All-dielectric Self-support 6 Core Fiber Optic Cable ADSS Fiber Optic Cable

ADSS optical cable adopts loose layer stranded structure. 250 µ M optical fiber is sleeved into a loose tube made of high modulus material, which is filled with waterproof compound. The loose tube (and filling rope) is twisted around the non-metallic central reinforcing core (FRP) to form a compact cable core, and the gap of the cable core is filled with water blocking ointment. The cable core is extruded with polyethylene (PE) inner sheath, then twisted with aramid for reinforcement, and finally extruded with polyethylene (PE) outer sheath or at outer sheath.

Structure characters

•Loose tube with non-metallic strengthen member
•High flexible amaid yarn
•Can work at electric field<=25KV/m in a long period

•Accurate process control ensuring good mechanical and temperature performances
• All-dry design improving efficiency of construction and splicing
• Small size, light weight and soft, applicable for self-supporting aerial installation
• Aramid yarns providing good tensile performance

Properties

1. Up to 144 optic fibers.
2. Light weight, less additional load to tower. The maximum span can reach 1500m.
3. Strong anti-pull performance, more than 90KN.
4. Non metallic structure provides good insulation, excellent lightning resistant.
5. Equal distribution of aramid yarns with good production process, excellent stress/strain performance.
6. Excellent bullet resistant performance.
7. Excellent tracking resistant performance.
8. Installation wuthout power off and the normal transmission of cable won't be influenced by power line fault.

Applicable Fields

1. Long distance telecom, LAN in high voltage area or access to telecom network.
2. For power transmission system, much thunder areas and high electro-magnetic inerference.
