What Are The Models Of Resin Type Transformer?

Dry-type resin type transformers refer to transformers whose iron cores and windings are not immersed in insulating oil. Generally, they are cooled by natural cold air and forced cold air.

There are many classification methods of dry-type transformers. The following are some common classification methods of dry-type transformers.

Dry-type resin type transformers are available in the following models:

1. According to the voltage level: 1000KV, 750KV, 500KV, 330KV, 220KV, 110KV, 66KV, 35KV, 20KV, 10KV, 6KV, 0.66KV, 0.38KV, 0.22KV, etc.

2. According to the insulation and heat dissipation medium: dry-type transformers, oil-immersed transformers, among which dry-type transformers are further divided into: SCB epoxy resin cast dry-type transformers and SGB10 non-encapsulated H-class insulation dry-type transformers.

3. According to the iron core structure material: silicon steel laminated transformer, silicon steel coiled iron core transformer, amorphous alloy iron core transformer.

4. According to the design energy-saving sequence: SG, SJ, S7, S9, S11, S13, S15.

5. According to the number of phases: single-phase transformer, three-phase transformer.

6. According to the capacity, the rated capacity of the transformer is 3KVA, 5KVA, 10KVA, 15KVA, 20KVA, 25KVA, 30KVA, 40KVA, 50KVA, 80KVA, 100KVA, 125KVA, 160KVA, 200KVA, 250KVA, 315KVA, 400KVA, 500KVA, 630KVA , 800KVA, 1000KVA, 1250KVA, 1600KVA, 2000KVA, 2500KVA, 3150KVA, 4000KVA, 5000KVA, etc.

Generally, dry-type resin type transformers are mainly used in indoor or combined box-type substations, such as local lighting, high-rise buildings, airports, and terminal CNC machinery and equipment.
