Waterblocking Glass Yarns is a kind specialized yarns with good water absorption capacity, mainly used for moisture control and reinforcement in coating protection of Cable, optical Cable, communication Cable or fiber optic Cable.
Composition
Polyester Terylene long fiberAdvantages:
Optimize cable structure, replace jelly for water blocking
Relative humidity inside the cable is kept below critical levels
Prolonged cable life due to slower or zero water tree growth
Life spans over than 30 years with the proper materials
No need for a metal (radial) water barrier.
Less environment impact
More reliable and cleaner cable production.
Lower investment in manufacturing equipment.
To avoid extrusion from finished cable/plastic mold on optical fiber bundle tube, and reduce defective rate
