  • Product Description
  • Product Introduction

    Yantail pads are a type of specially shaped insulating material product, named for their resemblance to a swallow's tail. 
    Material-wise, it is typically made from high-quality insulating plastics, rubber, or composite materials, offering excellent electrical insulation properties. This effectively prevents the flow of electric current, helping to avoid electrical faults such as leakage and short circuits, thereby ensuring safe electricity usage. 
    In terms of structural design, the dovetail shape allows it to fit snugly into a specific dovetail groove during installation, creating a stable connection that is resistant to loosening or shifting, thereby enhancing the overall reliability of the structure. 
    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 serve to insulate and precisely position electronic components, enhancing the stability and safety of electronic products.
