Product Description
Description and feature:
Duct strip is made from high quality pressboard G4 grade. It has excellent transformer oil impregnation feature, high compressive strength more than corrugated pressboard which is the old technology. It is used at high temperature condition and it could be improved the circuit strength.The character are below:
1. High mechanic strength
2. High electric strength
3. Accurate dimension
 
Application:  
Oil duct strip provides duct for the flow of the cooling oil in layer and strip windings in distribution power transformers. It is manufactured by bonding transformer board sticks onto insulating paper or single-coated diamond dotted paper.
Main strips: Rectangular strips, T-strips, Pigeon cauda strips, Abnormity strips.
