Product Desciption

Product Name:
Optical fiber composite overhead ground wire(OPGW)







1, Application: 
OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system, adding of communication lines and conduction of short-circuit current or provision of anti-lightning protection. 


2, Feature: 

 

1. Diameter of the cable is small with a low additional load to the pole and tower.
2. Design of stainless steel tube is reasonable and excess lengths of the fiber is correct.
3. Stainless steel tube protects the fiber with powerful tensile strength.
4. Optical unit of the stainless steel tube is the interlayer of the cable and it can resist twist and has good lateral pressure performance.
5. With good safety performance and strong shooting resistance performance,  not easy to be stolen
6. Different armor combinations or meeting different combinations of electrical and mechanical property. 

3, Section diagram:
OPGW cable has two constructions:  
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 control temperature rise during short circuit conditions.
This type can accommodate up to 48 fibers in a cable. Despite such a high fiber count in a single tube, each optical fiber is clearly distinguishable utilizing a fiber identification system consisting of coloring and the number of ring marks on it. This compact design features high mechanical strength and fault current rating within a smaller diameter. The smaller diameter also results in excellent sag tension performance.
Multi 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 cable. 
The multi loose tube type is designed mostly for very high fiber count requirement over 48 with the maximum fiber count reaching 144. The multi loose tube type can meet the requirement of huge cross and large current capacity.
