ADSS All Dielectric Self Supporting Aerial Fiber Optic Cable With FRP Central

Product Specification

All Dielectric Self-supporting Aerial Fiber Cable ADSS 2~288core with FRP central strength member

Description:

ADSS fiber optic cable is also called all-dielectric self-supporting fiber optic cable. All-dielectric fiber optic cable is made of all-dielectric material. Self-supporting fiber optic cable means the fiber optic cable can bear self-weight and external load. Because it is self-supporting, so its mechanical strength plays a decisive role, the use of all-dielectric materials because the cable is in a high-voltage and high-voltage environment, must be able to withstand the impact of strong electricity. Since it is used overhead on the power tower, it is necessary to have matching hangers to fix the optical cable to the tower.

ADSS 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 a 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 thin PE (polyethylene) inner sheath. After stranded layer of aramid yarns are applied over the inner sheath as strength member, the cable is completed with PE or AT (anti-tracking) outer sheath.

Characteristics.

A: The atenuation of fiber transmission is small,low dispersion to make sure fiber cable with excellent transmission performance.

B:Reasonable design, exact lengthiness controlling and cabling method,to make sure fiber cable with excellent mechnical performance and environment performance.

C:Adopt SZ stranded instructure,it is easy for branch,to make sure fiber cable will not be influenced by stress at the harsh environment.

D:PBT loose tube with good performance,and tube filled with thixotropy gel,it can protect fiber better.

E:Outside of strength member and inside of fiber are filled with water blocking gel,to make sure the whole cross section of fiber cable block water.

F:cable with light weight,thin outer diameter,to reduce the load by ice and wind and the load on towers
and backprops

G:Convenient operation and installment,it can use the owened tower,to save cost.

H:Can be installed without power off.H-Lin Group has the most advanced domestic ADSS aramid yarm stranding equipment, with the United States Dupont K49 series of high modulus aramid yarn, we can customized for clients at span range from 100 m -1800 m high quality ADSS cable.

Investing millions of dollars on national laboratory, we can provide the high and low temperature test from minus 70 degrees to 120 degrees, UV aging test, salt spray corrosion test, high tension, high torsion experiment, arc corrosion test, etc., to win customers praise with the excellent quality.

Important notice:

Many small factories are without aramid yarm stranding equipment, aramid yarn is directly into the machine with flat way, tension index of those ADSS cable serious unqualified.

With low modulus aramid yarn or inadequacy aramid yarn even the high strength yarn which is with just 1/15 cost of aramid yarn as the aramid yarn , the ADSS cable will break in a short time after installing.

In same cases, ADSS need arc-resistant sheathing materials, that is AT outer sheath. While some factories do not use it which cause the outer sheath corrosion,aging fast or cracked after a period of time.

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.
