Product Description

Product features: With power cable paper as the base material and composite epoxy resin as the adhesive, the double-sided diamond-shaped glue dots are printed on the base material by the equipment, and then baked, dried and rolled to form a double-sided diamond-shaped glued insulation paper.

Product thickness: 0.08mm / 0.13mm / 0.18mm / 0.25mm

Product width: 625mm / 960mm / 1020mm / 1100mm (special specifications can be produced according to customer requirements)

Glue dot size: 9.4mm X 9.4 mm Glue dot interval: 6.5mm

Product introduction: AMA is a new type of electrical insulation material made of polyester film and two layers of cable paper, and then the special modified epoxy resin is evenly coated on AMA in a diamond shape. It is used for oil-immersed transformers to replace the original insulation material.
