DG, SG single three-phase dry type transformer

Overview

DG and SG series single and three-phase dry-type transformers have the advantages of moisture-proof and convenient maintenance. They can be used in the load center and can be used in power transmission and distribution places such as subways, high-rise buildings, airports, stations, terminals, enterprises and tunnels.

DG, SG series single and three-phase dry type transformers are mainly used for the distribution of various input, output voltage, connection group and tap line capacity of various power supply places and products with AC 50-60Hz and voltage not exceeding 500V. Can be carefully designed and manufactured according to user requirements.
