Electrical-grade diamond-pattern adhesive dotting paper
A diamond-patterned coating of specially modified epoxy resin is applied to high-performance insulating paper. This serves as turn and interlayer insulation for windings in oil-immersed power transformers. After winding and baking, it effectively prevents layer displacement within the windings, ensuring stable electrical and mechanical performance of the insulation structure.
Dielectric Insulating Film with Diamond-Grip Coating for Electricians
The dielectric film with diamond-patterned adhesive coating for electrical applications is an insulation material made by baking a modified special epoxy resin onto polyester film used in electrical equipment. The resin coating on the polyester film is applied in a dotted pattern rather than as a continuous layer, leaving uncoated channels that facilitate the flow of insulating gas. This design minimizes corona and partial discharge damage. It can be used as interlayer insulation in gas or oil-based insulation systems. Primarily used for interlayer and turn-to-turn insulation in sulfur hexafluoride (SF6) instrument transformers and specialized transformers.
Composite Pallet
Composite panel: Made by laminating electrical-grade polyester film coated with a specialized heat-resistant adhesive to polyester fiber nonwoven fabric, followed by surface treatment with a special resin. Primarily used as an insulating cylinder between high-voltage and low-voltage windings in dry-type transformers.
Soft composite materials for electricians

Composite materials
Soft composite materials for electrical use, primarily B and F class (DMD, NMN, NHN), offer excellent mechanical and electrical properties. They are widely used for slot-to-slot and phase-to-phase insulation in high- and low-voltage motors, as well as interlayer and end-turn insulation in transformers.
Polyester Film Polyaramid Fiber Paper Soft Composite Material (NMN)
NMN is a three-layer flexible composite material made by bonding two sides of calendered NOMEX paper to a central polyester film using H-class high-temperature adhesive. The product offers excellent mechanical and electrical properties. It is suitable for slot, phase-to-phase, and turn-to-turn insulation in F/H class motors and electrical equipment.
Polyimide Film/Polyaramid Fiber Paper Soft Composite (NHN)
NHN is a three-layer flexible composite material consisting of a polyimide film core bonded on both sides with calendered polyaramid fibers using H-class high-temperature adhesive. The product offers excellent heat resistance, superior mechanical properties, and outstanding electrical performance. It is suitable for slot, phase-to-phase, and turn-to-turn insulation in H-class and 200-class motors and electrical equipment.
Crepe paper and crepe paper tubes

Electrical Insulating Crinkled Paper
Crepe paper is primarily made from Sanmu high-quality electrical-grade crepe paper. It is used for insulating windings in oil-immersed transformers, reactors, and instrument transformers. The full width is 550mm, 1100mm. Recommended thicknesses include 0.35mm, 0.46mm, 0.55mm( (heat-resistant), 0.65mm, and 0.8mm. It offers excellent tensile strength, elongation, conductivity, and low dielectric loss.
Insulated Corrugated Paper Tube
The corrugated paper tube is manufactured from imported Sanmu crepe paper. It is primarily used as a flexible insulating sleeve for the high-voltage and low-voltage taps and studs inside oil-immersed transformer cores. The tube offers reliable flexibility and can be bent in any direction without cracking.
