OPGW cable erection before the work
OPGW cable erection before the work
OPGW optical cable generally in the line design, the design department should be combined with the actual situation of the line, determine whether the need to set up good conductor ground wire, determine the type and length of good conductor ground wire, control the maximum use of tension of the ground wire distance conditions and tower head size, And determine the suitable OPGW short-circuit current capacity tI2t and the limit value of the maximum service tension that can be accepted by the load condition of the tower, and the latter can be multiplied by the coefficient of 2.5 ~ 8 to become t···

How to troubleshoot the failure of optical fiber circuit
How to troubleshoot the failure of optical fiber circuit
It is difficult to eliminate the faults of optical fiber circuit, but they cannot be eliminated without the four methods of direct analysisThe most direct method to judge whether the fault occurs in the transportation of optical fiber circuit is to analyze and judge according to the actual situation. This method can be applied to the analysis of various situations of the circuit.

Main factors of electric corrosion in ADSS optical cable line
Main factors of electric corrosion in ADSS optical cable line
The ADSS cable subjected to tension during operation is in the strong electromagnetic field existing in the space around the wire, and the capacitance coupling between the cable and the earth makes it in a space potential position. Under the action of space potential, the wet or dirty (inevitable) surface of the optical cable will produce a ground leakage current and heat, the heat will make the optical cable surface water evaporation, random (uncontrollable) to form a dry zone, blocking the surface leakage current. When the potential at both ends of the strip is high enough, a discharge is ge···

Optical fiber lightning protection measures
Optical fiber lightning protection measures
With the development of network, optical fiber, as a medium used to transmit data in the integrated cabling system, is more and more used by people because of its advantages such as high transmission rate and long distance. It is well known that optical fiber is have no electrical conductivity, can from impact current, fiber optic cable has good protection performance, the metal components of cable insulation value is higher, lightning current into the cable not easily, but because fiber optic cable has to strengthen the core, especially directly buried cable armoring layer, when optical fiber···

ADSS cable fittings and accessories selection
ADSS cable fittings and accessories selection
For hanging fittings, tensile fittings, shock-proof whips and other ADSS fixtures, fittings designed by professional ADSS optical cables are used. The optical cable fittings are not only designed to accommodate the size range of ADSS optical cables, but also ensure that the extreme contact pressure under the fittings will not exceed ADSS. Extrusion design limit of fiber optic cable.
