Grounding wire for optical cable lines
An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and telecommunications. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire. The. HistoryAn OPGW cable was patented by BICC in 1977 and installation of optical ground wires became widespread starting in the 1980s. In the peak year of 2000, around 60,000 km of OPGW was installed worldwide. Asia, especially. Several different styles of OPGW are made. In one type, between 8 and 48 glass optical fibers are placed in a plastic tube. The tube is inserted into a stainless steel, aluminum, or aluminum-coated steel tube, with some slack lengt. Optical fibers are used by utilities as an alternative to private point-to-point microwave systems, or communication circuits on metallic cables. OPGW as a communication medium has some adva.

When should cable trays not be connected to crossover lines
Avoiding Crossovers and Congestion: If trays must intersect, use multi-level layouts or bridges to avoid physical cable crossovers. This reduces cable wear and makes individual cable trays easier to access for repairs and upgrades. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. Assuming you're talking about hung cable tray (not cable tray on the floor. cables can usually (not.

Aerial optical cable lines are susceptible to lightning damage
Although the signals in fiber cables are optical signals, most of the outdoor optical cables using reinforced cores or armored optical cables are easy to get damaged under lightning because of the metal protective layer inside the cable. If an optical cable contains metal elements in its design, then they are exposed to current, the value of which can reach several tens of ki-loamperes. It is the magnitude of the current during lightning strikes and the consequences of its impact on objects that have always attracted the at-tention. Fiber optic cables have good protection performance, and the metal components of cable's insulation value is so high that lightning current can not enter the cable easily.
