Wedge Insulation Strain Clamp
Details
The NXL Wedge Insulation Strain Clamp features a wedge-type insulated self-locking design and serves as a core load-bearing hardware component for overhead distribution lines. Its primary function is to secure and tension conductors on insulators at turnouts or terminal tension poles, transferring conductor tension while ensuring a reliable electrical connection. It combines the functions of securing, tensioning, and providing insulation protection.
Suitable Conductors: Compatible with 25mm²–400mm² overhead insulated aluminum conductors, bare aluminum conductors, and aluminum stranded wire (LJ). The full series ranges from NXL-1 to NXL-4, accommodating various conductor cross-sections and corresponding outer diameter requirements.

Product Introduction

Materials of Wedge Insulation Strain Clamp

  • Materials: The main body is made of non-magnetic, high-strength, oxidation-resistant aluminum alloy, which eliminates hysteresis loss, saves energy, and reduces consumption, meeting the requirements for aluminum-to-aluminum contact in aluminum conductors; the accompanying insulating cover is made of weather-resistant insulating material, and the fasteners are made of hot-dip galvanized high-strength steel for rust and corrosion resistance; all metal components undergo anti-corrosion treatment to extend outdoor service life.

Installation Steps

 
Direct from the manufacturer, great value for money.
 

Thread the wire through the clamp body and insert the wedge core, ensuring the wedge core fits snugly against the wire and is flush at both ends;
Use a tensioning tool to tighten the wire to the appropriate tension, then gently tap the end of the wedge core to pre-tighten it, taking care not to damage the wire insulation;
Remove the tensioning tool and adjust the nut to meet project specifications;
Slide on the insulating sleeve to complete the insulation protection.
Precautions: The installation direction of the wedge core must align with the direction of force on the wire to prevent the wire from slipping due to incorrect installation; sufficient length must be left at the wire end, and the exposed portion must be treated to prevent strand separation; the insulating cover must be installed properly to ensure a sealed protection. No complex modifications are required, allowing for rapid deployment.

FAQ

 

Q:Are there third-party test reports for the products?

A:All standardized products come with type test reports and factory inspection reports. We can provide test certificates issued by national-level power testing institutions (such as the Electric Power Research Institute or the Quality Inspection Institute).

Q: What is the primary application of the NXL Wedge Insulation Strain Clamp?

A: It is primarily used on tension towers and angle towers in overhead transmission lines to anchor conductors or lightning arresters to tension insulator strings, bearing the full tension of the conductor.

Q: What does the NXL Wedge Insulation Strain Clamp model designation represent?

A: N stands for tension, X stands for wedge-type/wedge structure, and L stands for aluminum alloy material; it is a commonly used wedge-type aluminum alloy tension clamp.

Q: What types of conductors are NXL Wedge Insulation Strain Clamps suitable for?

A: They are suitable for steel-core aluminum stranded wire, aluminum stranded wire, aluminum alloy stranded wire, and certain types of steel stranded wire. Different models correspond to different conductor cross-sections.
