ASU Mini All-Dielectric Self-Supporting Fiber Cable | Factory Supply

ASU Mini All-Dielectric Self-Supporting Optical Fiber Cable (2-24 Cores)

Ultra-Lightweight & Lightning-Proof Aerial Connectivity

The ASU Mini All-Dielectric Self-Supporting (ADSS) Cable is a compact, high-efficiency solution designed specifically for overhead power systems and high-interference environments. By utilizing a completely non-metallic construction with high-strength Fiber Reinforced Plastics (FRP), this cable eliminates the risk of electrical induction and lightning damage. Its “mini” profile makes it an ideal choice for streamlined, cost-effective aerial network deployments where safety and durability are paramount.

Key Product Features

• All-Dielectric Safety: Constructed entirely without metallic components, making it immune to electromagnetic interference (EMI) and safe for installation near high-voltage power lines.
• Compact Self-Supporting Design: Features two integrated non-metallic FRP strength members twisted with the central tube to form a compact cable core, allowing for self-supporting aerial spans without a separate messenger wire.
• Advanced Moisture Protection: The central loose tube is filled with water-resistant jelly and wrapped with water-blocking yarn to ensure the core remains watertight and signal-stable.
• High-Modulus Protection: Fibers are housed in a high-modulus plastic tube designed to protect the $250\mu m$ cores from mechanical stress and environmental factors.
• Weather-Hardened PE Sheath: Encased in a rugged Polyethylene (PE) jacket that provides excellent UV protection and durability in extreme climates.
