Product Description
Dry-type transformer means that the iron core and winding are not immersed in insulating oil.
It is mainly composed of a silicon steel sheet made of an iron core and a coil cast by epoxy resin.
An insulating cylinder is placed between the high and low voltage coils to increase electrical insulation, and the coils are supported and restrained by pads. The overlapping fasteners of its components are all anti-loosening. Transformers such as mechanical equipment, in the power system, general steam turbine transformers, boiler transformers, ash removal transformers, dust removal transformers, desulfurization transformers are all dry-type transformers, the transformation ratio is 6000V/400V and 10KV/400V, used for rated voltage 380V load.

8. Heat dissipation method: natural air cooling or temperature-controlled automatic heat dissipation;
9. Noise coefficient: ≤30dB
Cooling methods:
| Natural Air Cooling | Forced Ail Cooling |
| the transformer can operate continuously for a long time at rated capacity | the output capacity of the transformer can be increased by 50%, which is suitable for intermittent overload operation or emergency overload operation;due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operating state, so it should not Keep it in continuous overload operation for a long time |
Structural performance:
1.Solid insulation encapsulated winding
2.Unencapsulated winding: among the two windings, the higher voltage is the high-voltage winding, and the lower voltage is the low-voltage winding. From the relative position of high and low voltage windings, high voltage can be divided into concentric type and overlapping type. Concentric winding is simple and easy to manufacture, and all adopt this structure. Overlapping type, mainly used for special transformers.
Advantages:
1. Safe, fireproof, non-polluting, and can be run directly in the load center;
2. Adopting domestic advanced technology, it has high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life;
3. Low loss, low noise, obvious energy saving effect, maintenance-free;
4. Good heat dissipation performance, strong overload capacity, and can increase capacity operation when forced air cooling;
5. Good moisture-proof performance, suitable for operation in high humidity and other harsh environments;
6. Dry-type transformers can be equipped with complete temperature detection and protection systems. Adopting an intelligent signal temperature control system, it can automatically detect and display the respective operating temperatures of the three-phase windings. It can automatically start and stop the fan, and has alarm, trip and other function settings;
7. Small size, light weight, less space occupied and low installation cost.
Dry type transformers are widely used in local lighting, electronic circuits,high-rise buildings, airports, terminals, CNC machinery and equipment, etc.
