What is the minimum distance between the fiber optic cable and the 10KV power line? Two cable all walk metal bridge.
Fiber optic cable is a certain number of optical fiber, in accordance with a certain way to form a cable heart, wrapped in a sheath, and some also covered the outer protective layer, used to achieve optical signal transmission of a communication line. It is composed of cable core, reinforcing steel wire, filling material and sheath. In addition, there are waterproof layer, buffer layer and insulated metal wire as necessary.
Fiber optic cables communicate with light waves, and the electromagnetic waves of power lines will not affect them. There is no electrical corrosion problem, because the cables are protected by an outer sheath. Now, the optical fiber is added directly to the high voltage cable to supply and communicate at the same time, and the composite optical fiber (OPGW) is also directly connected to the high voltage overhead lines. Meanwhile, the power supply of the power grid and the communication between the power grids are also carried out.
Fiber optic cable can be parallel with the 10kV power cable, there is no distance requirements, the two cables in a metal tray, no problem.
