Sgbdgb series dry-type, isolating, voltage transformer dry-type auto-transformer product overview sgb (dgb) series three-phase (single-phase) dry-type, isolating, voltage transformer is a multi-coil (double coil and above) structure voltage transformer, the primary and secondary windings are insulated from each other. Its transformation ratios are of fixed and tapping type, which enable voltage bucking and boosting. It can also electrically isolate input and output windings from each other to avoid risks of simultaneous access to electrified body (or electrified metal parts due to insulation damage) and ground hazard. Besides, it also has certain inhibiting effect of various kinds of interference. Main functions of sgb (dgb) series three-phase (single-phase) dry-type, isolating, voltage transformer: 1. Electrical safety isolation 2. Adjustment of voltage class 3. Overcome center drift, and improve power supplying balance 4. Anti-surge and wave-filtering applicable occasions sgb (dgb) series three-phase (single-phase) dry-type, isolating, voltage transformer is mainly used in power supply places with ac 50-60hz, with an input supply voltage does not less than1140v (ac), such as buildings, airports, railway stations, docks, enterprises, tunnels and all other power transmission and distribution places which frequently require to change voltage class and security isolation. Rated input voltage, rated output voltage, join groups, tap winding capacity allocation can all be designed and manufactured according to user requirements. Sgb (dgb) series three-phase (single-phase), dry-type, isolating, voltage transformer should be used indoors, and the normal operating conditions are: 1. Ambient temperature: -15- + 45 2. Altitude:

Szb.dzb series dry-type auto-transformer dry-type auto-transformer product overview szb (dzb) series three- phase dry-type auto-transformers are single-coil type transformer. Its primary and secondary sides share a winding, and the transformation ratios are of fixed and adjustable types, voltage buckling and boosting can be realized. Compared to isolation transformer of the same capacity, auto-transformer has advantages of material-saving, simple structure, small size, light weight and high efficiency. It is particularly economical when the transformation ratio aligns to the occasion. However, due to the sharing of winding between the primary and secondary sides, the initial stage has electrical contact, which shall be considered in some occasions. The main role of dry-type, auto-transformer is to change the voltage class. Applicable occasions szb (dzb) series three- phase (single-phase) dry-type auto-transformers are widely used in high-speed rail, subway, high-rise buildings, airports, railway stations, docks, corporate and tunnels and all other power transmission and distribution places requiring to change voltage class. Szb.dzb series dry-type auto-transformershould be used indoors, and the normal operating conditions are: 1. Ambient temperature: -15- + 45 2. Altitude:
