Dry-type transformers are made of high-quality materials and advanced technology, and can be directly installed for use with loads of different natures. Dry-type transformer is divided into SG self-root transformer and SGG isolation transformer two kinds. Self-coupled transformer is a single-turn transformer, used for the utility voltage needs pressure, no safety isolation requirements of the place to use. Isolation transformer is a double winding transformer, in the grid not only has the function of voltage, but also the input winding and output winding in the electrical safety isolation, in order to avoid at the same time touching the electrically charged body (or due to insulation damage and may be electrically charged metal parts) and the place of the danger brought about by the isolation of the grid on the equipment of the three harmonics, protection of the machine generated by the heat and to prevent the reduction of the life of the insulating material, and on a variety of interference Play a certain inhibitory effect.

The product is suitable for AC 50HZ or 60HZ, input/output voltage of 1000V within the low-voltage power distribution, commonly used in various types of imported equipment and electrical equipment requiring special voltage.
