Three-phase dry type transformer

product manual  Transformer--Product Overview (MTDG, MTSG single-phase dry-type transformer) MTDG, MTSG series single and three-phase dry type transformers are produced by our company for years using high-quality materials and advanced technology. They have the advantages of moisture-proof and convenient maintenance, and can penetrate into the load center. It can be used in power transmission and distribution sites such as subways, high-rise buildings, airports, stations, terminals, enterprises and tunnels. MTDG, MTSG series single and three-phase dry type transformers are mainly used for various input and output voltages and connection groups of various power supply places and products with AC 50-60Hz and voltage not exceeding 500V. The distribution of tap line capacity can be carefully designed and manufactured according to user requirements.
