Description:
The multi-stranded structure of ADSS optical cable is that the optical fiber and the water blocking gel are added to the optical fiber loose tube at the same time. Then wrap different loose tubes around the central reinforcement (usually FRP). And wrap the appropriate aramic yarn according to the demand, finally extrude PE or AT sheath.
