Product Overview

The Suspension Clamp is a specialized tool used in power and communication lines to suspend and support wires, ensuring they remain securely fixed to power towers, poles, or other support structures. It is particularly effective for ADSS (All-Dielectric Self-Supporting) cables, OPGW (Optical Ground Wire) cables, and various types of wires. The clamp’s design incorporates pre-stranded inner and outer layers, which distribute stress evenly and prevent concentrated pressure points that could damage the optical cable. This feature is crucial for maintaining the integrity of high-voltage and high-capacity power lines.

Key Features and Functions

The Suspension Clamp is engineered to address multiple challenges in power and communication line systems. Its primary functions include:

• Wire Suspension: The clamp securely fixes wires to support structures, preventing displacement due to wind, temperature fluctuations, or mechanical stress.
• Stress Distribution: By combining inner and outer pre-stranded wires, the clamp minimizes bending and concentrated stress, reducing the risk of cable failure.
• Vibration Reduction: The design incorporates elements that absorb vibrations caused by wind or seismic activity, enhancing the longevity of the cable.
• Corrosion Resistance: Constructed from materials like galvanized steel, aluminum alloy, or stainless steel, the clamp withstands harsh weather conditions, including high humidity and salt spray.
• Easy Installation: The clamp’s simple structure allows for quick and efficient installation without requiring complex tools or expertise.
