All Dielactric Self-Supporting Aerial Cable DYSFO (ADSS)

Giới thiệu

YOFCA DSS cable is loose tube stranded. Fibers are positioned into a loose tube made of high

Modulus plastics. The tubes are filled with a water resistant filling compound. The tubes (and fillers) are stranded around FRP (Fiber Reinforced Plastic) as a non-metallic central strength member into a compact and circular cable core. After the cable core is filled with filling compound, it is covered with a thin polyethylene (PE) inners heath. After two layers of Aramid yarns are applied in two directions over the inner sheath as strength member, the cable is completed with PE or AT (anti-tracking) outer sheath

 

Đặc điểm

1.    Can be installed without shutting off the power

2.    Excellent AT performance. The maximum inductive at the operating point of AT sheath can reach2 5kV

3.    Light weight and small diameter educing the load caused by ice and wind and the load on towers and backdrops

4.    Large span lengths and the largest span is over 1000m

5.    Accurate control on Aramid application greatly improving the strength of cables . Accurate fiber excess length and stranding pitch to ensure the good performance of tensile strength and temperature

6.    The design life span is over 30 years

 

 

 

 

 

 

 

 

 

 

 

 

Ứng dụng

The actual status of overhead power lines is taken into full consideration when ADSS cable is being designed. For overhead power lines under 11OkV, PE outer sheath is applied. For power lines equal to or over 11OkV, AT outer sheath is applied. The delicate design of Aramid quantity and stranding process can satisfy the demand on various spans.

Note:

1.    Only a part of ADSS cables are listed in the table. ADSS cables with other spans can be inquired from YOFC directly.

2.    Specifications in the table are got on condition that there is no height difference and the installation sag is 1%.

3.    Fiber count is 2 to 60. The identification of fibers complies s.ith the national standard.

4.    Fibers, either single-mode or multimode, can be used in the cable on request.

5.    Specially designed cable structure is available on request.

6.    YOFC reserves the right to revise the specifications in the table.
