　　Isolation Transformer Description:

　　Isolation Transformers

　　DG, SG series of single, three phase dry type transformer is our company for

　　many years in high-quality materials and advanced process technology and production,

　　with fire, moisture, safety and reliability, save energy and maintenance advantages

　　of convenience, to look deep into the load center can be used subway, high-rise buildings,

　　airports, railway stations, docks, tunnels, power transmission and distribution businesses

　　and places.

　　DG, SG series of single, three phase dry type transformers, mainly for the exchange of

　　50-60Hz, voltage not exceeding 1000V supply a variety of places, products of various

　　input and output voltage, join groups, tap line group capacity allocation, can be

　　designed according to user requirements and manufacturing.
