ADSS Optical Fiber

Description : 

ADSS design is a kind of typical stranded loose tube design, which including two typical structures with maximum (but not limited to) fiber count of 72 and 144. Fibercore-plus could make special design according to customer's requirement.

-Central strength member, normally adopt FRP (YD/T 1181.1), also plays the role of anti bend break member. For maximum 144 fiber design, proper materials could be covered on outside of the FRP.

-Adopting loose tube design as fiber unit, normally, PBT (BG/T118.12001) is used as tube materials. Optical fibers with proper excess length and filling compound with excellent water-block performance are put or filled into the tubes.

-Black PE (BG/T 15065) is placed outside of stranded optical units, forms cable core, water-block compound (YD/T 839.9( is placed in the interstice of the cable core.

-Maximum operation tensile strength could be calculated according to customer's requirements to cable strength or according to weather condition and span-sag requirement, thus the quantity or aramid-yarn should be used could be determined. The yarn is applied with balanced-torque, could also play the role of bullet-proof.

-According to international and national standards, the outer sheath of ADSS could be classified into class-A and class-B, which is suited for spatial potential environments of below and above 12kV respectively.
