DIAMOND
DOTTED PRESSPAPER (D.D.P.) |
|
|
|
Composed
of electrical insulation paper with diamond-shape epoxy resin
dotted in both sides. The epoxy resin used in D.D.P. contains
a kind of incubative hardener material. It is a dry and crisp
material at normal temperature (below 35° C or 95° F).This
flexible material has good dielectric properties and
good mechanical properties after heat-solidification. It is
suitable as insulation material for coils and between layers
of coil in the oiled–liquid power and distribution
transformers. |
