1. Material Properties

Constructed from high-strength aluminum-magnesium alloy, the clamp features a low density, making it lightweight and easy to carry and operate. Despite its lightness, it offers high strength, capable of withstanding significant tensile forces, ensuring reliable performance in cable tensioning or fixing tasks.

2. Insulation Performance

Equipped with excellent insulating properties, it can withstand a specified voltage range, effectively preventing current leakage and electric shock. This ensures construction safety in live-line working scenarios, such as maintenance or installation on energized power lines, where electrical isolation is critical.

3. Conductor Compatibility

Specifically designed for insulated conductors with a cross-sectional area of 25–70 mm², the clamp’s opening size and other design parameters are matched to this conductor specification. This ensures a secure grip on the conductor, minimizing the risk of slippage during operations like tightening or pulling.

4. Conductor Protection

The clamp’s jaws undergo special treatments, such as knurling or embedding soft wear-resistant materials. This design provides reliable clamping force while avoiding damage to the conductor’s insulation layer, preserving the integrity of the cable and ensuring long-term electrical performance.

1. Safe and Reliable

With excellent insulation performance and a secure clamping structure, it ensures the safety of construction personnel while preventing conductor slippage during operations. This enhances the overall safety and stability of construction, making it ideal for live-line work or high-precision cable fixing tasks where electrical isolation and mechanical reliability are critical.

2. Lightweight and Efficient

Its lightweight design allows single-person operation, and the simple, quick clamping mechanism improves construction efficiency while reducing labor intensity. Technicians can easily carry and deploy the clamp in various scenarios, such as overhead line maintenance or tight-space installations, saving time and effort compared to heavier metal clamps.

3. High Durability

Made from corrosion-resistant and wear-resistant aluminum-magnesium alloy, combined with robust design and manufacturing processes, the clamp features a sturdy structure that withstands harsh outdoor environments . Its long service life reduces replacement costs and ensures reliable performance in long-term power engineering projects or frequent-use scenarios.

1. Sag Adjustment

In the construction and maintenance of overhead power lines, it is used to adjust the sag of insulated conductors. By clamping the conductor securely and coordinating with related tools, the conductor is adjusted to an appropriate arc, ensuring the safe operation of the line. This is critical for maintaining proper clearance between conductors and ground/objects, as well as optimizing power transmission efficiency.

2. Conductor Fixing and Tensioning

During conductor erection, deployment, or tightening operations, the clamp securely holds and fixes insulated conductors, providing stable clamping force to facilitate tasks such as line tensioning and stringing. This ensures the conductor tension meets design requirements, preventing issues like over-stretching or excessive sag that could compromise line stability.

3. Auxiliary Jointing Operations

In insulated conductor jointing tasks , the clamp fixes both ends of the conductors to be joined, keeping the joint area tension-free. This helps improve joint quality by ensuring precise alignment and reducing mechanical stress during the connection process, which is essential for maintaining the electrical and mechanical integrity of the conductor joints.
