PS hanging clamps are a type of electrical fitting mainly used for suspending and securing conductors or optical cables in overhead lines. Below is a detailed description:
PS hanging clamps usually consist of a body and a pressure plate made of forged iron. The closed pin is made of stainless steel, while other parts may be copper. The clamp body is typically in the shape of a U-bolt. Some PS hanging clamps designed for suspending optical cables may additionally include internal and external threaded fittings, rubber clamping blocks, U-shaped rings, aluminum housings, and triangular connecting plates.
Certain components of PS hanging clamps, such as the hanging plate, are made of hot-dip galvanized steel to ensure corrosion resistance and wear resistance. In addition, some PS hanging clamps have bodies made of glass fiber-reinforced thermoplastic materials, which provide UV radiation resistance.
PS hanging clamps have excellent mechanical properties, reliably fixing conductors or optical cables to ensure stability under various operating conditions. Some models feature tool-free installation thanks to wing nuts. Their structure usually allows for angular deviations of the line, and some versions can be installed on straight sections or at angles up to 30°.
PS hanging clamps are mainly used on straight supports to fasten conductors to insulator strings. They can also be used for suspending lightning conductors on straight supports. These clamps are widely applied in specialized scenarios of power transmission lines with long spans and significant height differences, such as the suspension and fixation of ADSS optical cables and OPGW optical cables.
