Product Description

Detail of Oil transformer insulation paper struct  :

Oil transformer insulation paper struct   is  made up of strips of transformer board glued to Diamond pattern resin coated paper (DDP). ;widely used in oil-immersed transformer,avoiding the traditional use of corrugated board easy to deformation,displacement and so esay to produce vulnerability to and coil with firm,and has better mechanical,electrical performance.

100% sulphate wood pulp

Natural-Color

High Purity and mechanical strength

Low shrinkage and compressibility

Good compatibility with liquid dielectrics

Insulation class A (105°C)
