Oil Type Power transformer 35KV 7.5MVA 7500KVA with OLTC for regulating the voltage in an accurate range. It can be designed from 800KVA to 31500KVA with maximum voltage 35KV and mainly used for power transmission and distribution system like power substation.
TAILI’s oil filled transformer are manufactured in accordance with domestic and international IEC standards according to Customer's market demand.
Â
Â
1. Quality assurance for direct supply of key materials, like core (which made directly from TAILI by high quality cold-rolled silicon steel sheet) and insulation materials (which are strictly selected by our quality control center)
2. Corrugated type tank: automatic welding, zero leakage rate, strong corrosion resistance
3. Positioning device for active-part: free core suspending, maintenance-free, safe and reliable
4. Dedicated automatic winding machine to ensure coil quality
5. Design with multiple shock absorption and noise reduction measures to ensure low operation noise
6. Special structural design and material selection to ensure strong short circuit resistance
7. On load tap changer (OLTC) with independent property rights.
