OIL DUCT STRIP TRANSFORMER OIL DUCT :
We have one pressboard stick (oil duct stick) equipment and 4 sets full-automatic edge fixing lines. Our daily putout is 10000 pcs duct stick to supply. We could provide 500 m oil duct strip one day. 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 paer. Duct strip has the excellent transformer oil impregnation feature, it has high compressive strength more than corrugated pressboard which is the old technology, it's used at high temperature condition and it could be improved the circuit strength.
