Glass yarn for optical cables
Product introduction
1. Protect the internal structure of the optical cable (the glass sheath completely covers the first sheath, effectively protecting the internal structure from damage)
2. Prevent squirrels from biting people (glass gauze can prevent or reduce squirrels from biting optical cables). Even if the outer skin is bitten through, the glass gauze prevents the rat from biting and provides additional protection.
3. Improve the strength of the cable (high-strength glass fiber material makes the cable anti-rat bite effect is excellent, improve the durability and life of the cable)
4. The surface is attached with a layer of soft PU adhesive film, good tensile performance, not easy to break, and the optical cable processing does not hurt the human body
At present, the model of glass fiber is 300D/600D/785D/1200D, which is divided into ordinary glass fiber and water-resistant glass fiber, which can be selected according to the actual situation.
