Preformed Tension Clamps for China: Reliable Suppliers and Factory Solutions for Conductors and Ground Wires

Utility Model Patent No.: ZL 2012 0507136.3

,

Preformed tension clamps, available from top suppliers in China, encompass a variety of types, including preformed conductor tension clamps, ground wire tension clamps, and clamps for pull lines. These innovative clamps serve as replacements for NY-type, NLL-type, and N-type clamps commonly utilized for securing conductors on poles and towers, as well as F-type and NXG-type clamps designed for Optical Ground Wire (OPGW) applications.

,

The design of preformed tension clamps is straightforward yet effective: they are crafted into a hollow tube through a double-helix twisting process, featuring preformed twist loops at the ends. When securely wound around conductors or ground wires, these clamps exert a gripping force that enhances stability, while the twist loops anchor firmly to insulators, poles, towers, or ground anchors. The unique design and operational principles of these clamps result in exceptional performance and reliability, making them a superior choice for various installations.

,

As a leading factory in China, we pride ourselves on providing high-quality preformed tension clamps that meet the diverse needs of our customers.

    Frequently Asked Questions (FAQ)
    Q1: What standard do these conductors comply with?
    These conductors are manufactured in strict compliance with the GB/T1179-83 standard, specifically covering LGJ and LGJF types, ensuring high-quality performance and safety for overhead power lines.
    Q2: What does the "O.D (mm)" represent in the specification table?
    "O.D" stands for Outer Diameter, measured in millimeters. It represents the total external thickness of the conductor, which is critical for selecting compatible hardware, clamps, and installation tools.
    Q3: Can the length of the conductors be customized?
    Yes. While the table lists standard lengths for typical applications, custom lengths can be manufactured and supplied to meet specific project layouts and transmission line requirements.
    Q4: What are the primary applications of LGJ/LGJF conductors?
    These steel-cored aluminum stranded conductors (ACSR) are primarily designed for overhead electrical power transmission and distribution lines, offering an optimal balance of tensile strength and electrical conductivity.
    Q5: What does the "Pieces" column indicate?
    The "Pieces" column specifies the standard packaging count or segment structure of the conductor batch per delivery unit, helping with project planning and logistics management.
