The 3240 epoxy glass cloth laminate is a type of organic polymer laminate
produced by impregnating electrical-grade glass cloth with epoxy resin, followed
by drying and hot-pressing.

FR-4 epoxy glass cloth laminate is made of epoxy resin and glass cloth.

SMC molded (high-pressure) insulation board is a sheet-like product manufactured
through high-temperature compression molding using a glass fiber-reinforced
sheet molding compound (SMC) composed of unsaturated polyester resin (UP),
specialized glass fiber (GF), inorganic fillers, and various additives

PVC plastic sheet is a polymer material made primarily from polyvinyl chloride (PVC)
resin, with the addition of auxiliary agents such as stabilizers and plasticizers.

DMD is a exible composite material, consisting of three layers of insulating paper made
of polyester lm coated with adhesive on both sides and bonded with polyester ber
nonwoven fabric.

6640NMN Grade F is a three-layer flexible composite material. The outer two layers
are Arclin (formerly DuPont) NOMEX® paper, and the inner layer is a polyester film.

Composite fish (yellow shell) paper, commonly known as (6520, 6521) polyester film
insulating paper flexible composite material, is a double-layer insulating material formed
by laminating fish (yellow shell) paper with polyester film (PET film). This combination
effectively integrates the mechanical strength of fish (yellow shell) paper with the
excellent dielectric properties of polyester film

Polyester film capacitor paper flexible composite foil is made of electrical
polyester film and two layers of capacitor paper (abbreviated as PMP).

Semiconductor crepe paper is a special electrical insulation material that
combines conductivity (semiconductor grade) and physical flexibility (crepe paper
characteristics).

High-voltage crepe paper serves as core insulation for transformers and
instrument transformers. Treated via special creping, this electrical insulation
paper features high elongation and flexibility, enabling tight wrapping on
irregular and curved conductor surfaces.

2210 Oil-based lacquered silk (yellow wax silk) is an electrical insulating soft
material made by uniformly impregnating refined mulberry silk with oil-based
insulating varnish, and then drying and rolling it up

DMD epoxy prepreg material, grade F, is a flexible composite material formed by
impregnating grade F epoxy resin with a flexible nonwoven polyester film and
polyester fiber composite material and then semi-curing it

F4 glass cloth, also known as polytetrafluoroethylene glass cloth, is a highperformance composite material. It is made by impregnating alkali-free glass
cloth with a polytetrafluoroethylene (PTFE) dispersion, followed by drying,
baking, and sintering processes

SHS epoxy prepreg material H-class is a semi-cured (Phase B) insulating composite
material specifically designed for H-class (180°C) dry-type transformers and motors.

Fiberglass mesh is a high-performance insulating reinforcement material
specifically designed for dry-type transformers. It can be viewed as a composite of
fiberglass woven fabric and epoxy resin
