     Preformed Tension Clamp for ADSS OPGW OPPC

     

    Product Description

    THE PREFORMED TENSION SET is widely used for the installation of bare conductors or overhead insulated conductors for transmission and distribution lines, the reliability and economic performance of the product is better than the bolt type and hydraulic type tension clamp that widely used in the current circuit.

    Innovative structure and precision design, so that the preformed tension set has a reliable performance and it is usually made of aluminum clad steel, galvanized steel wire and other materials.

  • A preformed tension clamp is used on the power lines to provide mechanical support and tensioning of conductors. It is designed for use in overhead power transmission and distribution systems. They secure and support the conductor in a tense position. The clamps are made of high-strength materials such as aluminum alloy or steel with specific contours and shapes to accommodate the conductor and provide a secure grip. The design allows for adjusting and controlling the tension applied to the conductor. The claps also help prevent excessive sagging and vibration or movement of the conductor due to external factors.

     

    The specific components and their arrangement vary between different manufacturers and designs of preformed tension clamps. The components work together to secure and support the conductor on the power lines. The design and components may also vary depending on the manufacturer and application. The following are the components of the preformed tension clamps.

     

    Gripping elements – These are the features that directly engage with the conductor to provide a secure grip. Gripping elements can be in the form of serrated jaws, wedges or other structures designed to hold the conductor firmly in place.
    Clamp body – The clamp body serves as the main structure that houses the gripping elements and provides support. It is made of durable and corrosion-resistant materials like aluminum alloy or steel.
    Fastening fittings – Preformed tension clamps work with bolts and nuts to secure the clamp body and provide tension adjustment.
    Tensioning device – The device allows for adjusting and controlling the tension applied to the conductor. It includes components like a threaded rod, turnbuckle and other tensioning elements to facilitate the desired tensioning of the conductor.
    Spacer plates – Spacer plates provide separation and insulation between the clamp body and the conductor. They prevent electrical contact or galvanic corrosion between the clamp and the conductor.
    Coatings – Protective coatings enhance durability and resistance to corrosion and prolong the lifespan of the clamp.

  • The types of preformed tension clamps vary in design, materials and specific applications. Choosing the preformed tension clamp depends on a number of factors like conductor size, tension requirements, environmental conditions and specific installation requirements. The different designs and specifications allow them to be applicable in various applications in the overhead power lines. the following are the common types of preformed tension clamps.

    • Dead-end clamps – Dead-end clamps are also used to secure the conductor at the termination points of power lines. they install where the conductor ends or where it is attached to insulators, poles or other supporting structures.
    • Suspension clamps – Suspension clamps support the weight of the overhead conductors in transmission and distribution lines. they install at the suspension points along the power line to maintain the desired tension and prevent excessive sagging.
    • Mid-span clamps – The clamps provide additional support and tension control at the intermediate points along long spans of power lines. they reduce excessive sagging and ensure the proper tension distribution along the conductor.
    • Strain clamps – The strain clamps provide tension and anchor the conductor. They also absorb the mechanical forces generated by the tension in the conductor and maintain its position.
    • Guy wire clamps – Guy wire clamps have a design that secures the guy wires used to support power line structures like poles or towers. They provide tension and stability to the guy wires thus ensuring proper alignment and support for the power line infrastructure.
    • Armor rod clamps – These are also known as vibration dampers used to reduce the vibration and oscillation of conductors caused by wind or other dynamic forces.
  • The specific application of preformed tension clamps varies depending on the type of power line, voltage level, conductor size, environmental conditions among other factors. Industry professionals can provide more precise guidance on the appropriate use of preformed tension clamps in specific applications. The following are the applications of the preformed tension clamps.

    • Guy wires – Tension clamps ensure proper tensioning of the guy wires, maintaining structural stability and preventing excessive movement or swaying.
    • Overhead transmission lines – Preformed tension clamps help to support and tension the conductors on the overhead transmission lines.
    • Railway electrification – Preformed tension clamps are used to secure and tension the overhead or contact wires. They provide the necessary support and tension to ensure continuous and reliable power supply to electric trains.
    • Substation installations – Preformed tension clamps work in substation installations to support and tension the conductors connecting different components of the electrical grid. They also maintain proper tension in the cables or busbars.
    • Communication lines – The clamps also work in installations such as fiber optic cables or telephone lines. they assist in securing and tensioning the communication cables and ensure reliable transmission of signals over long distances.
    • Distribution lines – The clamps deliver electricity to residential, commercial and industrial areas to secure and support conductors. This provides the necessary tension for efficient power distribution.
