Type Sc (B) 11-33kv Dry-Type Transformer

The Features of Dry-type Transformers
1. Both the HV and LV windings are surrounded and filled by glass fiber mats, no filler in epoxy resin during casting
Under vacuum condition. The windings will be solidified to form a solid cylindrical overall, with high mechanical
Strength and high reliability and no partial discharge.
2. Fire and explosion proof, do not pollute the environment. Coil winding insulation materials such as glass fiber with
Self-extinguishing properties, and will not arcing when short-circuit happened; Heat the resin will not produce toxic
Or harmful gases.
3. Coil does not absorb moisture, core clamps have a special corrosion protection layer, and transformers can be
Abnormally running in the 93% relative humidity condition. No need special treatment during intermittent service.
4. High short circuit withstanding capability and lightning impulse level.
5. Thin resin in both inner and outer of coil can ensure good heat dissipation. Normally the transformer is air cooling
Type (AN). Force air cooling type (AF) can be used on any transformer, in order to improve short-term overload
Capacity, to ensure safety operation.
6. Lower loss level and save energy can reduce the running cost, and all transformers are maintenance-free.
7. Small size, light weight, small floor space, low cost of installation, no need to consider the discharge of oil, fire and
Other fire control facilities and standby power.
8. Because there is no fire and explosion possibility, it can be easily installed in any place of load center and fully close
To the power consumption equipment, thus reducing the loss on the transmission line.
