Preformed Tension Clamps in China - Quality Suppliers and Factory for Conductors and Ground Wires

Utility Model Patent No.: ZL 2012 0507136.3

,

Our preformed tension clamps, designed for various applications, include preformed conductor tension clamps, ground wire tension clamps, and clamps for pull lines. These clamps effectively replace popular designs such as NY-type, NLL-type, and N-type clamps widely used for securing conductors on poles and towers in China. Additionally, they can substitute F-type and NXG-type clamps used in OPGW installations.

,

The innovative structure of our preformed tension clamps features a double-helix twisted hollow tube with preformed twist loops at the ends. When spirally applied around conductors or ground wires, these clamps create a robust gripping force. The twist loops secure the clamps to insulators, poles, towers, or ground anchors. With their unique design and functionality, our preformed tension clamps stand out in performance and reliability. As a leading factory among China suppliers, we ensure high-quality products that meet industry standards.

    Frequently Asked Questions

    Q What manufacturing standard do these conductors follow?

    These LGJ and LGJF conductors are manufactured in strict compliance with the GB/T1179-83 standard, ensuring high reliability and performance for electrical power transmission.

    Q What does the "O.D (mm)" column represent in the specification table?

    "O.D (mm)" stands for Outer Diameter. It represents the total external diameter of the conductor in millimeters, which is crucial for determining installation clearance and hardware compatibility.

    Q How does the section size vary across different catalogue numbers?

    The nominal section area varies depending on the catalogue number, ranging from smaller configurations like LNL-16/3 up to heavy-duty configurations like LNL-300/50 to suit different current carrying capacity requirements.

    Q What is the significance of the "Pieces" column?

    The "Pieces" column indicates the quantity or standard unit packaging count associated with each specific conductor model length in our standard inventory.

    Q Can these conductors be customized for specific project lengths?

    Yes, while our standard catalogue lists specific lengths (such as 444mm to 1442mm units), we can accommodate customized length and packaging specifications based on your project requirements.
