The GYXTW type optical cable places the optical fiber in a loose sleeve made of high modulus plastic, the sleeve is filled with waterproof filler, the sleeve is lengthwise wrapped with a layer of PSP, and the water-blocking material is filled between the PSP and the sleeve. Two parallel steel wires are placed on both sides of the steel strip, and the optical cable is covered with a PE sheath.
Features
Good mechanical properties, good high temperature resistance
Loose casing with high strength and resistance to hydrolysis
Special casing fillers play a key role in protecting optical fibers
Anti-extrusion, good flexibility
PSP enhanced moisture resistance
Two parallel wires ensure tensile strength
Light weight, SMall diameter, easy installation
