The manufacture of a magnetic circuit with an oblique joint made it possible to bring the efficiency of the transformer idling to 25% ~ 27%. On transformers of the TM type, flat oil cooling radiators produced in Iran are used, on transformers of the TMG type, corrugated pipes made in Turkey are used. High-quality transformer steel produced by Novolipetsk Metal Works (Russia) is used for the manufacture of magnetic circuits. Special attention is paid to the quality of products, the introduction of new energy-saving materials, the introduction of modern high-tech components that allow us to operate our products for a very long period without repair.All products manufactured at the enterprise are certified by the State Standard bodies of the Republic and have certificates of conformity, international quality certificate ISO 9001:2015, as well as a positive conclusion from the National Energy-saving Company "NEK".The company is a member of the Uzeltehsanoat Association. Currently, along with the production of high-voltage equipment, we have started the production of Circuit breakers from 20A to 250A using South Korean technology, which were not previously produced in our republic.The production enterprise "ELSTAN" was organized in 2003 and is located at the address: Tashkent region, Chirchik, Tiklanish str. 1-A on the former territory of the Chirchik branch of the All-Union Institute of Transformer Engineering.The main activity of the enterprise is the production of electrical products such as power transformers 6, 10, 35, 110, 220 kV type TM, TMG. Current transformers, voltage transformers 6, 10, 35, 110, 220kV. Complete transformer substations such as KTPP, GKTP, KTPS, KTPM, PKTPN, KTPB high-voltage cells of KRUN, KRV type K-59, K-47, CSR cameras, disconnectors such as RLND, RVZ, RVFZ, RDZ, VNRU, Circuit breakers of the ELS 253 series from 20 to 250A and much more.
