It sounds like you might be referring to different materials or components, but it's a bit ambiguous. "Fan press" could potentially refer to a device or process related to fans, perhaps for pressing or assembling parts. "Cotton copper wire" could be a type of wire where the conductor is made of copper and is insulated with cotton, though it's not a common or standard insulation material for copper wires.
Could you please provide more context or clarify your question? That way, I can give you a more accurate response. Cotton Possibly insulation or material in a product.
Copper Often used in electrical wiring due to high conductivity.
Fan Could imply a cooling component or mechanical ventilation.
Press Might refer to a pressing machine or mechanical operation.
Wire Likely copper wire, used in electronics or machinery.
