double side)≤0.40 mm
1, Film Sintering wire is widely used in high voltage, high power
windings or high temperature and high humidity environment for it’s
good quality, such as thinner insulation layer, higher broken
voltage, better flexibility of conductor, better water repellency
and so on.
2, If the corona resistance film is used, the corona resistance,
surge voltage resistance and heat dissipation capacity will be
increased. This is used for variable frequency motor, traction
motor and high voltage motor.
3, Film-backed mica tape polyimide film lapped wire and film-backed
mica tape polyimide film sintered wire have good performance of
corrosion resistant, corona resistant, water resistant and heat
resistant. They are used on wind power generator windings.

4, The copper conductor is made from high quality oxygen free
copper rod with oxygen content less than 20 ppm, so the electric
conductivity is more than 100% after annealing. The aluminum
conductor is made from high quality aluminum rod, the electric
conductivity is more than 62% after annealing.
5, All our compound insulation winding wires are type tested,
routine tested and sample tested in accordance with NBT 31048-2014
and customer standards.
1, high voltage, high power motor windings.
2, the motor windings in high temperature and high humidity
3, the corona resistance films is used for variable frequency
motor, traction motor and high voltage motor.
4, wind power generator windings.
1, We use the horizontal umerically controlled tiny pressure
thermal cycling annealing furnace which obtains 7 national
intellectual property patents to anneal copper wires. It can
provide a uniform temperature and vacuum environment which
effectively prevents the oxidation of copper wires and get copper
wires with uniform performances.
2, The sintering and wrapping machines are made in Lukas Germany.
It have high production efficiency because of double lapping and
dual takeup. The wires are wrapped flat and have excellent

3, Our company has a great team of professional and technical
personnel and high-quality production workers. So we have mature
technology process and strong product development capability.
Moreover, we have strict management system and improving the
4, Our production environment is very clean by sealing the plant.
Each channel is provided with an air shower door. We supervise and
control the production environment by LPC-301 type laser dust
particle counter according to the international standards of
cleanliness class less than ISO7. So the film-wrapped sintered
windings have excellent insulation properties.
