Prestranded Suspension Clamp for OPGW | Preformed Helical Armor Grip Suspension

Prestranded Suspension Clamp for OPGW (also known as Preformed Suspension Clamp, Helical Armor Grip Suspension, or Pre-Twisted Suspension Clamp) is a precision-engineered overhead line fitting designed to securely suspend Optical Fiber Composite Overhead Ground Wire (OPGW) cables on transmission towers. This prestranded helical clamp system effectively reduces static and dynamic stresses at the suspension point, enhances vibration resistance, and ensures the cable bending radius remains within safe limits, preventing harmful stress concentrations and additional optical fiber loss.

Key Features and Advantages

Stress-Free Cable Protection: Pre-twisted helical armor rods wrap directly around the OPGW cable, distributing mechanical loads evenly and eliminating point-loading that could damage the optical fibers.
Superior Vibration Damping: Effectively suppresses wind-induced aeolian vibration and dynamic stresses, significantly extending cable service life.
Easy Installation: Preformed design allows quick, tool-free hand application in the field, reducing labor time and installation costs.
Excellent Mechanical Performance: High grip strength combined with robust aluminum alloy components and rubber fixtures ensures reliable long-term performance under extreme weather conditions.
Corrosion Resistance: Aluminum alloy pre-twisted wires and galvanized hardware provide outstanding durability in harsh outdoor environments.
Quality Certified: Manufactured to ISO9001:2008 and ROHS standards for consistent quality and environmental compliance.

The clamp assembly consists of outer pre-twisted wires, inner guard strips, rubber fixtures, aluminum splints, U-shaped clips, and associated hardware (U-screw, ZH ring, bolts, nuts, etc.), supplied as a complete matched set.
