CE Certification Preformed Tension Clamps (SNL) Manufacturer, Suppliers

Utility Model Patent No.: ZL 2012 0507136.3

Preformed tension clamps have various types, including preformed conductor tension clamps, preformed ground wire tension clamps, and preformed tension clamps for pull lines. They can replace NY-type, NLL-type, and N-type clamps (commonly used for fixing conductors on poles/towers in China), as well as F-type and NXG-type clamps applied to OPGW.

The structure of preformed tension clamps is simple: they form a hollow tube via double-helix twisting, with preformed twist loops at the end. When spirally wound around conductors or ground wires, the clamps generate a gripping force, while the twist loops fasten to insulators, poles, towers, or ground anchors. Their unique principle and structure give them distinctive performance and features.

Frequently Asked Questions

What standards do these conductors comply with?

Our ACSR and AAC conductors are manufactured in strict accordance with the GB/T1179-1983 and LGJ/LGJF standards, ensuring high quality and reliability for power transmission.

How do I choose between ACSR and AAC conductors?

ACSR (Aluminum Conductor Steel Reinforced) is typically used for long spans and high-tension requirements due to its steel core, while AAC (All Aluminum Conductor) is preferred for shorter spans and urban areas where high conductivity and corrosion resistance are prioritized.

What does the "Color Code" represent in the AAC table?

The color code is used for quick identification of the conductor specifications and sizes during installation and maintenance in the field.

Are custom lengths available for specific projects?

While the tables list standard catalog lengths, we provide various specifications to match different engineering requirements. Please refer to the O.D and Section values to find the best fit.

What is the significance of the "Pieces" column in the ACSR table?

The "Pieces" column indicates the standard packaging or segment count typically associated with the specific catalogue number for logistical planning.

How is the Outer Diameter (O.D) measured?

The O.D (Outer Diameter) is measured in millimeters (mm) and represents the total thickness of the finished conductor, which is critical for choosing the correct fittings and insulators.
