Cross Section Power
Product Description
Central loose tube type
The fibers is placed loosely in a sealed and water resistant
stainless steel tube filled with water blocking gel. This tube
provides protection to the fiber during installation and operation
under severe environmental conditions. Aluminium layer over the
tube is optional. The stainless optical tube is located at the
center of the cable protected by single or multiple layers of
aluminium clad steel and aluminium annoy wires. The aluminium clad
steel wires are shaped trapezoidally around the optical unit to
provide compact construction. The metallic wires provide mechanical
strength to withstand severe installation and operating conditions,
while achieving conductivity to controltemperature rise during
short circuit conditions.
Multiple loose tube type
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.
Application
1. The 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 highvoltage 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.
2. OPGW cable is mainly used in 500KV, 220KV and 110KV lines,
limited by power cut, security and other elements, mostly used in
new lines. Its applications are:high pressure over 110kv, with a
longer span (usually over 250M).
Features
1. Up to 144 fibers
2. Cable diameter and weight approximate with another ground wire.
Less additional load to tower, high tensile strength.
3. 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.
4. Optical fibers are protected by stainless steel tubes.
5. Excellent security, good bullet resist performance.
6. ACSW, AAW and SST stranded design provide wide range combination
of electrical conductivity and mechanical tensile strength.
