20KV Cast Resin Dry Type Power/Distribution Transformer

Brand Name:TSTY

Model Number: SCB11、SCB13、SCB14

Phase: Three

Service Voltage: 6.6-35kV

Rated Capacity: 30-5000kVA

20kv is a medium voltage distribution voltage level between the traditional 10kv and 35kv. 20kv dry-type transformers are suitable for users with large power consumption, such as large factories, commercial centers, etc. Dry-type transformers are cast with insulating resin, with high safety, maintenance-free, environmental protection and other characteristics, and are widely used in places with high safety requirements.

Product Design Features

 

1. The most advanced epoxy resin casting process in China is adopted, which has good insulation performance;

2. The new cold-pressed oriented silicon steel sheet is used as the iron core, and the seven-step 45-degree full-bevel joint has beautiful craftsmanship, and the no-load loss is reduced by 3-5% percentage points compared with the three-step;

3. In the traditional dry-type transformer production, the insulating paint of the iron core is mostly black or black, while TSTY uses transparent insulating paint, which can intuitively see the process and materials.

4. The core bending clamp is designed independently, with a simple structure, convenient manufacturing and installation, and greatly reduced operating noise.

Dry Transformer Features

 

1. High safety: It is cast with epoxy resin and has excellent fireproof performance. There is no risk of oil leakage, and the waste disposal is relatively simple and environmentally friendly.

2. Flexible installation: It can be installed directly inside the building, close to the power load center, greatly shortening the low-voltage power supply distance. It is light in weight, has small basic weighing requirements, and has no directional restrictions for installation.

3. Maintenance-free: There is no need to regularly check the oil quality and oil level, and there is no need to replace the transformer oil and seals.

4. Good heat dissipation and overload capacity. The winding has a large thermal capacity and strong short-term overload capacity. The forced air cooling design can significantly increase the output capacity in a short time.
