11kv 22kv 33kv Dry Type Epoxy Resin Distribution Transformer

The dry type transformer has following insulation classes: class B, class F, class H, class

C, etc. Their thermal-endurance temperature is respectively 130C, 155C, 180C, and 220C.

As adopting new material and new technology of Depont, the model SG(B) dry type transformer

has reached class H of thermal endurance, and some of its key location reached class C of the

thermal endurance.Model SG(B) new products are dry transformer with the highest safety in

current market. All of its insulating materials are of non-combustion supporting, self-extinguishing,

nontoxic one. It shows advantages especially when used in those fields where high safety is required,

humidity and temperature are high, and ventilation is poor,such as in power sites,underground

railways, ships, chemical and metallurgical sites. Outer casing and blower fan cab be provided

if required by users.The coil of model SG(B) is specially designed and made of special material

with special technological process, which renders the product excellent moisture-proof,

mildew-proof and salty fog-proof performances, much higher temperature endurance,and

mechanical performances during its entire service life.Model SG(B) adopts new structure,

novel material and up-to-date technology, featuring good heat-sinking capability, long thermal

endurance, strong overload capability, it can run stably under stably under 120% rated load for

a long period. It can keep a long-term running under full-load in IP23 environment without

forced air ventilation necessary.
