C up to plus 50°С for "T" version. Altitude above sea level is not higher than 1000 m. Creepage distance III as to GOST 9920. Mounting in vertical position. The transformer is patented Table 1. Technical data
