ASU aerial optical cable

Model: ASU
ASU aerial optical cable, 2~12 fibers, jelly filled and fiber contained central loose tube, two FRP 2.0mm, PE outer sheath, G652D SM fiber, detailed specification on your request.

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 300m
◇Good performance of tensile strength and temperature
◇The design life span is 30 years

  1. Manufacturer’s name

  2. Type of wire

  3.  Year and month of manufacture

  4. Length marking each meter along the wire

Applicantion                                                                                

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.
