ADSS Fiber Cable

 

ADSS Fiber Cable, ADSS optical fiber is used for high-voltage transmission lines, using power system transmission towers, the entire optical cable is a non-metallic medium, self-supporting suspension. ADSS optical cable Located on the power tower where the electric field intensity is the smallest. Loose tube construction, tubes jelly filled, elements (tubes and filler rods) laid up around non-metallic central strength member, polyester yarns used to bind the cable core, water blocking tape wrapped around the cable core, then aramid yarn reinforced and PE outer sheath. In summary, ADSS Cable is a type of optical fiber cable that stands out for its all-dielectric, self-supporting construction, offering reliable and efficient data transmission solutions for modern communication networks.

 

Fiber color in each tube starts from No. 1 Blue.

1	2	3	4	5	6
Blue	Orange	Green	Brown	Gray	White

 

B The power line to be erected:

a: Rated voltage and maximum operating voltage

b: Tower type and wire, ground wire type and layout

c: Tension section length, standard Gap (represents the span, the maximum horizontal span, the maximum vertical span)

d: The maximum sag of the conductors and ground wires of each tension section.
