Product Description
Description and function:
Duct strip is created from higher high quality pressboard G4 grade. It has exceptional transformer oil impregnation feature, large compressive toughness more than corrugated pressboard which is the outdated technology. It is employed at large temperature situation and it could be enhanced the circuit toughness.The character are beneath:
one. Higher mechanic power
2. High electric strength
3. Exact dimension
Oil duct strip provides duct for the stream of the cooling oil in layer and strip windings in distribution electrical power transformers. It is created by bonding transformer board sticks on to insulating paper or single-coated diamond dotted paper.
Principal strips: Rectangular strips, T-strips, Pigeon cauda strips, Abnormity strips.
