EPOXY COATING
|
The craft paper or presspaper is machine coated on one/both
sides with required thickness of epoxy resin. The ‘B’ stage
coating process is to be maintained. Then while final usage,
this becomes tack-free at 110°c-130°c and gets bonded.
ADVANTAGES
• Safe tolerance of axial and mechanical forces.
• Internal strengthening of coils.
• Helps in faster drying & filling as the liquid insulating
agent penetrates the pressboard insulation completely in
a short period.
• Minimised danger of partial discharges.
APPLICATION
Gardicot is used in gas / oil insulated transformers for
electrical insulation and coil strengthening. The uncoated
portions enable quick evacuation of air & moisture.
AVAILABILITY
Gardicot composites are available in various thicknesses in
rolls & narrow widths on request.
QUALITY
CONTROL
At our works quality control is top priority. Polycom's
laminates are manufactured with the help of the latest
