Fastening Fixture for Optical Cables

Fastening Fixture for Optical Cables (also known as optical cable clamps or cable hanging hardware) is a specialized overhead line accessory designed for secure, reliable installation of fiber optic cables — including ADSS and OPGW — on transmission towers and utility poles. Engineered to match the exact dimensions of tower main members and pole diameters, these fixtures provide high mechanical strength, easy installation, and long-term stability under wind, ice, and vibration loads.

Joint Box for Optical Cables | Fiber Optic Splice Closure for ADSS & OPGW

Joint Box for Optical Cables (also known as Fiber Optic Splice Closure or Optical Cable Joint Enclosure) is a robust, high-reliability enclosure designed for direct splicing and multi-branch joints of aerial fiber optic cables, including ADSS and OPGW. Engineered for overhead transmission and distribution lines, it delivers superior air-tightness, excellent oxidative resistance, and long-term environmental protection, ensuring uninterrupted optical signal transmission in harsh outdoor conditions.

Pre-Twisted Suspension Set for ADSS Optical Cables | Preformed Armor Grip Suspension

Pre-Twisted Suspension Set for ADSS Optical Cables (also known as Preformed Suspension Clamp or Armor Grip Suspension for ADSS) is a specialized overhead line fitting designed to securely suspend All-Dielectric Self-Supporting (ADSS) fiber optic cables on transmission towers and poles. Utilizing advanced pre-twisted (helical) armor rod technology, this suspension set distributes mechanical loads evenly, minimizes cable stress, and provides excellent vibration damping while maintaining full optical performance.

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.

Prestranded Suspension Clamp For OPGW Optical Cable | Preformed Helical Armor Grip Suspension

Prestranded Suspension Clamp For OPGW Optical Cable (also known as Preformed Suspension Clamp for OPGW, Helical Armor Grip Suspension, or Pre-Twisted Suspension Clamp) is a high-performance prestranded helical fitting designed for suspending Optical Fiber Composite Overhead Ground Wire (OPGW) cables on transmission towers, particularly at tensile or angle towers. This specialized clamp provides reliable protection and auxiliary damping while eliminating harmful stress concentrations, ensuring the cable maintains its full mechanical and optical performance under dynamic loads.

Prestranding Tension Clamp for ADSS Cable

Pre-Twisted Tension Set for ADSS Cables (also known as Preformed Tension Clamp, Helical Dead-End Clamp, or Prestranding Tension Clamp) is a high-performance overhead line fitting specifically engineered for terminating and tensioning All-Dielectric Self-Supporting (ADSS) fiber optic cables on transmission towers and utility poles. Utilizing advanced helical pre-twisted armor rod technology, this tension set securely grips the cable, distributes mechanical loads evenly, and provides effective vibration damping while eliminating harmful stress concentrations that could damage optical fibers.
