1. Energy Efficiency

Constructed from non-magnetic high-strength aluminum alloy, eliminating electrical hysteresis loss.

Certified as an energy-saving product compliant with ISO 50001 standards.

2. Installation Convenience

Bolt-based installation system enables quick, tool-free setup.

Reusable design reduces maintenance costs and environmental impact.

3. Stable Performance

Corrosion-resistant, wear-resistant, oxidation-proof, and UV-resistant properties ensure long-term reliability.

Operates consistently across -40°C to +85°C temperature ranges.

4. Reliable Grip Strength

Clamp grip force ≥ 95% of the conductor’s calculated breaking force (CBF).

Securely anchors conductors under extreme weather conditions

1. Power Line Anchoring

Application: Suitable for 20kV and below overhead power lines.

Function: Secures aluminum stranded conductors or aluminum-conductor steel-reinforced (ACSR) cables on tension poles.

Purpose: Anchors and tensions overhead conductors to ensure line stability and safety, meeting IEC 61284 mechanical load requirements.

2. Insulation Protection System

Integrated Design: Works with weather-resistant insulation covers (sold separately).

Safety Benefits:

Prevents current leakage and electrical shock hazards.
