The I-shaped pull strip is a composite profile with a distinctive I-shaped cross-section.
G10 / G11 / FR4 / 3240 Epoxy Boards
G10 and G11 epoxy resins are made by impregnating electronic-grade glass cloth with heat-resistant epoxy resin, followed by thermal pressing.

G10 and G11 epoxy resins are made by impregnating electronic-grade glass cloth with heat-resistant epoxy resin, followed by thermal pressing.
A composite material made from epoxy resin and glass fiber (or alkali-free cloth), characterized by high mechanical strength and excellent dielectric properties, is widely used in components such as electrical equipment, transformers, and surge arresters.
The Yantail pad blocks have a wide range of applications, commonly found in electrical equipment, distribution cabinets, switchgear, and more—used for insulating and supporting components as well as ensuring secure positioning. In electronic circuit board manufacturing, they can also be employed to insulate and precisely position electronic components, enhancing the stability and safety of electronic products.
Insulation pads, often referred to in the industry as resin pads, high creepage distance pads, or pads specifically designed for dry-type transformers, are commonly abbreviated as DMC, reflecting their typical material composition.
Aluminum alloy castings refer to aluminum alloy components produced by gravity casting, using a mold to achieve their final shape.
Electrical equipment: motor end covers, insulator flanges, distribution box bodies, and more.
Aluminum alloys have low density; compared to spacer bars made of conventional steel, they are lighter in weight and easier to install and maintain. This effectively reduces the load-bearing pressure on supporting structures such as towers and pylons, decreases the amount of materials required for towers, and lowers the construction costs of transmission lines.
In the field of electromechanical engineering, it is often used in scenarios such as distribution cabinets and the frame assembly of large-scale electromechanical equipment, serving to connect, secure, and enhance the overall structural rigidity—thereby ensuring the stable operation of electromechanical devices.
