Advantages:
1. Have good advantages of good electric performance, high mechanical strength, anti-strong short –circuit ability, strong winding technology and small space of windings etc.
2. We imported the equipment which can wind insulation paper band as more as 32 layers and the total thickness of insulation can be 4.8mm, ranking the first place in the country.
Application:
Used for Transformer with high voltage (110KV - 800KV) and super large capacity
Guarantee:
Invested to the electric and numerical control Model 72 CTC production line for transposed wire from SIEMENS Germany, and implement whole process monitoring
