Preformed Suspension Clamps (SCL) - China Factory Suppliers for Ultra-High-Voltage Line Protection

Purpose

,

Manufactured in China by reputable suppliers and factories, preformed suspension clamps employ a combination of preformed suspension sets and guard wires. They are meticulously designed to reduce both static and dynamic stresses at support points, ensuring that conductors and ground wires remain protected from wind-induced effects. Additionally, these clamps provide a robust shield for guard wires against impact and electrical abrasion at the supports. As a premier integrated suspension assembly, preformed suspension clamps safeguard conductors from bending stress, compressive stress, and wear, making them an essential choice for high-performance transmission projects.

    Frequently Asked Questions (FAQ)

    What standard do these preformed suspension clamps comply with?
    These clamps correspond to the industry standard model GB/T 1179-83 (specifically the LGJ/LGJF Series) designed for steel core aluminum conductors.
    How do I interpret the model numbering system?
    In the model code, "C" stands for Suspension clamp, "L" stands for Preformed spiral type, and the following numbers represent the applicable conductor model.
    What is the purpose of the color code in the specifications?
    The color code (e.g., Red, Yellow, Blue, Pink) is used to easily identify the specific clamp size and correspond to the matching conductor diameter range during installation.
    What is the vertical breaking strength of these suspension clamps?
    Depending on the model, the vertical breaking strength ranges from 66 kN for smaller conductor models (such as CL-35 to CL-185) up to 111 kN for heavy-duty models (such as CL-400 to CL-800).
    Can I order custom specifications not listed in the table?
    Yes. The specification table lists only partial products. For customized specifications or other conductor configurations, please contact our support team directly.
