ResinColorBrownUsageIt is also known as DDP. The use of this
B-stage resin coated paper increases the short circuit strength of
distribution transformer coils. It is produced by coating modified
epoxy resin in diamond dot patterns on electrical insulating paper.
The size of the dots are carefully designed to avoid interfering
with vacuum drying and oil impregnation. This type of presspaper is
treated chemically and included nitrogen content to get a upgraded
thermo performance.FeatureDiamond dotted insulation paper has
better dielectric properties and better mechanical properties than
normal DDP paper after heat solidification. DDP diamond dotted
insulation paper for transformer ddp insulating
paperAdvantageDiamond Dotted Paper insulating paper is an
insulating material which is coated with special modified epoxy
resin in diamond-shaped shape on electrical insulating paper. It is
widely used in interlayer insulation and turn insulation of
oil-immersed power transformer. Because the resin coating of the
diamond lattice adhesive insulating paper is point-like, it ensures
the immersion of oil and the discharge of gas in the insulating
material, effectively avoids corona and local discharge, and thus
ensures the safety and reliability of the insulation
structure. Sample provide1. We send sample A4

PAPER) is commonly known as dotted paper. It is a special modified
epoxy resin in the shape of diamond coating on electrical
insulation paper insulation material. It is widely used in
interlayer insulation and turn insulation of oil-immersed power
transformer. When used, the coating layer begins to melt at a
certain temperature during the coil drying process, resulting in
adhesion. As the temperature rises, it begins to cure again, so
that the adjacent layers of the winding are reliably bonded into a
fixed unit. The bonding strength of the epoxy resin is sufficient
to prevent the displacement of each layer of the winding during
short circuit, thus ensuring the long-term mechanical and
electrical properties of the insulation
structure.. INTRODUCE:Diamond Dotted Paper is made of Kraft
coated with heat curable epoxy resin, the epoxy adhesive is applied
to both sides of the paper in a diamond pattern consisting of
9.5mm×9.5mm diamonds with 15.9mm center spacing.Usage: DDP is
primarily used as layer and winding insulation in the LV and HV
coils of transformers. After curing, the partial resin coating
bonds the electric conductors with the insulation, which brings
about the mechanical consolidation of the coils. In this way the
radial and axial forces that arise in the event of
short circuit can be safely controlled.Usage:Diamond pattern
paper made of Kraft paper coated with heat curable epoxy resin.The
epoxy adhesive is applied to both sidesof the paper in a diamond
pattern consisting of 9.5mm x9.5mm diamonds with 15.9mm center
spacing.,the Diamond dotted Paper is to be used in oil-immersed
transformers for the insulation between of coils. On the insulation
layer, there is a layer dotted epoxy resin that will be changed
with high temperature change that is to be called as felt. It is a
kind of material with inertia, dry and no conglutination at normal
temperature (below 30ºC).The Diamond Dotted Paper (DDP) will make
the electric condctor forever felt up as a hard unit under the high
temperature by its internal latency substance When the temperature
is rising up to 90ºC, The Diamond Pattern Paper (DDP)begins one-off
thaw and then one-off solidification. DATA
