Product Description:
Polyimide film sintering wire is made by copper or aluminum conductor. At first wrapped polyimide film which is coated with adhesive material on the conductor, and sintered film and film, film and conductor together. 
   The polyimide film wire is uniformly wrapped around the polyimide film or polyimide fluorine 4.6 composite film on the copper (aluminum) conductor. After heating, the fluorine 4.6 on the composite film is melted, so that the film and the conductor are bonded as a whole. This product has excellent voltage resistance, thin insulation thickness and heat resistance up to 220 ºC. It is mainly used for windings of motors, reactors, welding machines or other similar electrical products. The electrical bare copper (aluminum) wire produced by extrusion process is an ideal material for producing polyimide film clad wire.
Polyimide film is coated with a high temperature resistant binder and coated with a polyimide film strip. After heating, the thin film band becomes a continuous insulating layer. The winding wire has high temperature, low temperature and radiation resistance, the sealing, electrical and wear resistance. It is applied to steel rolling motor high temperature operation, traction motor, deep well pump motor and dry Transformer coil.
   For Aromatic polyimide tape-covered aluminum magnet wire, after the aluminum magnet wire is taped with a tape that is 1.5 mm thick with 1.0 mm of this thickness being polyimide film and the remaining 0.5 mm being fluoroplastic, it is heated and heat-sealed.
   Aromatic polyimide tape-covered aluminum magnet wire has a higher space factor than that of glass-fiber covered aluminum magnet wire and fully satisfy class-H heat resistance requirements. When Aromatic polyimide tape-covered aluminum magnet wire is used as substitute for these glass-fiber covered aluminum magnet wire, electrical equipment can be expected to be reduced in size and weight. Aromatic polyimide tape-covered aluminum magnet wire has electrical characteristics and coating flexibility far superior to those of glass-fiber covered aluminum magnet wire. Aromatic polyimide tape-covered aluminum magnet wire is primarily used for electric motors in vehicles, large direct current machines, and dry transformers. However, the aluminum magnet wire is more costly than other winding aluminum magnet wires. It is recommended, therefore, to use them when, there are problems in terms of space factor in particular. The aluminum magnet wire is inferior to glass-fiber covered aluminum magnet wire in corona resistance. When using the aluminum magnet wire in high-pressure equipment, special consideration must be given to insulation design.
 
Breakdown voltage of polyimide film covered copper/aluminum wire:

Wrapping method	Insulation thickness   mm		Breakdown voltage ≥
	Nominal value	Tolerance
Two layers polyimide self-locking wrapping	0.15	±0.03	6000
Two layers of polyimide lap wrapped in opposite directions	0.15	±0.03	6000
Three layers of polyimide lap wrapped in opposite directions	0.23	±0.03	7000

Polyimide film aluminum wire is a multi-layer polyimide & fluoropolymer dispersion-coated film. The fluoropolymer coating functions as a heat-fusible layer for bonding to magnet wire conductors. It has superior scrape abrasion resistance and exhibits lower frictional properties than wire insulated with other commonly used polyimide materials.  Polyimide film aluminum wire is ideal for demanding magnet wire applications and for difficult-to-wind motors.
