Description: GYTA53 direct buried tube fiber optic cable
GYTA53 fiber optic cable Characteristics
Can be installed without shutting off the power
Excellent AT performance, The maximum inductive at the operating point of AT sheath can reach 25kV
Light weight and small diameter reducing the load caused by ice and wind and the load on towers and backprops
Large span lengths and the largest span is over 1000m
Good performance of tensile strength and temperature
The design life span is 30 years
GYTA53 fiber optic cable Application
The actual status of overhead power lines is taken into full consideration when ADSS cable is being designed. For overhead power lines under 110kV, PE outer sheath is applied. FOR power lines equal to or over 110kV, AT outer sheath is applied. The dedicate design of aramid quantity and stranding process can satisfy the demand on various spans
