11KV/33KV 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

11kv/33kv dry-type transformers are widely used in medium voltage power distribution systems. 11kv transformers are usually used for urban power distribution, and 33kv are used for industrial high voltage. Due to the advantages of oil-free fire prevention, low loss, and green environmental protection, dry-type transformers are widely used in high-rise buildings, underground substations, data centers and other places with strict fire protection requirements.

图标 Product Advantage

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.
