Product Details
Description
Outdoor optical cables for communication purpose with metal-reinforced components, filling mode by loose tube layer stranded, aluminum-polythene sheaths, polythene sheaths of corrugated steel tapes, and polythene outside expansion layer of armoured installation by double round steel wires.
Structure Characteristics
- Fiber loose tube, metal-reinforced components
- Filling ointment in the core of the Cable
- Plastic coated aluminum bands be felt to PE inner sheath
- Armoured steel wire plus outer sheath
Layingapply to directly bury, shallow-water and grade laying
Technical Features
- Inimitable PBTP tube sheathing techniques causes nice flexibility and bending resistance of the tube
- Inimitable excessive length control and SZ twist cable forming method makes the excellent mechanical and environmental performance
- Filling the water blocking ointment procedure by procedure, which can double block water in the complete section
- The armoured layer is made by rolling double deck steel wire, which ensures the mechanical pressure and bullets resistance of the Optical Cable and meet the requirement of underwater laying
