Unarmored ADSS outdoor Fiber Optic Cable with 200M to 1000M Span

Unarmored ADSS outdoor Fiber Optic Cable with 100M to 1000M Span

Description:

ADSS (All-Dielectric Self-Supporting) cable is ideal forinstallation in distribution as well as transmission environments, even when live-line installations are required.

(ADSS) cable is a type of optical fiber cable that contains no conductive metal elements. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission lines and often sharing the same support structures as the electrical conductors.
ADSS is an alternative to OPGW with lower installation cost. The cables are designed to be strong enough to allow lengths of up to 700 meters to be installed between support towers. ADSS cable is designed to be light weight and small in diameter to reduce the load on tower structures due to cable weight, wind, and ice.
In the design of the cable, the internal glass optical fibers are supported with no strain, to maintain low optical loss throughout the life of the cable. The cable is jacketed to prevent moisture from degrading the fibers. The jacket also protects the polymer strength elements from the effect of solar ultraviolet light.
Using single-mode fibers and light wavelengths of either 1310 or 1530nm, circuits up to 100 km long are possible without repeaters. A single cable can carry as many as 144 fibers.



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.
