Aluminum Tube OPGW Cable 36 core Single Mode Fiber Optic Cable
Description:
The fibers is placed loosely in a sealed and water resistant
stainless steel tube filled with water blocking gel. Two or three
stainless steel optical tubes are helically stranded in the inner
layer of a multiple-layer strandard cable. The multiple loose tube
type is designed mostly for very high fiber count requirement over
48 with the maximum fiber count reaching 144. The multiple loose
tube type can meet the requirement of huge cross and large current
capacity.
Features:
- Cable diameter and weight approximate with another ground wire.
Less additional load to tower, high tensile strength.
- Excellent stainless steel tube stranding technology make the fibers
have good secondary excess length and allow the fibers free
movement in the tube. Which keeps the fiber stress-free while the
cable is subjected to longitudinal stress.
- Optical fibers are protected by stainless steel tubes.
- Excellent security, good bullet resist performance.
- ACSW, AAW and SST stranded design provide wide range combination of
electrical conductivity and mechanical tensile strength.
Characteristic:
- Stainless steel tubes filled with hydrophobic gel provide the
protection and support of the optical fibres.
- Accurate process control ensures good mechanical and temperature
performances.
- Larger diameter, larger fibre count.Stable structure and high
reliability.
- High tensile strength and large short time current capacity to
reach optimum balance of mechanical and electrical properties.
Application:
Optical fiber composite ground wire [OPGW] is suitable for
installation on new power lines with double function of ground wire
and communication. Especially for installation on normal voitage
and extra high voltage power lines. OPGW can replace conventional
ground wire of old power line with increasing fiber communication
function. They conduct short circuit current and provide lightning
resistance.
