220kv-230kv Low Noise Power Transformer NINGBO TIANAN (GROUP) CO., LTD.
Â
1. Product standards
   >>GB1094.1 ~ 2-1996.
   >>GB1094.3, 5-1985.
   >>GB/T6451-1995.
   >>IEC76.
2. Low loss
- Optimization of electromagnetic calculations, using combined technology of electrical shielding andÂ
 magnetic circuit, effectively controlled leakage, so as to reduce the load loss and to avoid partial Â
 overheating.
- Use high quality cold-rolled lattice orientation high permeability silicon steel, to reduce the load loss,Â
 no-load current.
- Core all-helical stacking with STEP joints, and advanced stacking process, reduced the load loss, load  Â
 current and electromagnetic noise.
3. Low partial discharge
To ensure the safe and steady operation of the transformer under continuous rated voltage, our Electric Power Research Institute conducted a lot of research to develop a more reasonable insulation structure, plus the strict technology specifications and technical staff experience, ensured the low partial discharge of our products.
4. High strength
- Adoption of six-side method positioning for the body, meets the transportation requirements of, horizontal acceleration not more than 0.3G, vertical direction not greater than 0.15g.
- Upper and Lower Clamps and the formation of tight fixed side beam frame.
- The tank can withstand the vacuum test and required positive pressure test.
5. Low Noise
- Use of high-quality core silicon steel;
- Core STEP stepping joints;
- Reduction of the flux density, despite of the increase of cost;
- Use low-noise fan as the air cooling equipment;
- Increase the shock absorbing measures;
- Well interior-protection, to avoid direct rigid contact of the body and tank;
6. Maintenance-free
Our company adopts the domestic leading technology, use fully enclosed structure for the transformer tank, ensuring product life of 30 years, and maintenance-free operation.
