The DDP Epoxy Lingge Dispensing Insulating Paper

Product Description:

DDP Epoxy Diamond Grid Adhesive Insulation Paper

Epoxy diamond-grid insulation paper, made from high-quality electrician-specific power cable paper and coated with

modified epoxy resin in a diamond pattern on both sides, is widely used for interlayer and interturn insulation in oil-immersed

transformers and mutual inductors. It has gained industry-wide recognition.

Features

This product is a common interlayer insulation paper for transformers and mutual inductors. It has good oil absorption,

does not pollute oil, and exhibits excellent electromechanical properties in oil. The epoxy resin coating ensures strong

adhesion with coils and components, preventing displacement and loosening during operation for enhanced safety

and reliability.
