2. Consisting of 5-71 strands
3. Equipments imported from SIMENS
4. Competitive price
Advantages:
1. Have good advantages of good electric performance, highmechanical strength, anti-strong short –circuit ability, strongwinding technology and small space of windings etc.
2. We imported the equipment which can wind insulation paperband as more as 32 layers and the total thickness of insulation canbe 4.8mm, ranking the first place in the country.
Application:
Used for Transformer with high voltage (110KV - 800KV) and superlarge capacity
Guarantee:
Invested to the electric and numerical control Model 72 CTCproduction line for transposed wire from SIEMENS Germany, andimplement whole process monitoring
