1.2 This product is a composite material of polyester film compounded by F grade adhesive hot rail. It has the characteristics of no creepage, small partial discharge, high pressure resistance, high mechanical strength, no deformation, no layering, and anti-aging.
1.3 This product is suitable for the insulation cylinder of dry-type transformers and is an ideal product to replace glass cloth insulation cylinder. It is placed between dry-type transformers and low-voltage coils to increase insulation strength, effectively reduce the spacing between high and low-voltage coils, reduce the volume of transformer high-voltage coils, and reduce the material cost of transformer coils. This product is also suitable for insulation between motor slots.
