35KV Grade Epoxy Resin Cast Dry Type Transformer SC(B)10-30~2500

35KV Grade Epoxy Resin Cast Dry Type Transformer SC(B)10-30~2500

Epoxy resin cast dry type transformers are mainly composed of silicone wafers of iron core and epoxy resin pouring coils, high and low voltage coils between the placement of insulation barrels to increase electrical insulation, and by the pad support and

Product Details

Form of Epoxy resin cast dry type transformer:

1. Open type of epoxy resin cast dry type transformer: is a commonly used form, its body and the atmosphere in direct contact, adapted to a relatively dry and clean room, (the ambient temperature of 20 degrees, relative humidity should not exceed 85%), generally there is air self-cooling and air cooling two cooling ways.

2. Closed of epoxy resin cast dry type transformer: the device is located in a closed shell, and the atmosphere does not directly contact (due to the sealing, poor cooling conditions, mainly used for mining, is explosion-proof type).

3. Pouring type of epoxy resin cast dry type transformer: with epoxy resin or other resin pouring as the main insulation, it is simple structure, small size, suitable for smaller capacity transformers.

Structural Features of Epoxy resin cast dry type transformer:

Because the epoxy resin cast dry type transformer has the advantages of strong short-circuit resistance, small maintenance work, high operating efficiency, small size and low noise, it is often used in fire prevention, explosion-proof and other places with high performance requirements. 

1. Safety, fire prevention, no pollution, can be directly run in the load center;

2. The use of advanced domestic technology, high mechanical strength, strong ability to resist short-circuit, small partial discharge, good thermal stability, high reliability, long service life;

3. Low loss, low noise, energy saving effect of epoxy resin cast dry type transformer is obvious, maintenance-free;

4. Good thermal performance, strong over-load capacity, forced air cooling can improve capacity operation;

5. Good moisture-proof performance, adapt to high humidity and other harsh environment operation;

6. Dry transformers can be equipped with a perfect temperature detection and protection system. Using intelligent signal temperature control system, the operating temperature of the three-phase winding can be automatically detected and displayed, the fan can be automatically started and stopped, and the functions of alarm, tripping and other functions can be set;

7. Small size, light weight, less footprint, low installation costs of epoxy resin cast dry type transformer.
