G10 and G11 epoxy fiberglass laminate sheets are high-strength electrical insulation materials made from glass fiber cloth impregnated with epoxy resin and laminated under heat and pressure. They combine excellent electrical insulation, mechanical strength, dimensional stability and moisture resistance, making them widely used in electrical equipment, transformers, motors, switchgear, fixtures and structural insulation parts.

Chengrui supplies both G10 epoxy fiberglass laminate sheet and G11 epoxy fiberglass laminate sheet and FR4 insulation sheet in different thicknesses, colors, sheet sizes and machined parts according to customer requirements. Standard sheets can be supplied directly, and custom cutting, CNC machining, drilling, milling and shape processing are available for insulation components.

G10 epoxy fiberglass laminate sheet is a rigid laminated insulation sheet made from epoxy resin and fiberglass cloth. It is one of the most commonly used epoxy glass laminate materials for electrical insulation and mechanical support.
G11 epoxy fiberglass laminate sheet is a higher-temperature epoxy fiberglass laminate. It is also made from epoxy resin and fiberglass cloth, but compared with G10, G11 is designed for better thermal performance and improved stability under elevated temperature conditions.

Transformer insulation pressboard is a rigid cellulose board used for barriers, spacers, cylinders and other structural insulation parts in oil-filled transformers. It offers good mechanical strength, dielectric insulation and oil compatibility.

Why Pressboard Is Used in Transformer Insulation

In transformers, insulation is not only an electrical issue. It is also a structural and mechanical issue.

That is why pressboard transformer insulation is widely used. Compared with thinner insulation papers, pressboard provides:

higher mechanical strength

better dimensional stability

stronger support for internal parts

good dielectric insulation

good performance in oil-immersed transformer systems

Diamond dotted paper (DDP) is an electrical insulation presspaper partially coated with heat-curable epoxy resin dots arranged in a diamond pattern. During coil drying / oven heating, the resin dots soften and cure to bond adjacent layers, helping improve winding mechanical stability in transformer manufacturing.

DDP insulation paper is commonly used as interlayer insulation between coils in oil-immersed transformers, where controlled bonding is needed without sacrificing oil impregnation and drying efficiency.
Chengrui Insulation can provide DDP insulation paper in rolls with different thicknesses, widths, and slitting options according to production requirements. Our team can help confirm roll size, resin dot pattern requirements, packing method, sample availability, and bulk order delivery schedule.
